An incredible Allosaurus tooth discovery from the Morrison Formation! 🦷 Jason Cooper uncovered two massive Allosaurus teeth with serrated edges and deep roots, along with part of the lower jaw. These fossils reveal how Allosaurus used its sharp teeth to slice through prey and replaced them continuously to maintain a powerful, functional bite. The jaw structure also helps paleontologists study how this Jurassic predator’s feeding mechanics made it a dominant hunter in its ecosystem. 🦖 Don’t try
