I want to know the answer to the following question:
What type of reptiles were common during the early Triassic?
All the background I'm provided with is that "Ammonites were common in the seas around Antarctica, and dinosaurs were also present, though only three Antarctic dinosaur genera (Cryolophosaurus and Glacialisaurus, from the Hanson Formation, and Antarctopelta) have been described to date.". Is that enough to answer the question?
