Field notes

About Arcovenator

What it was like

Arcovenator was an abelisaur, a two-legged hunter with a short, deep skull and tiny arms. It is known from part of a skull and skeleton, and was a medium-sized to large member of its family.

It was closely related to Majungasaurus from Madagascar and Rajasaurus from India, which suggests animals moved between Europe and the southern lands.

Its world

It lived in the Late Cretaceous in what is now southern France, with more finds reported from Spain. Its bones come from red clays near the river it was named after, where it shared the land with the plant eater Rhabdodon, the armored Struthiosaurus and the titanosaur Ampelosaurus.

How it was found

Tortosa and colleagues named Arcovenator in 2014.

Lived alongside

Found in the same rock formations

A rock formation can hold fossils laid down millions of years apart, so not every animal here met Arcovenator.

The evidence

The science behind Arcovenator

Which parts of the picture come from its own bones, and which come from its relatives.

From its own fossils

  • A well-preserved braincase and nearby skull bones show a rough bony brow above the eye.
  • Its known remains include teeth, tail vertebrae and lower leg bones.

Borrowed from relatives

  • The missing snout and much of the body are restored using better-known abelisaurids such as Majungasaurus.
  • Its tiny arms are inferred from relatives, rather than from arm bones of Arcovenator.

Still unknown

  • The complete shape of its jaws and arms.
  • Its skin covering and color.
  • Whether it hunted alone or in groups.
