One of the most frequently asked questions we hear from clients is “Why are there so many fossils in Summerville, South Carolina and how did they get here?” Well, in order to answer that complicated question, I decided to prepare this article.
Today, the Coastal Plain of South Carolina is covered in forests with a semi-flat topography towards the coast and a “rolling hill” effect moving towards the midline of the state with the Summerville and Charleston areas being located at the low-point of elevation in terms of a side-to-side view of the topography of the Coastal Plain.
In other words, if you were to create a 3D model of the topography of the Coastal Plain of South Carolina and then look at it as if you were standing on the beach looking towards Columbia, the Summerville and Charleston area would appear to be sitting within the “V” of elevation with the elevation ascending in all directions towards South Carolina state lines. Of course, there are other areas of the state that would fit this profile as well, such as Colleton County, Beaufort County, etc. as all of these areas make up what is known as the Lowcountry of South Carolina.
Now let’s jump back in time to around 60 million years ago – a time known as the Eocene. South Carolina would have looked significantly different during that time. The Eocene was a time of high sea level, during which the coastline of South Carolina was located all the way in Columbia – which is now located at the mid-point of the state – more than 120 miles from where the coast line sits today. During this time, the lower region of the modern Coastal Plain of South Carolina was deep Ocean and nothing more than a dark sea that was home to micro-foraminafora, cow-sharks, and goblin sharks, and other deep-sea dwelling creatures.
As the years passed by the ocean remained high, with the modern day Coastal Plain remaining deep Ocean for millions of years. Over this time, countless micro-foraminafora died and settled to the bottom of the ocean floor, slowly building up the ocean floor to create a limestone formation that is several hundred feet thick. The Eocene limestone strata are divided into three units (layers) – the Harleyville Formation, Parkers Ferry Formation, and the Tupelo-Bay formation.
The Harleyville formation is a dark green limestone and clay layer and represents the uppermost (or latest point of) the Eocene. The Parkers Ferry formation is a yellow limestone that separates the Harleyville formation and the Tupelo-Bay formation. The Tupelo-Bay formation is the thickest Eocene unit in South Carolina and is several hundred feet thick and is where many of the Eocene-whale specimens housed in museums around the state of South Carolina. The only known exposures of the Eocene units in South Carolina are located within the Cement quarries of Harleyville South Carolina.
Towards the end of the Eocene, the earths climate fell into a state called an “Icehouse” effect. During this time massive continental sized ice sheets formed, lowering the volume of water in the Oceans and causing sea levels to drop. As a result, the earth suffered a mass extinction event known now as “the Lost Extinction”.
The name “The Lost Extinction” comes from the fact that this Extinction event remained in the shadows until recent years. It is only in the last year in fact that we have seen enough documentation of the event to support the naming of this event into the M.E.’s of earths history. During “The Lost Extinction” the climate on earth was undergoing such extreme changes that it inevitably forced the biggest player in evolution out of its cave and back into ecosystems all around the world – environmental pressure.
Over the next few million years the world’s Oceans saw a decrease in productivity, changes in migratory patterns and feeding cycles, disconnections between prey and predator, the Extinction of multiple species, and the rise of new species. It is during this time that we see the extinction of the Archaeocetes and the rise of the Archaeomysticetes (the first filter feeding whales and ancestors to modern Baleens) and Odontocetes (toothed whales that bore a stronger resemblance to modern dolphins than to their ancestors the Archaeocetes). It was also during this time that we saw the fall of the Carcharocles auriculatus (great-grandfather in evolution to the megalodon) and the rise/evolution of the Carcharocles angustidens.
33.9 Million Years – The birth of the Oligocene
It is 33.9 million years ago, the dawn of the Oligocene, and the Coastal Plain of South Carolina is once again submerged beneath deep Ocean. This time however, the coast line ends just below Harleyville, South Carolina and although the Summerville and Charleston areas are still deep Ocean, the water depth is roughly 100 feet shallower than it was towards the beginning of the late Eocene (35 million years ago).
