Until recently, evidence for dinosaurs in the northeastern United States was sparse, but over 900 theropod, sauropod, ankylosaur and ornithopod fossilized footprints have now been found just a short drive from the nation’s capital, according to new studies.
The finds, which also include tracks for pterosaurs, a dino-era mammal and other vertebrates, suggest that Maryland was a hotbed for dinosaurs during the Cretaceous from around 98 to 121 million years ago.
