Did you know more than half of each T. rex tooth was embedded deep in the jaws? This helped the fierce predator withstand the immense bending forces during a bite. While humans replace teeth just once in a lifetime, tyrannosaurs kept getting new teeth about every two years for their entire lives. So they never became toothless and always had sharp new additions. Another fun fact? Unlike lions, T. rex didn’t have big fangs in front: a lion’s fangs are well-placed to stab and grab, while the biggest teeth on T. rex were well-placed to crush bone. #AMNH150
