When the city was overgrown by prehistoric plants in the movie "A Sound of Thunder" (2002), Baboonlizards came out of dark places. They appear to be carnivores as they ate one of the crew members. Baboonlizards live in groups as they hunt for prey. They sleep upside down on ceilings like bats. Characteristic of the baboon lizard is his terrifying shriek. As the name suggests, they appear to have primate characteristics.
