Paleontology in South Carolina facts for kids
Paleontology is the study of ancient life, like dinosaurs and other creatures that lived long ago. In South Carolina, scientists have found many amazing fossils that tell us about the state's past. Millions of years ago, parts of South Carolina were covered by a warm, shallow sea. This sea was home to tiny creatures called trilobites. While many ancient periods are missing from South Carolina's rock record, fossils from the Cretaceous period show us that the state had both marine life and land plants. Later, during the Cenozoic era, sea levels changed a lot, and the area was home to sharks, whales, and even giant crocodiles.
One of the most important fossil discoveries in North America happened right here in South Carolina. In 1725, African slaves digging in a swamp found large teeth. They knew these teeth came from an elephant-like animal, showing a deep understanding of natural history!

South Carolina's Ancient Past
Scientists haven't found any fossils in South Carolina from the very earliest time, the Precambrian period. So, the state's fossil story begins later, in the Paleozoic era.
Life in the Cambrian Sea
During the Cambrian period, a long, long time ago, at least the area around Batesburg-Leesville was underwater. This ancient sea was home to small, shelled creatures called trilobites. Imagine tiny, armored bugs crawling on the seafloor!
Missing Time Periods
After the Cambrian, there's a big gap in South Carolina's rock record. This means we don't have any rocks or fossils from the Ordovician, Silurian, Devonian, Carboniferous, or Permian periods. It's like a few chapters are missing from Earth's history book in this area. The same goes for the Triassic and Jurassic periods of the Mesozoic era, which is when many famous dinosaurs lived.
Cretaceous Period: Dinosaurs and Sea Life
Luckily, the story picks up again in the Cretaceous period. During this time, much of South Carolina was covered by seawater. The ocean was full of life, including oysters and tube-shaped worms.
Sometimes, whole dinosaur bodies would get washed out to sea after they died on land. Bits of their bones and teeth have been found in the eastern part of the state. So, while dinosaurs didn't live in the ocean, their remains ended up there!
Later in the Cretaceous, the seas were home to many different invertebrates (animals without backbones). These included bryozoans (tiny colonial animals), coelenterates (like jellyfish and corals), gastropods (snails), pelecypods (clams and oysters), and scaphopods (tusk shells). The Peedee beds, a rock formation from this time, are famous for their belemnites (ancient squid-like creatures) and other mollusks.
On land, the plant life was very diverse. Trees like eucalyptuses, laurels, magnolias, oaks, sequoias, walnuts, and willows grew in South Carolina. Similar fossil trees have been found in nearby states like Alabama, New Jersey, and Maryland.
Cenozoic Era: Sharks, Whales, and Changing Climates
The Cenozoic era followed the Cretaceous, and during this time, limestone rocks became common in South Carolina. These rocks are packed with fossils!
Early Cenozoic Seas
During the Eocene epoch, South Carolina's seas were home to beautiful corals like Coelohelia wagneriana and Haimesiastraea conforta, as well as the oyster Ostrea arrosis. Before they were found in South Carolina, these corals were only known from Alabama. The Eutaw Springs area alone has preserved at least 58 different kinds of tiny bryozoans from the Eocene!
Middle Cenozoic Marine Life
Later in the Cenozoic, special rock layers called phosphate beds formed. These beds are full of marine fossils like shark teeth, fish bones, and ray dental plates. The climate also started to get warmer, eventually becoming similar to modern-day Florida.
Both land and sea environments existed. The oceans were home to whales, while on land, large crocodiles roamed. During the Oligocene epoch, South Carolina's waters had many bony fishes, sharks, and rays. A very old type of toothed whale, called Xenorophus sloanii, was found preserved in Charleston County.
Later Cenozoic Discoveries
The Miocene epoch brought a huge variety of mollusks to South Carolina, leaving behind countless fossil shells. In the Pliocene epoch, mollusks and sea urchins were common.
Quaternary Period: Ice Ages and Modern Plants
The Quaternary period, which includes today, saw both sea levels and temperatures rise and fall many times. During colder periods, jack pines (a type of tree) grew in the state. When it was warmer, the plants looked more like the ones we see in South Carolina today.
Fossils from the Pleistocene epoch (part of the Quaternary) are quite rare, except for the many marine mollusk shells found at the Stono River and Yonges Island.
A Key Discovery in History

In 1725, a botanist (someone who studies plants) named Mark Catesby visited a plantation called Stono. There, African slaves were digging in a swamp and found several very large fossil teeth.
The slaves immediately recognized the teeth as belonging to an elephant. They were familiar with modern African elephants from their homelands, likely in Angola or Congo. At the time, many Europeans might have thought these teeth belonged to giants from old stories. But Catesby, who had seen African elephant teeth in London, agreed with the slaves' identification.
Years later, in 1806, a famous scientist named Georges Cuvier wrote about this discovery. He noted that the African slaves at Stono understood the connection between these ancient mammoth remains and modern elephants even before European scientists did. In 1942, another scientist, George Gaylord Simpson, admitted that the African slaves at Stono were indeed the first to scientifically identify a vertebrate (an animal with a backbone) fossil in North America!
