ArticleBody:For the first time, razor sharp teeth of tyrannosaurs were found in the Bexhill-on-Sea region of coastal East Sussex, England. These teeth indicate that a bevy of carnivorous dinosaurs including tyrannosaurs, spinosaurs, and members of the Velociraptor family stalked this region about 135 million years ago. The findings are detailed in a study published December 5 in the journal Papers in Palaeontology.
Barker et al. In this new study, the team deployed several techniques to analyse the fossilized teeth because they were complex and they didn’t have complete skeletons to work with. They analyzed the species’ evolutionary history and used statistics methods and machine learning to help classify the specimens. “Assigning isolated teeth to theropod groups can be challenging, especially as many features evolve independently amongst different lineages.
Dave Brockhurst. Since theropods are exceptionally rare at the site, Brockhurst has only found 10 or so specimens in the area over three decades. “As a child I was fascinated by dinosaurs and never thought how close they could be,” Brockhurst said in a statement. “Many years later I started work at Ashdown and began looking for fossils. I’m happy with tiny fish scales or huge thigh bones, although the preservation of the dinosaur teeth really stands out for me.
