One of the Triassic's most bizarre animals. The Thrinaxodon is a missing link between reptiles and mammals.
— Allen Johnson, about Thrinaxodon
in New Blood


Thrinaxodon (name meaning ''Trident Tooth'') is a genus of cynodonts which lived during the Mid to Late Triassic in what are now South Africa, North America, and Antarctic.

In the Series 2 premiere "New Blood", a pair of Thrinaxodon were brought to the park from Late Triassic Arizona, 225 million years ago. They reside in the Underground Hotel Enclosure where they eventually layed their eggs and welcomed hatchlings.
