This list of the Paleozoic life of Texas contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Texas and are between 538.8 and 252.17 million years of age.
The prehistoric bony fish of Texas are known largely from Cretaceous rocks. Fossils include mostly teeth, vertebrae, and scales, although sometimes well preserved skeletons are found in the Austin Chalk member. [6] During the Turonian Texas was home to the fish Pachyrhizodus leptopsis. [15] Early Cretaceous heart urchins and biscuit urchins.
Ptychodus was a large shark, previously estimated at 10 meters (33 feet) long based on extrapolation from teeth. [ 13 ] [ 14 ] The subadult specimen with the largest vertebra showed that it could reach lengths of 4.3–7.07 m (14.1–23.2 ft), so a 10 m (33 ft) length is possible, but more analysis is required for verification.
The monstrous predator — which measured as long as a great white shark — belongs to a brand new species, according to a Dec. 12 University of Cincinnati news release.
