Grendelius

Naam beteken: “Grendel's creature, after the monster in the Old English poem Beowulf”1

Het geëet: VleisIgtiosourusseLaat Jura tot Vroeë KrytTegnies nie 'n dinosourus nie

Grendelius was a fast-swimming marine reptile that lived in the Jurassic seas. It was not a dinosaur, but a type of ichthyosaur, which means 'fish lizard'. With its big eyes and sharp teeth, it was a fierce hunter of fish and squid.1 4

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

Grendelius was first described in 1976 from a fossil found in the Kimmeridge Clay of England.1

Its name comes from Grendel, the monster in the Old English poem Beowulf.1

Grendelius had a very short and wide front flipper, which helped it steer quickly through the water.2

Scientists think Grendelius gave birth to live young, like other ichthyosaurs, instead of laying eggs.2

Some experts believe Grendelius might be the same animal as Brachypterygius extremus, but others disagree.2

Fossils of Grendelius have been found in both England and Russia, showing it lived across a wide area of the Jurassic ocean.1 4
