酷東西

趣味知識

Erythrovenator is known from just one fossil: the top part of a left thigh bone. This bone was colored red by the mudstone it was buried in, which is how the dinosaur got its name 'red hunter'.1

Scientists think Erythrovenator was one of the very first theropod dinosaurs, living around 233 to 225 million years ago.1 4

The only known Erythrovenator fossil was found at the Niemeyer Site in Brazil, a place where many fossils of a different animal, the cynodont Siriusgnathus, have been found.1

Erythrovenator's thigh bone has a special shape that helps scientists tell it apart from other early dinosaurs. The front part of the bone is shaped like a pyramid.1

When Erythrovenator was alive, South America was part of the supercontinent Pangaea, and the climate was much different than it is today.1
