趣味知識

Bicharracosaurus was named in 2026, making it a very recently discovered dinosaur.3

The name comes from 'bicharraco', an informal Spanish word for a big animal, used by the farmer who found the fossils.1

Its fossils include a partial backbone and a piece of the hip bone, found on a farm in Patagonia.1

Scientists think Bicharracosaurus was an adult when it died, based on the bones' internal structure.1

It lived during the Late Jurassic Period, about 157 to 150 million years ago.1

Bicharracosaurus is a macronarian, a group of sauropods that includes giants like Brachiosaurus.1
