Saurichthys Ultimus
''Saurichthys'' (from el, σαῦρος , 'lizard' and el, ἰχθῦς 'fish') is an extinct genus of predatory Actinopterygii, ray-finned fish from the Triassic period. It type genus family (taxonomy), family Saurichthyidae (Changhsingian-Jurassic, Middle Jurassic), and the largest and longest lasting genus in the family. This family also includes the Permian ''Eosaurichthys'' (China) and the Jurassic ''Saurorhynchus'' (= ''Acidorhynchus'') from Europe and North America, though it may be more appropriate to treat these as subgenera of ''Saurichthys,'' due to the genus ''Saurichthys'' otherwise being paraphyletic.'''' Fossils of ''Saurichthys'' have been found on all continents except South America and Antarctica.''Saurichthys'' at Fossilworks.org It inhabited both marine and freshwater environme ...

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...
