Why did Diictodon disappear?
Extreme warming, aridity and vegetation collapse during the end-Permian mass extinction ended the species.
03 / EVIDENCE
How do scientists know about Diictodon?
Thousands of skulls and skeletons show variation in tusks; occupied burrow casts provide direct behavioral evidence.
