Triceratops

Triceratops is a ceratopsian dinosaur from late cretaceous North America. One was captured by Helen cutter but was released and captured by the ARC, this animal was named "Horus" by Opkornius. this animal has thicker horns then the pervious triceratops it is suggested that Horus is a male and the others are female. Later on an anomaly opened and a female and her baby came through into the forests outside the city.

Horus himself has a green colour scheme, with cyan stripes on his frill and longer brow horns that are thicker, and a creamy underbelly. When he was called a "she" by Benjamin he looked at him offended while his mate comes and nuzzles the child.

it's quite apparent that Triceratops and other medium and large animals are afraid of trilobites, since Horus, a gorgonopsid named "sir. sabre teeth" and many other animals in the ARC fled when the tiny animals entered the building. Later on Horus was seen in a stampede along with Kentrosaurus, gorgonopsid, Wooly mammoth, allosaurus and Ankylosaurus fleeing from a Therizinosaurus pack.
