Terminonatator

Naam beteken: “last swimmer”1

Het geëet: VleisPlesiosourusseLaat KrytTegnies nie 'n dinosourus nie

Terminonatator was a marine reptile that swam in the shallow sea that once covered Canada. It was a plesiosaur with a long neck and four flippers, and it hunted fish and other sea creatures. This animal lived near the end of the age of dinosaurs, about 80 million years ago.1 3

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

Terminonatator is one of the youngest plesiosaurs known from the Western Interior Seaway, a sea that split North America in two during the dinosaur age.1

The only fossil found is a skull and partial skeleton of a young adult. The skull is about 27 cm (10.6 in) long and had a short snout compared to other elasmosaurids.1

Over 150 pebbles were found inside its rib cage. These gastroliths helped it digest food, just like some modern birds and crocodiles.1

Its thigh bone was longer than its upper arm bone, which is unusual for an elasmosaurid. The right thigh bone had broken and healed while the animal was alive.1

The name Terminonatator means 'last swimmer' because it lived so late in the Cretaceous period, near the end of the age of dinosaurs.1

It had only nine teeth in the tip of its upper jaw, while most other plesiosaurs had ten. This might just be a difference between individuals.1

julle het gevra

Mees gevraagde vrae oor Terminonatator

?How big was Terminonatator?

About 7 metres (23 feet) long, and up to 9 metres (30 feet) if it had an extremely long neck like Elasmosaurus.1

?What did Terminonatator eat?

It ate fish. Its small head and long, thin teeth were good for catching fish, and it probably used its long neck to help capture schooling fish.2

?When did Terminonatator live?

It lived about 70 million years ago, near the end of the Cretaceous period, in a shallow sea that covered Saskatchewan, Canada.2

?Why did Terminonatator swallow stones?

It swallowed stones called gastroliths, which may have helped it digest food or control its buoyancy in the water.2

Vir dino-kenners

Wetenskaplike naam: Terminonatator
Benoem deur: Sato 20033
Groep: Plesiosourusse
Familie / klade: Elasmosauridae3
Klassifikasie: Plesiosauria > Elasmosauridae > Sauropterygia3
Ouderdom van die rotse: 84 tot 72 miljoen jaar (Campanian)3
Rotsformasies: Bearpaw Shale3
Lande: Kanada3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Tamaki Sato named and described Terminonatator in 2003, based on a skull and partial skeleton found high in the Bearpaw Formation near Ponteix, Saskatchewan, Canada. The species name ponteixensis honors the town of Ponteix.1 3
Steeds omstrede: Scientists are not sure exactly how long its neck was. If it had as many neck vertebrae as Elasmosaurus (72), it could have been up to 9 m (30 ft) long.1
