It browsed low-growing vegetation in Late Cretaceous Alberta. The Oldman Formation also preserves Daspletosaurus and Saurornitholestes.
Field notes
About Gremlin
What it was like
Gremlin was a small, early horned dinosaur from the leptoceratopsid family. It had a beak and a short frill but no real horns. It is known from a few bones.
Its world
It lived in the Late Cretaceous in what is now Alberta, Canada. Its bones come from the Oldman Formation, where the tyrannosaur Daspletosaurus also lived.
How it was found
Ryan and colleagues named it in 2023. The type species is Gremlin slobodorum. It is named after a creature of folklore.

A rock formation can hold fossils laid down millions of years apart, so not every animal here met Gremlin.
The evidence
The science behind Gremlin
Which parts of the picture come from its own bones, and which come from its relatives.
From its own fossils
- The naming specimen is a right frontal, a bone from the skull roof between the nose and eyes.
- The surface ornamentation of this skull bone distinguishes it from other leptoceratopsids.
Borrowed from relatives
- The beak, short frill and hornless face are restored from leptoceratopsids such as Leptoceratops.
- The limbs and body are modeled on better-known relatives such as Leptoceratops and Ferrisaurus.
Still unknown
- The exact shape of its complete skull and body.
- Its skin covering and color.
- How its skull changed as it grew.
