About the cynodont in Walking with Dinosaurs

The presence of whiskers implies body hair and suggests that the cynodont was warm blooded. The cynodont and Placerias were distant relatives, but the cynodont was more mammal-like.

This animal has been modelled on fossils of another cynodont found in South Africa called Thrinaxodon. In the Petrified Forest of Arizona, only two molar teeth of a large cynodont have ever been found. These were similar to Thrinaxodon's but suggested a much larger animal.
