Baptanodon was a dolphin-shaped marine reptile that swam in the warm Jurassic seas. It had a long snout and big eyes to hunt squid and fish. Even though its name means 'toothless', scientists later found tiny teeth in its jaws.1 2

izinto ezimnandi

Iinyani ezimnandi

Baptanodon lived about 160 to 156 million years ago, during the Late Jurassic period.1

Its body was shaped like a dolphin, about 3.5 metres (11 feet) long, and it used its tail to swim fast.1

For many years scientists thought Baptanodon had no teeth, but in 1902 Charles Gilmore found tiny teeth in its jaws.2

Baptanodon was first named Sauranodon in 1879, but that name was already used for another animal, so it was changed to Baptanodon in 1880.1

Fossils of Baptanodon come from the Sundance Formation in Wyoming, which was once a shallow sea.1

Baptanodon is part of the ophthalmosaurid family, a group of ichthyosaurs with very large eyes.1 3

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

ubuzile

Eyona mibuzo ibuzwa kakhulu: Baptanodon

?Was Baptanodon a dinosaur?

No, Baptanodon was an ichthyosaur, a marine reptile that lived in the sea, not a dinosaur.1

?How big was Baptanodon?

About 3.5 metres (11 feet) long, roughly the size of a small dolphin.1

?Did Baptanodon have teeth?

Yes, even though its name means 'toothless', scientists later discovered tiny teeth in its jaws in 1902.1 2

Inyaniso ngeentsomi

Intsomi: Baptanodon had no teeth at all.

Inyaniso: Scientists originally thought it was toothless, but later discovered small teeth in its jaws.1 2

Kwiingcali zeedayinaso

Igama lenzululwazi: Baptanodon
Inikwe igama ngu:: Seeley 18743
Iqela: Ii-ichthyosauri
Usapho / iclade: Ophthalmosauridae3
Ukuhlelwa: Ichthyosauria > Ichthyosauromorpha3
Ubudala bamatye: 168 ukuya ku-155 izigidi zeminyaka (Bathonian / Oxfordian)3
Izakhiwo zamatye: Sundance3
Amazwe: iUSA3
Iirekhodi zeefosili: 2 kwi-Paleobiology Database3
Ikwaziwa ngokuba: Sauranodon (amagama amadala ngoku abalwa njengesilwanyana esinye)3
Ukufunyanwa: Baptanodon was first described by Othniel Charles Marsh in 1879 under the name Sauranodon. In 1880, Marsh renamed it Baptanodon because Sauranodon was already taken.1
Kusaxoxwa ngayo: Scientists still debate whether Baptanodon is a separate genus from Ophthalmosaurus or just a species of that group.1