The Oligocene formations are a very important feature of South Carolina – South Carolina is one of only a handful of locations around the world where the Oligocene marine strata are landlocked – meaning that they can be studied on dry land. Why is this important? Because it was during the Oligocene that we saw the rise of the ancestors to modern dolphins, whales, and sea-turtles. It was during the Oligocene that we saw the birth of the first Baleen whale, the first Xenorophid, the first Waipatiid, and so much more! Okay, let’s fast forward a few million years.
We are now at 26-23 million years and the climate is once again changing bringing about a fall in sea levels. We can see this shift today through the study of geologic strata such as the Ashley Formation (a thick limestone layer representing the early to mid Oligocene) and the Chandler Bridge formation (a clay and sand layer representing the later portion of the middle Oligocene through the late Oligocene). The Chandler Bridge formation represents a time in South Carolinas history when much of the modern Coastal Plain was the equivalent of salt water marshes and inter-tidal zones. The contact point of these two strata can be observed in many locations throughout the Summerville area of South Carolina in creek bed exposures and the occasional construction site. The Chandler Bridge formation is perhaps one of the most important Oligocene marine units on the Eastern seaboard.
Within the Chandler Bridge formation lies the secrets of evolution of most modern dolphins and the secrets of the grandfather in evolution to the Megalodon – The Carcharocles angustidens. Dr. Bobby Boessenecker’s research team at the College of Charleston recently published a paper on the existence of a C. angustiden nursery that was found right here in Summerville South Carolina. An amazing discovery that showed key similarities to today’s thriving ecosystems and shark nurseries found off of our coast today. Fast forwarding again.
The Miocene – Time of the Mighty Megalodon
During the Miocene the Coastal Plain of South Carolina once again reached beyond Harleyville South Carolina, evidenced by the existence of Great Whites, Bull Sharks, Galeocerdo mayumbensis and more being found in the uppermost sand layers of the Harleyville strata. It was during this time that the Summerville and Charleston areas of South Carolina were a feeding ground for the Megalodon as by that time, what is now the Coastal Plain of South Carolina was home to a diverse population of fish, whales, dolphins, and sea cows thriving in warm and shallow Coastal waters – the ideal temperate habitat for a thriving Coastal ecosystem. Over the course of millions of years Megalodon and other large sharks fed on their prey, shedding trillions of teeth that became buried on the sea floor – only about 1% of these would go on to become fossilized. Fast forwarding again –
The Final Fall
Around 3 million years ago the sea level began to rapidly fall (Coastal regression in scientific terms). With the rapid falling of sea levels and high tectonic activity came continental breaks- shifts/cracks in the continental shelf off the coast. These continental breaks led to continental deposits – large non-conformities/strata that covered thousands of square miles and that contained countless fossils. But wait, there’s more
As sea level continued to fall, the Coastal Plain of South Carolina began to look more and more like what it does today. Rivers formed at the deepest points of elevation, bringing about the erosion of nearly all of the true Miocene formations that once covered the Coastal Plain along with much of the upper Oligocene units. In addition to erosion by rivers, the Coastal Plain was subjected to several rises and falls in sea level within a short time which again contributed to even further erosion of strata across the Coastal Plain. With the erosion of these strata came the erosion of the fossils that they contained. Once caught in the currents of rivers, fossils would be tossed and tumbled along the river-beds until they hit an obstruction in the water column that would allow for them to stop – this process led to the slow build up of what we refer to as gravel beds.
