I want to know the answer to the following question:
What was the only archosaur to survive the fourth mass extinction?
All the background I'm provided with is that "All this climatic change, however, resulted in a large die-out known as the Triassic-Jurassic extinction event, in which all archosaurs (excluding ancient crocodiles), most synapsids, and almost all large amphibians went extinct, as well as 34% of marine life in the fourth mass extinction event of the world.". Is that enough to answer the question?
Answer: yes
