Fun facts

Huayracursor had a longer neck than other early dinosaurs from the same time, which helped it reach more plants.1

It lived during the Late Triassic, when the supercontinent Pangaea existed.1

Its skeleton was nearly complete, which is rare for such an old dinosaur.1

It was found with other animals like rhynchosaurs, cynodonts, and aetosaurs.1

Huayracursor shows an early step in how dinosaurs got bigger and developed longer necks.1
