Toretocnemus was a small, fast-swimming marine reptile that lived in the Late Triassic oceans. It had a long snout, big eyes, and flippers like a dolphin, and it hunted fish and other sea creatures.1

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

Toretocnemus means 'perforated tibia' because its shin bone had a hole in it.1

It was first described in 1903 by paleontologist John Campbell Merriam from fossils found in California.1 3

Two species are known: T. californicus and T. zitteli, named after the German paleontologist Karl Alfred von Zittel.1

Toretocnemus was a small ichthyosaur, probably no longer than 2 meters (6.6 feet), and some were only about 1 meter (3.3 feet) long.1

Its fossils have been found in the Hosselkus Limestone in California and the Antimonio Formation in Mexico.1 3

The first fossils were collected by Annie Montague Alexander along the Pit River in Shasta County, California.1

Toretocnemus had three fingers on each flipper, which is unusual for ichthyosaurs.2

Umfanekiso owenziwe yi-AI: Toretocnemus — Umfanekiso owenziwe yi-AI obonisa indlela Toretocnemus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Kwiingcali zeedayinaso

Igama lenzululwazi: Toretocnemus
Inikwe igama ngu:: Merriam 19033
Iqela: Ii-ichthyosauri
Usapho / iclade: Toretocnemidae3
Ukuhlelwa: Ichthyosauria > Ichthyosauromorpha3
Ubudala bamatye: 237 ukuya ku-227 izigidi zeminyaka (Carnian)3
Izakhiwo zamatye: Antimonio, Hosselkus3
Amazwe: iMexico, iUSA3
Iirekhodi zeefosili: 4 kwi-Paleobiology Database3
Ikwaziwa ngokuba: Leptocheirus, Merriamia, Rhachitrema (amagama amadala ngoku abalwa njengesilwanyana esinye)3
Ukufunyanwa: John Campbell Merriam named Toretocnemus in 1903 from fossils found in the Hosselkus Limestone of Shasta County, California, collected by Annie Montague Alexander.1 3
Kusaxoxwa ngayo: Scientists are not sure if Toretocnemus was a strong open-ocean swimmer or stayed near coasts, because its fossils are only found in a small area.1
