the prey was trapped, the predators would move in for an easy kill, and
feast. The predators often made a quick and viscous death to the helplessly
trapped prey. There was usually not much left of the prey when the predators
were finished. But the predators were not immune to the trap which they
employed to catch their prey. The predators spent much more time in the
tar pits eating their prey, and were often the victim of their own intelligence.
Fossils of predators make up 90% of the mammals found at La Brea.
