Crocodilia. Definition. noun. ( taxonomy) A taxonomic order that includes the crocodilian species. Supplement. The order Crocodilia is comprised of all crocodilian species, such as true crocodile s, alligator s, true gharials, false gharials, and caimans. They appeared in the Late Cretaceous period, therefore, around 83.5 million years ago. The research group composed of Curator Junki Yoshida of Fukushima Prefectural Museum, Professor Yoshitsugu Kobayashi of Hokkaido University Museum, Chief Yuji Takakuwa of Gunma Museum of Natural History Geology Research Section, and others revealed that a new species of Goniopholis, a close relative of the crocodile, was found in the Late Jurassic strata dating to about 155 million years ago James P. Ross Heinz Fritz Wermuth. Crocodile - Evolution, Classification, Adaptations: The most primitive representatives of the crocodilian group occur in the Late Triassic Epoch. Taxonomy is based primarily by the anatomical peculiarities of their skulls. Order Crocodylia (Crocodilia) has four suborders: three are extinct, and the living Chrome は Google が開発した高速、安全でカスタマイズ可能な公式ウェブブラウザです。いますぐダウンロードして自分好みにカスタマイズし Crocodilia (or Crocodylia, both / k r ɒ k ə ˈ d ɪ l i ə /) is an order of mostly large, predatory, semiaquatic reptiles known as crocodilians.They first appeared 94 million years ago in the Late Cretaceous period (Cenomanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria.Members of the order's total group, the clade Crocodylia. Croc­o­dil­ians, along with birds, are the only sur­vivors of the once-preva­lent Ar­chosauria. Dur­ing the Meso­zoic (245-65 mil­lion years ago) this group, in­clud­ing di­nosaurs and other rep­tiles, dom­i­nated life on all con­ti­nents and in the oceans.
