Trinacromerum

Igama lithetha: “three tipped femur”1

Yayitya: InyamaIiplesiosauriiCretaceous yokuqala ukuya ku-iCretaceous yamvaNgokwenene ayisiyo dayinaso

Trinacromerum was a fast-swimming marine reptile that lived in the Late Cretaceous seas. It used its long flippers like paddles to chase small fish. Even though it looked a bit like a dolphin, it was actually a plesiosaur, not a dinosaur.1 4

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

izinto ezimnandi

Iinyani ezimnandi

Trinacromerum's long flippers helped it swim very fast, and scientists think it moved like a 'four-flippered penguin'.1

Its name means 'three tipped femur', which refers to a bone in its hip that had three points.1

Trinacromerum had 46 vertebrae in its spine, including 20 in the neck, 3 in the chest, and 23 in the back.2

Fossils of Trinacromerum have been found in rocks that were once the bottom of a shallow sea that covered central North America.4

It lived from about 106 to 66 million years ago, during the Late Cretaceous period.4

Some scientists once thought Trinacromerum was the same as another plesiosaur called Dolichorhynchops, but now they are considered different.2

Umfanekiso owenziwe yi-AI: Trinacromerum — Umfanekiso owenziwe yi-AI obonisa indlela Trinacromerum 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: Trinacromerum

?How big was Trinacromerum?

About 3 meters (9.8 feet) long. That is roughly the length of a small car.1 3

?What did Trinacromerum eat?

It ate small fish. Its teeth were shaped for catching and holding slippery prey.1 3

?Could Trinacromerum swim fast?

Yes, its long flippers helped it swim very fast. Scientists compare its swimming style to a 'four-flippered penguin.'1 3

?Is Trinacromerum a dinosaur?

No, it is a plesiosaur, which is a marine reptile. It lived in the sea and was not a dinosaur.1 3

Inyaniso ngeentsomi

Intsomi: Some people think Trinacromerum was a dinosaur because it lived in the sea and had flippers.

Inyaniso: Trinacromerum was a plesiosaur, a marine reptile, not a dinosaur. Dinosaurs lived on land and had different body shapes.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Trinacromerum
Inikwe igama ngu:: Cragin 18884
Iqela: Iiplesiosauri
Usapho / iclade: Polycotylidae4
Ukuhlelwa: Plesiosauria > Sauropterygia4
Ubudala bamatye: 106 ukuya ku-66 izigidi zeminyaka (Albian / Maastrichtian)4
Izakhiwo zamatye: Carlile Shale, Greenhorn Limestone, Pierre Shale4
Amazwe: iUSA, iKhanada4
Iirekhodi zeefosili: 18 kwi-Paleobiology Database4
Ukufunyanwa: Trinacromerum was first named by Francis W. Cragin in 1888 from fossils found in Kansas, USA. Later, more fossils were found in Canada and other parts of the USA.1 4
Kusaxoxwa ngayo: Scientists still debate whether some fossils belong to Trinacromerum or to its close relative Dolichorhynchops, because their skeletons are very similar.2