Over time, many of these ancient rivers dried up or became swamps. The rivers that still exist today were once 3 times the size that they are now, bordered by swamp land on all sides offering evidence to how wide they once were. With the newly dry land came terrestrial vertebrates – the Mastadon, Gomphotherium, Mammoth, three-toed horse, Saber-toothed cats, Camels, Giant Beaver, Giant Sloth, Tapir, and more. Withing a few hundred thousand years the Coastal Plain came to resemble what it does today – a thriving Coastal Habitat full of diversity. However, the shaping of mother nature was not done yet. Flooding rains and another swift change of sea level would bring destruction across the Coastal Plain at least 2 more times before things came to be deposited in the way that we see them today – allowing for a wonderfully diverse mixture of marine and terrestrial fossils of all kinds representing nearly 25 million years of geologic time to become mixed together into Lag Deposits across the Coastal Plain of South Carolina.
For a few hundred thousand years, the Coastal Plain saw peace – and then came man. With the ancient rivers all but dried up, development moved in, ditches were formed, creeks were widened, and the strata bearing these ancient gravel beds were once again exposed.
Today, the ditches, creeks and rivers surrounding Summerville sing the songs of ancient life with the fossils they contain. Waters rushing through these channels brings fresh material to their beds, shedding light to the life that once lived here. Imagine the force of nature bearing down on a gravel deposit consisting of millions of years of history, grabbing hold of any lose material and tearing it out into the current – these are the things that the Legends surrounding Summerville Fossil hunting are made of.
Not every creek will contain fossils, and that’s where our research and years of experience come into play. With a combined 75+ years of experience, our team has studied the Coastal Plain more than anyone alive today. We have tracked through every forest, every swamp, and every creek to find exposures of ancient life and to better understand how and why these deposits came to rest where they are today.
So in other words, the Summerville area acted as a catch basin for millions of years of fossils that were eroded from multiple different strata and then deposited into lag layers distributed throughout the area (lag layers are reworked layers of material). It is true that Summerville is one of the top 3 destinations for fossil shark tooth collectors from around the world – and now you know why.
I have to also point out that my article is a “lamens- terms” summary of the years and years of research conducted by geologists (one of the most renowned of which is Dr. Rob Weems) and paleontologists across the state in combination with the years of knowledge and experience of our team. Until next time, Happy Hunting!
The rain is a Fossil hunters best friend in the Lowcountry of South Carolina when it comes to surface and creek hunting. For the creeks, the rain means rushing waters and fresh erosion of the fossil layer. For surface hunting, the rain brings fossils to the surface by pounding away the sediments that have them trapped and hidden just beneath the surface. The forecast showed rain, but as the day went on we all sat and wondered if and when the rain would actually arrive. The sky was filled with dark clouds and the wind was howling, but by mid afternoon we had barely seen a drizzle.
Nightfall came and we descended on the site in search of ancient treasures only to find that the rain had not came like we had hoped. We proceeded to hunt anyways, hopeful that the rain would eventually come – and it did. We were hard at work carving away at the layer when suddenly the rain began falling with a vengeance. Within minutes we were all drenched from head to toe. The site began to flood, the water pooled along the surface of sun-baked clay that had not seen rainfall in nearly a month – and we rejoiced!
The next few days were amazing! We lead our clients through the freshly washed fields for 3 days, picking up Fossil after Fossil. One client took home 6 Megalodon teeth in addition to a variety of other amazing fossils including a gem-quality Isurus retroflexus (a type of Mako shark tooth). All in all, over a thousand fossils were collected within just 2 days time and the wait for the rain began again.

