Plesiopleurodon

Naam beteken: “near side tooth”1

Het geëet: VleisPlesiosourusseLaat KrytTegnies nie 'n dinosourus nie

Plesiopleurodon was a marine reptile that swam in the warm seas of North America during the time of the dinosaurs. It had a short neck, a long snout, and a mouth full of sharp, pointy teeth. It used its four flippers to paddle through the water like a sea turtle.1

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

Plesiopleurodon is known from just one partial skeleton, including a complete skull that is 71.2 cm long.1

Its name means 'near side tooth' because its teeth look a lot like the teeth of the similar pliosaur Liopleurodon.1

Scientists first thought Plesiopleurodon was a pliosaur, but later studies showed it is actually a polycotylid, a type of short-necked plesiosaur.1

It lived around 100 to 94 million years ago, during the early part of the Late Cretaceous Period.2

Plesiopleurodon's front teeth were large and pointed forward, which helped it grab slippery prey.1

julle het gevra

Mees gevraagde vrae oor Plesiopleurodon

?Was Plesiopleurodon a dinosaur?

No, it was a marine reptile called a plesiosaur, not a dinosaur. It lived in the sea during the time of the dinosaurs.1 3

?How big was Plesiopleurodon?

Scientists are not sure of its total length because only one partial skeleton has been found. Its skull is 71.2 cm long.1 4

?What did Plesiopleurodon eat?

It was a carnivore that ate fish and other marine animals. Its sharp, forward-pointing teeth helped it grab slippery prey.1 3

?When did Plesiopleurodon live?

It lived during the Late Cretaceous Period, about 100 to 94 million years ago.1 4

Mite-breker

Mite: Plesiopleurodon was a dinosaur.

Waarheid: Plesiopleurodon was a plesiosaur, a marine reptile that lived in the sea. It was not a dinosaur, even though it lived at the same time.1

Vir dino-kenners

Wetenskaplike naam: Plesiopleurodon
Benoem deur: Carpenter 19964
Groep: Plesiosourusse
Familie / klade: Polycotylidae4
Klassifikasie: Plesiosauria > Sauropterygia4
Ouderdom van die rotse: 100 tot 94 miljoen jaar (Cenomanian)4
Rotsformasies: 'Hailey Shales'4
Lande: VSA4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: Plesiopleurodon was named by paleontologist Kenneth Carpenter in 1996. He based it on a skull, neck bones, and shoulder bones found in Wyoming, USA.4 1
Steeds omstrede: Scientists are still not sure whether the only known fossil of Plesiopleurodon came from the Belle Fourche Shale or the Hailey Shales Formation, because the original records disagree.1
