Theo

Theo is a Triceratops, and Prehistoric Parks first animal.

Personality
When Theo first came to Prehistoric Park, he was aggressive because of his rutting, but his aggression problem has been solved, he appears relatively calm through the Series, even when Matlida, daughter of the Tyrannosaur that attacked him whilst in the Cretaceous, runs past his paddock during the Mass Break Out.

Biography
During Nigel Marven's second day in the Cretaceous he encountered a herd of Triceratops. The next day he finds a herd of Triceratops. The pride of Tyrannosaurus attack the Triceratops herd. A female Tyrannosaurus is gored in the thigh during the attack. The male Tyrannosaurus back off, leaving the wounded Tyrannosaurus to catch her prey alone. It goes after a 3-ton young male Triceratops, Nigel opens the time portal and leads the Triceratops through it by waving his jacket at it matador-fashion. It follows him through but the Tyrannosaurus does not follow. The Triceratops is named Theo and becomes the park's first exhibit. Theo starts persistently charging the same tree, and his neck frill changes color. Susanne thinks that it is rutting. This gives Bob an idea.

The head keeper copes with Theo's rutting by making a "rival" for Theo by using old tires and oddments attached to a tractor to build a crude mock Triceratops head and neck on the front of a tractor, providing something for Theo to take his aggression out on.

For most of the Series, Theo’s part has mostly been cameo appearances. As for now his aggression problem has been solved, he appears relatively calm through the Series, even when Matlida, daughter of the Tyrannosaur that attacked him whilst in the Cretaceous, runs past his paddock during the Mass Break Out.
