Datu dibertigarriak

Stellasaurus had a long, straight nose horn and small bumps above its eyes, similar to its relative Styracosaurus.2 3

Its skull frill had long spikes called P3 processes, but the other spikes were shorter, giving it a unique look.2 3

Stellasaurus lived about 75.2 million years ago, during the Late Cretaceous period.3

Scientists think Stellasaurus might be a transitional form, meaning it shows features between older and younger horned dinosaurs.2 3

The only known fossil is a partial skull, found in the Landslide Butte area near the US-Canada border.2

Stellasaurus is part of a group called centrosaurines, which are horned dinosaurs with big nose horns and fancy frills.2
