Archeologists found skeletal remains of a 260-million-year-old, dog-sized, short-snouted, saber-toothed leaf-cruncher. There are no serrations on the mammal-like reptile’s teeth so they’re calling it Tiarajudens eccentricus, “unusual tooth.” The weirdo beasts’ 5 inch fangs weren’t used for chewing but for sparing with each other over ferns, leaves, stems and Tiarajudens eccentricus pussy. Nature.
