👉 Dethiosulfatarculus is a genus of extinct mammals that lived during the Late Cretaceous period, around 65-63 million years ago. The fossils of this group were found in Europe and are known for their distinctive features such as long snouts, large ears, and a unique skull shape with two openings on each side. These animals had a diet rich in plant matter and likely evolved to be herbivorous due to the lack of teeth for grazing.
