Shastasaurus

O nome significa: “Mount Shasta lizard”1
Comía: CarneIctiosaurosTriásico SuperiorTecnicamente non é un dinosauro

Shastasaurus was a giant marine reptile that swam in the oceans during the Late Triassic, not a dinosaur. Some species were as long as a blue whale, making them among the biggest reptiles that ever lived. It had a very short, toothless snout, unlike most other ichthyosaurs.1

Dato curioso: este réptil mariño nadaba mentres os dinosauros camiñaban por terra. Todo o mundo lles chama dinos, pero eran outra rama dos réptiles.

Datos curiosos

1

Shastasaurus lived about 235 to 205 million years ago, during the Late Triassic period.1

2

The largest species, Shastasaurus sikanniensis, could reach 21 metres (69 feet) long and weigh over 80 tonnes, as heavy as a large whale.1

3

Unlike most ichthyosaurs, which had long snouts full of teeth, Shastasaurus had a very short, toothless beak.1

4

Scientists think Shastasaurus may have been a suction feeder, sucking in soft prey like squid, similar to some modern beaked whales.1

5

The name Shastasaurus comes from Mount Shasta in California, near where the first fossils were found.1

6

Shastasaurus had a very slender body. One species had a ribcage less than 2 metres deep even though its flippers were 7 metres apart.1

7

It is not known if Shastasaurus had a dorsal fin, but earlier ichthyosaurs like Mixosaurus did have one.1
