FOSSILS SPECIMEN: THEROPOD DINOSAURS

Fossils are defined as any evidence of prehistoric life. There are two types of fossils: Body Fossils include remains of skeletal bones, shell, carapace, test and teeth. Trace Fossils are clues the organism existed such as foot prints, tracks, burrows and coprolites (fossil dung).

Theropoda meaning “beast foot”, are a diverse group of primarily carnivorous dinosaurs that first appeared in the fossil record in the late Triassic Period around 230 million years ago. Many  non-avian (dinosaurs) theropods went extinct 65 million years ago in the KPG (formerly KT) extinction event. Avian (birds) dinosaurs can be found on every continent today.
