Lystrosaurus was a herbivorous dicynodont from the early Triassic.
Early Triassic -
Primeval Resurrected Episode 1.2
When an anomaly opens by a gas station, a large herd of Lystrosaurus come through. The herd had been in the midst of their annual migration, and they panic, seeing as this is not part of their usual migration route. The ARC team comes, and Matt notices that the anomaly is about to close. Becker borrows a truck, and herds the Lystrosaurus back through the anomaly. However, the anomaly closes before the last animal can make it through. The team decides to keep it in the Menagerie until it can be returned home, and Abby names it Thor. He is put in the same enclosure as Sid and Nancy, since their species are closely related.
Abby briefly watches Thor, as well as Sid and Nancy, in their enclosure before she is greeted by Rex, who flies up behind her.
- The Lystrosaurus from the episode were considerably larger than any specimens known from fossils, closer in size to its relative Placerias.
