Perilous Point was discovered by Al Flemming, Debi Fleming, and Stephanie Maze-Hsu while taking a break from excavating at a neighboring site. They spotted some Triceratops lower jaw fragments. The team, led by Tom Tucker, went back to the locality and discovered that they had found a partially articulated Triceratops skeleton. In 2008 the team collected a complete lower jaw (dentary, angular, surangular, predentary, etc.), several Triceratops teeth, the syncervical, as well as several cervical ribs. They also uncovered an articulated by badly weathered skull, and several articulated dorsal vertebrae and ribs with the scapula still in place.
