Field notes
About Pendraig
What it was like
Pendraig was a small, slender meat eater only about the size of a large cat, related to Coelophysis. It walked on two legs and had sharp teeth.
It is one of the oldest meat-eating dinosaurs known from the United Kingdom.
Its world
It lived in the Late Triassic in what is now Wales. Its bones come from a quarry where cracks in limestone filled with sediment and bones, the same kind of site that produced Pantydraco.
How it was found
Spiekman and colleagues named Pendraig in 2021. The bones had been collected decades earlier and kept in a museum drawer. Its name comes from an old word of Wales meaning chief dragon.

The evidence
The science behind Pendraig
Which parts of the picture come from its own bones, and which come from its relatives.
From its own fossils
- The main skeleton preserves part of the backbone, the pelvis and a thigh bone.
- The hip bones have a distinctive outline, including a sharply angled rear tip.
Borrowed from relatives
- Its missing head and limbs are restored from early theropods such as Coelophysis.
- Blade-like, serrated teeth and a meat-eating diet are inferred from other coelophysoids.
Still unknown
- How large a fully grown adult became.
- Whether island life caused its small size.
- Its skin covering and color.
