Gnathomortis was a huge marine lizard that swam in the seas of Colorado 80 million years ago. It had powerful jaws and sharp teeth to catch fish and other sea creatures. This ancient predator was one of the biggest mosasaurs of its time.1 2

izinto ezimnandi

Iinyani ezimnandi

Gnathomortis was originally thought to be a species of Prognathodon, but scientists later gave it its own genus in 2020.1 3

Its name means 'jaws of death' because of its powerful bite.1

This marine lizard lived during the Campanian stage of the Late Cretaceous, about 80 to 72 million years ago.2

Gnathomortis reached about 10.5 meters (34 feet) in length, making it one of the larger mosasaurs.1

The only known fossil of Gnathomortis includes a partial skull and backbone, which helped scientists identify it as a new genus.1 3

It had a unique quadrate bone in its skull that was different from other mosasaurs, which helped scientists classify it.3

Umfanekiso owenziwe yi-AI: Gnathomortis — Umfanekiso owenziwe yi-AI obonisa indlela Gnathomortis 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: Gnathomortis
Inikwe igama ngu:: Lively 20204
Iqela: Iimosasauri
Usapho / iclade: Mosasauridae4
Ukuhlelwa: Mosasauroidea4
Ubudala bamatye: 84 ukuya ku-72 izigidi zeminyaka (Campanian)4
Izakhiwo zamatye: Mancos Shale4
Amazwe: iUSA4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: The first fossil of Gnathomortis was found in 1975 in the Mancos Shale of western Colorado. It was originally named Prognathodon stadtmani in 1999, but in 2020 scientist Joshua Lively gave it the new name Gnathomortis after more bones were prepared.1 3
Kusaxoxwa ngayo: Scientists are not sure exactly where Gnathomortis fits in the mosasaur family tree. Some studies place it as a close relative of Globidens, while others think it is more primitive.3
