About Spiclypeus
What it was like
Spiclypeus was a horned dinosaur with a broad frill edged with spikes, some curling forward and some sticking out sideways. Its brow horns pointed out to the sides. The skeleton belonged to an old animal with a diseased arm, which may have limped for years.

It lived in the Late Cretaceous, in what is now Montana. It comes from the Judith River Formation, where it shared the land with the tyrannosaurs Daspletosaurus and Gorgosaurus and the duckbill Corythosaurus.
How it was found
Mallon and colleagues named Spiclypeus in 2016. The type species is Spiclypeus shipporum.
