Palmulasaurus was a fast-swimming marine reptile that lived in the warm seas of Utah about 93 million years ago. It had a long neck and four flippers to paddle through the water. Even though it looked like a dinosaur, it was actually a plesiosaur, a different kind of ancient reptile.1 3

Utuntu dushimishije

Palmulasaurus was first called Palmula, but that name was already used for a tiny fossil shell. Scientists had to give it a new name.1

It lived during the Turonian stage, about 94 to 89 million years ago.1 3

Palmulasaurus belonged to a group of plesiosaurs called polycotylids, which had short necks and were fast swimmers.1

Its fossils were found in the Tropic Shale in Utah, which was once a warm, shallow sea.1 3

Palmulasaurus gave birth to live young, not eggs, like many other marine reptiles.2

Ishusho ya Palmulasaurus yakozwe na AI — Ishusho yakozwe na AI yerekana uko Palmulasaurus ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.

Ivumburwa: Palmulasaurus was named by L. B. Albright, D. D. Gillette, and A. L. Titus in 2007. They originally called it Palmula, but that name was already taken by a foraminiferan, so they changed it to Palmulasaurus.1 3
Biracyagibwaho impaka: Scientists are not sure exactly how big Palmulasaurus grew, because only a few fossils have been found.1