The Basilosaurids were a group of cetaceans that lived during the Eocene epoch from roughly 40 to 33.9 million years ago. Today, the remains of these amazing creatures can be found in Eocene exposures around the world including in the cement quarries in Harleyville, South Carolina. Once a tourist attraction for fossil hunters from around the globe, the Harleyville quarries are now indefinitely closed to public collectors. In the Summer of 2020, we were given a very rare opportunity to hunt the quarry along side the former Vice President of operations of the Giant Cement Quarry – Mr. Rich Familia. It was during this hunt that I discovered the remains of a beautiful pre-historic whale belonging to the Basilosauridae family with the identification being a tie between the Basilosaurus cetoides and the Cynthiocetus sp..I was walking along the edge of the Quarry on the 2nd tier when I noticed bone protruding from the wall – jagged bones indicating partial skeletal destruction by way of Quarry machinery. I called to Joshua and Rich to come over to the area as I began collecting the fragments of bone scattered amongst the limestone. We worked carefully but quickly as we knew whatever we could get out that day would most likely be all that we would be able to recover of the specimen. Amazingly, most of the rostrum and part of the skull had been knocked off of the wall in solid blocks that we were able to carry out with ease – one of which ended up containing both of the tympanic bullas (outer ear bones).For several hours the mine echoed with the sounds of our rock hammers and chisels hard at work against the limestone formation. By the end of the day we had collected over 5 gallon sized zip lock bags full of bone fragments in addition to 3 larger blocks containing larger portions of the whales’ skull and rostrum. No bones belonging to the whales postcranial skeletal remains were recovered though as they had already been taken away by the excavators in the days prior. But there were only happy thoughts for us as we knew how precious it was to have even found the remnants that we had been blessed with that day. Most often these situations result in only a handful of fragmented bone that leads to disappointment with no in-tact specimens – but not this day.Today, the specimen has been prepped (with over 100 hours logged in prep work I might add) with even more work left to do. The frontal most portion of the rostrum now sits on a shelf where I look at it everyday and think of how majestic this great creature once was. My favorite Fossil – The BasilosaurusSkye – The Digger
The specimen was home and ready for prepping – so what comes next? Well it started with cutting open the jacket to once again expose the specimen to the sunlight. Next, it was time to brush away the loose dirt and work the material down to the solid matrix with the bone exposed. I completed these tasks using the “old school paleontology” method of a paint brush and blowing lightly every few strokes. As I worked the material down, I began to see her bone and thought to myself how amazing it was to be the first human to have ever laid my eyes on her. How amazing it was to think that this beautiful creature lived 28 million years ago, 27.8 million years before the human species came into existence as the species that we are today. Her bone lay shattered and yet articulated all at once within her death bed as I dusted the matrix away. Next, it was time to apply a light acid spray over the matrix around the bone to soften the material enough for me to work it. This part of the process is particularly fascinating as the acid causes the matrix to fizzle and break apart. I repeated this process several times over the course of the day until finally, the bone lay pedestaled all of the way down the length of the block – she was ready to be removed. Carefully I began to remove each piece. Piece by piece, removed from the matrix and layer down against a grid line so as to keep the pieces aligned appropriately for the upcoming reconstruction process. Next, I carried the material over to a wash station and used a soft bristled tooth brush to slowly remove the remnants of the matrix and ready the pieces for glue application. Finally, it was time to put her back together and restore her to her former glory. As I reconstructed her bones I slowly watched her coming back to life – telling the story of her life. The worn down enamel crowns showing that she had a hearty diet, that she was an older dolphin that had probably seen many years of babies and many years of an ancient Ocean long gone through the phases of evolution and climate change. A few days later and it was time to carry her to the Mace Brown Museum at the College of Charleston for donation. A bittersweet moment but a significant one nonetheless. See, this particular Waipatiid specimen showed unique signs of a particular type of feeding wear that indicated a certain type of feeding habit that the College was interested in researching. As I handed her over to Dr. B I felt proud in knowing that I had saved her from the destruction of construction equipment and happy to know that she was to be used for furthering future paleontological research. One day there will come a paper that will include scientific notes on her life and what her bones could tell us and that, that is what it’s all about ❤
It was a beautiful sunny day in the field and we had Dana Fleck’s Photography out with us to do a photo shoot for the website. Dana had brought her 6 year old son Kayden along with her for the shoot since they were only stopping through town on their way back home to another state. Kayden had spent the entire walk into the site telling all of us how he was going to find his 6″ tooth that day. We all chuckled a bit as we knew how rare that size tooth could be for that site.
