Question: In what area of North Carolina did scientists find what are believed to be the oldest sets of dinosaur tracks on the East Coast?
Answer: Scientists discovered the oldest dinosaur tracks on the East Coast in a mudstone quarry near Leaksville Junction along the Dan River Basin, in the northern North Carolina-Virginia border area. These Late Triassic tracks were made by Grallator, a three-toed, bipedal carnivore similar to small theropods like Coelophysis, and Atreipus, a primitive quadrupedal ornithischian dinosaur.
