Fight for Survival

Fossils can reveal how animals lived and died and what their environment was like. Evidence from one of the park's nimravid fossils offers crime-scene clues: the size and location of holes in the forehead match the knife-like teeth of another large nimravid. Bite marks show evidence of an attack by another nimravid. Nimravids, including Nimravus, resembled large saber-tooth cats but belonged to a different family that is now extinct.