Dana did a wonderful shoot for us (definitely recommend her hands down!) and decided to stick around for some fossiling. Shortly after she started to dig, Kayden walked over to an area where the layer was shelfed off and only about 8″ deep below surface level. He sat down and called for Joshua Basak to come over and dig with him and Joshua obliged. What happened next was almost unbelievable!
Joshua and Kayden were sitting side by side in the dirt, both armed with their small 28″ shovels, blades slicing through layer and suddenly time stopped – the sound of metal hitting a blade! We all heard it, we all knew that sound so well. Kayden turns and looks at Josh and says “Is that my tooth?!” to which Josh replied, “Yes it is!” and the excavation began.
Within minutes we were all surrounding the area watching as Skye extracted the tooth for Kayden and Dana, careful not to damage the tooth. Sounds of excitement grew from the group and with each wipe of the dirt away from the blade, the tooth grew larger and larger. Suddenly it was revealed and everyone gasped in awe at what lay before them – Kayden and Joshua had simultaneously struck the blade of a 6.25″ Megalodon. From within the silence came shouts of excitement and the sound of Kayden’s voice – “God put that there for me” he exclaimed. A moment that brought tears to the eyes of each and every one of us. A moment that we witnessed a young boy find the tooth of his lifetime and watched his dreams come true!
For years there has been a disconnect between the world of academic paleontologists and the world of amateur paleontologists. The academics – responsible for building what we know of the past by way of research, data analysis, and scientific publications into peer reviewed journals. The amateurs – responsible for nothing more than collecting fossils through endless hours of hunting, or at least that’s what most have thought. Today we see a revolution of this relationship taking place. A revolution owed in part to the open mind of Dr. Bobby Boessenecker – the lead “whaleonotologist” at the Mace Brown Museum at College of Charleston. The Mace Brown Museum is a small, non funded museum housed on the 2nd floor of the School of Science and Mathematics building of the College of Charleston in Downtown Charleston and is home to around 15,000 fossils – many of which were collected and donated by local amateur paleontologists over the years.
What makes Mace Brown different? They do not have storage space for specimens so they only take what is deemed scientifically significant and can be used in future or ongoing research. What makes Dr. B different? Dr. B is one of a select handful of academic paleontologists that appreciate the efforts made by amateurs to locate and recover specimens and gladly accepts them for use in his research. As a result, we are now witnessing a new age of academics and amateurs coming together in a beautiful effort to understand more about the marine environment present in the Coastal plain of South Carolina during the Eocene, Oligocene, and Miocene of South Carolina – a feat that has never before been done.
The Palmetto team as a whole believes in supporting the advancement of paleontological research and contributing to the paleontological record for South Carolina and when it comes to our donations of specimens – Dr. B at the Mace Brown Museum is definitely our go to choice! I think my favorite part of working with Dr. B is that when I find something that interests Dr. B, he automatically knows exactly what he wants to use the specimen for and I never have to doubt whether or not my specimen will ever see the light of day again. Knowing that my contributions help give support to his and others research and do not just collect dust on a shelf in a dark warehouse brings me a great deal of comfort. Dr. B, without knowing it, makes way for the dreams of those outside of the academic world to come true by allowing us all to in some way shape or form participate and contribute to paleontological research.
For anyone planning a trip with Palmetto, I would highly recommend scheduling a tour at the Mace Brown Museum as well! Entry is free however donations are gladly accepted! While on your tour you will have the opportunity to see several breath taking specimens including a full room designated specifically to the evolution of whales (by far the most amazing display room EVER), a Megalodon dentry, and much more! You will also have the chance to see the “Amateurs Exhibit” which is a series of cases full of specimens recovered and donated to the Mace Brown Museum that Dr. B and his awesome wife Sarah put together in appreciation of the efforts made by locals to support their research. Trust me, this is definitely a “Must-See” that should part of every fossil hunters trip to the Lowcountry of South Carolina! Thanks Dr. B for being so awesome and we all look forward to working with you more in the future! And for anyone wanting to make donations to the Mace Brown Museum, here’s a link where you can do just that!
