Shoreline Herding in Dinosaur Tracks

Researchers documented more than 16,000 dinosaur footprints across contiguous outcrops in Carreras Pampa, Torotoro National Park (Bolivia), dating to the Upper Cretaceous. Track orientations, overlapping pathways, tail and swimming traces imply repeated shoreline use, group movement along a lake margin, and a mix of walking and swimming behaviors. — A site‑scale behavioral dataset of this size provides concrete evidence for herd movement, habitat use, and paleoecology that changes how we teach and communicate Mesozoic ecosystems and can influence conservation and heritage policy for fossil sites.
