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.
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 Texas and Oklahoma red beds are sedimentary rocks, mostly consisting of sandstone and red mudstone. [8] The red color of the rocks is due to the presence of ferric oxide . [ 9 ] The rocks were deposited during the early Permian in a warm, moist climate, [ 10 ] with seasonal periods of dry conditions.
Shaded relief map of the Llano Estacado. Texas contains a wide variety of geologic settings. The state's stratigraphy has been largely influenced by marine transgressive-regressive cycles during the Phanerozoic, with a lesser but still significant contribution from late Cenozoic tectonic activity, as well as the remnants of a Paleozoic mountain range.
One of the coolest, most prehistoric-looking fish lives in Florida’s offshore waters of the Gulf of Mexico. It happens to be one of the best to eat but also one of the most elusive.
The Columbian mammoth was a herbivore, with a diet consisting of varied plant life ranging from grasses to conifers. [4] At this time, the Central Texas landscape consisted of temperate grasslands and savannahs surrounded by river floodplains. [5] How the animals at the site died is unknown, but there is no evidence that humans were involved.
On land, North America's vegetation included plants like conifers, cycads, ferns, ginkgoes, and horsetails. [46] The Triassic vegetation of the east coast indicated swampy conditions in the local rift valleys. Arizona was home to a great forest that would later leave behind the area's famous petrified wood. [51]
