Permian Extinction Survivors & the Recovery That Followed
What counts as a survivor? Separate a lineage crossing the Permian–Triassic boundary from animals that flourished later, then explore three atlas records from recovering Triassic ecosystems.

How this list was selected
The cited Karoo studies identify Lystrosaurus curvatus across the boundary. Our atlas record is Lystrosaurus murrayi, a different, Early Triassic species: it must not be presented as a proven boundary survivor. The linked animals below illustrate the recovery after the extinction, not three demonstrated survivors. Rounded age ranges alone cannot establish survival; stratigraphic evidence and taxonomic identity both matter.

Animals of the recovery
3 atlas recordsAbout 255–248 million years ago
Lystrosaurus
Lystrosaurus murrayi
Lystrosaurus murrayi became common in the Early Triassic. This record illustrates recovery; evidence for L. curvatus crossing the boundary cannot be transferred to this species.
Southern Africa · India · Antarctica
About 252–247 million years ago
Thrinaxodon
Thrinaxodon liorhinus
A whiskered snout, differentiated teeth and burrowing life approach the mammalian body plan.
Seasonal river plains · South Africa and Antarctica
About 247–242 million years ago
Erythrosuchus
Erythrosuchus africanus
An enormous deep skull sat on a relatively low body in this early archosauriform apex predator.
Semi-arid river plain · South Africa
