Holotype

 This is the fossilized skull of a panoplosaurus, an armoured herbivore.

Here we have a leptoceratops, an archaic cousin of the horned dinosaurs that lived at the same time as the others.

Hello, beastie.

Fossilized skin impressions, droppings, and footprints tell paleontologists a lot.

Styracosaurus was one of the horned dinosaurs.

In the background casing is an example of anchiceratops.

Below is a holotype- the first example discovered of a species. Chasmosaurus irvinensis is yet another of the family of horned dinosaurs.

Triceratops is one of those dinosaurs whose name is the earliest learned by children.
