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

ເລື່ອງເທ່ໆ

ເລື່ອງໜ້າຮູ້ມ່ວນໆ

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

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

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

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

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

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

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