What Dinosaurs Lived in South Carolina?

South Carolina holds a unique place in the study of prehistoric life, despite not being widely recognized for dinosaur discoveries. The state’s geological history presents distinct challenges and opportunities for paleontologists. Nevertheless, significant clues about the dinosaurs that once roamed this landscape have emerged.

Unearthing South Carolina’s Ancient Past

South Carolina’s geological past explains the nature of its dinosaur fossil record. For much of the Mesozoic Era, particularly during the Triassic and Jurassic periods, vast portions of the state were submerged under shallow seas. This limited the preservation of terrestrial dinosaur remains, though the state has a rich record of ancient marine life.

The majority of dinosaur finds in South Carolina originate from the Late Cretaceous Period, when some land areas became exposed. Fossils are often discovered in phosphate mines and riverbeds, rather than through large-scale excavations of intact skeletons. These conditions lead to the preservation of isolated bones, teeth, and bone fragments, making complete dinosaur skeletons uncommon.

Cretaceous Period Dwellers

Dinosaur evidence unearthed in South Carolina primarily dates to the Late Cretaceous Period, specifically the Campanian and Maastrichtian stages (roughly 77 to 66 million years ago). Hadrosaurs, or “duck-billed dinosaurs,” are among the most frequently identified. These large, herbivorous creatures are represented by fossilized teeth and occasional vertebrae. Hadrosaurs, which could grow up to 30 feet long, were plant-eaters with distinctive dental batteries.

Carnivorous dinosaurs, or theropods, also inhabited ancient South Carolina. Remains attributed to the Dromaeosauridae family, which includes raptors, have been found. These finds include a 1.5-inch tooth from Florence County and a claw core and toe bone from the Pee Dee River. Such fragmented evidence suggests the presence of agile, meat-eating dinosaurs, with some discoveries linked to relatives of Velociraptor.

Bones from ornithomimids, or “bird-mimic” dinosaurs, have also been identified. These slender dinosaurs, estimated to be 10 to 13 feet long, had a bird-like appearance, including feathers and beaks, and possessed long, powerful legs for swift movement.

Beyond Skeletal Evidence

While skeletal remains offer direct proof of a dinosaur’s presence, other forms of evidence, known as trace fossils, provide valuable insights into their lives. Dinosaur footprints, for instance, have been found in South Carolina, offering clues about their size, gait, and behavior. These imprints can indicate whether dinosaurs moved individually or in groups, and the type of terrain they traversed.

Isolated teeth are another common and significant find in the state’s fossil record. The durable nature of teeth allows them to survive where more fragile bones might not. For dinosaurs, individual teeth help paleontologists identify species present, even without larger skeletal parts, and infer their diets. This non-skeletal evidence is important for piecing together ancient ecosystems in South Carolina.
