The Ancient Appetites of Triassic Reptiles A 240 million year old reptile fossil found in China has yielded a surprising discovery: the oldest known preserved reptile gut contains fish remains.
This finding, published in Science Advances, sheds new light on the evolution of archosaurs – a group that includes modern birds and crocodilians.
A Glimpse into Triassic Ecosystems The Austronaga minuta fossil is remarkable not only because it's the oldest preserved reptile gut but also because it challenges our understanding of early archosaurs' ecological roles.
