Therocephalians were ancient synapsids that lived during the Permian and the Triassic epochs and which were related both to gorgonopsids and cynodonts. They were featured in the last episode of Walking with Monsters where they hunted lystrosaurs. It later evolved into a Cynodont in the Mid-Triassic. Their attacks were swift and at first appeared unsuccessful, but these predators had a secret weapon: a venomous bite, as shown when one kills a lystrosaurus.
Still, only one species of therocephalian has been deduced to be venomous, Euchambersia, which would probably mean that this was the species appearing in Walking with Monsters.
Euchambersia was 3 feet (1 meter) long.
In Walking with... SeriesEdit
A group of therocephalians (most likely Euchambersia ) were in the last episode of Walking with Monsters. The leader of the pack bit a Lystrosaurus and the venom killed it. The predators then feasted on the kill.

A pack of therocephalians appeared during S4 of Primeval in a high school via a time anomaly. Eventually, they were all driven back through it by the ARC field team.
- The model of the cynodont from New Blood was used for the therocephalian.
