"75-Million-Year-Old Dinosaur Jaw with Trapped Insect in Amber Discovered"

Originally Published 2 years ago — by IFLScience

Scientists have discovered a unique 75-million-year-old fossil of a hadrosaur dinosaur jawbone with a piece of amber attached, containing an ancient aphid, in Dinosaur Provincial Park, Alberta, Canada. This rare find provides insight into the diet and environment of hadrosaurs and demonstrates an extraordinary sequence of events that led to the preservation of both the dinosaur remains and the insect in amber. The study detailing this discovery has been published in Scientific Reports.

"Discovery of a New Plesiosaur Species in the US"

Originally Published 2 years ago — by Sci.News

Scientists have discovered a new genus and species of plesiosaur named Unktaheela specta, based on fossils found in Wyoming and South Dakota, which lived about 80.5 million years ago during the Late Cretaceous. This small polycotylid marine reptile, measuring between 7.5 to 8.5 feet in length, had a wide skull and unique paddles, with eye-shading features suggesting it was adapted for visual hunting in sunlit waters. The findings, which provide insights into the ecological niches of Cretaceous marine reptiles, were published in the journal Cretaceous Research.
