Callawayasaurus

Naam beteken: “Callaway's lizard”1
Het geëet: VleisPlesiosourusseVroeë KrytTegnies nie 'n dinosourus nie

Callawayasaurus was a long-necked marine reptile that swam in the seas of what is now Colombia. It was not a dinosaur, but a plesiosaur with a small head and a very long neck. It used its four flippers to paddle through the water.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

1

Callawayasaurus had a skull only 35 centimetres (1 foot 2 inches) long, but its whole body was about 7 to 8 metres (24 to 26 feet) long.1

2

Its neck contained 56 vertebrae, which is a lot, but they were shorter than the neck bones of other elasmosaurids.1

3

The nostrils of Callawayasaurus were long and positioned above the upper jaw bone, which had 3 to 5 teeth.1

4

It lived during the Early Cretaceous period, about 125 to 112 million years ago.1

5

The first fossils were found in the Paja Formation near Villa de Leyva, Colombia.1

6

A second, nearly complete skeleton was slightly more robust than the first, which might mean males and females looked a bit different.1

7

Callawayasaurus was named after paleontologist Jack M. Callaway, who studied ancient marine reptiles.1

The first fossil was described by Samuel Paul Welles in 1962, who called it Alzadasaurus colombiensis. In 1999, Kenneth Carpenter moved it to its own genus, Callawayasaurus.1
Steeds omstrede
Scientists are not sure if the slightly more robust skeleton is a different species or just a male or female of the same species.1
