"Prehistoric Plesiosaur's Final Meal Unveils New Ancient Species"

The stomach contents of a plesiosaur named Eric, who died between 66 and 208 million years ago, have revealed a previously unknown species of fish, according to a study published in Alcheringa: An Australasian Journal of Paleontology. Researchers used X-rays and CT imagery to create a 3D model of Eric's gut, which showed gastroliths and other material the plesiosaur had eaten in his final days. The discovery could help scientists understand changing ecosystems and predict how modern animals such as dolphins or whales might respond to climate change.
