Field notes

About Papiliovenator

What it was like

Papiliovenator was a small feathered troodontid, known from a skull and part of the skeleton. Some of its back bones had a butterfly-shaped feature, which gave it its name.

Its world

It lived in the Late Cretaceous in what is now northern China. Its bones come from the Wulansuhai Formation, where it shared the land with Protoceratops, the raptor Linheraptor and the small troodontid Philovenator.

How it was found

Pei and colleagues named Papiliovenator in 2022, from a single find.

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 Papiliovenator.

The evidence

The science behind Papiliovenator

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

From its own fossils

  • A nearly complete skull and parts of the skeleton belong to an animal that was still growing.
  • Its snout was short, unlike the longer snouts of many other troodontids.
  • The arches of its frontmost backbones spread outward into a butterfly shape.

Borrowed from relatives

  • Feathers are restored by comparison with feathered troodontids such as Jianianhualong.
  • Missing parts of the limbs and tail are modeled on other troodontids, including Linhevenator.

Still unknown

  • Its feather colors and patterns.
  • How its proportions changed as it reached adulthood.
  • Which foods it ate most often.
