Chacaicosaurus

Naam beteken: “Chacaico lizard, named after the Chacaico Sur locality”1

Het geëet: VleisIgtiosourusseMiddel-JuraTegnies nie 'n dinosourus nie

Chacaicosaurus was a fast-swimming marine reptile that lived in the ocean during the Jurassic Period. It had a very long snout and big eyes to spot its prey. Even though it looked like a fish, it was a reptile that breathed air and gave birth to live babies underwater.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

Chacaicosaurus had a very long snout that made up 80% of its skull length.1

It had unique rounded ridges running along each side of its snout, which no other ichthyosaur has.1

Adult Chacaicosaurus may have had very small teeth or even no teeth at all.1

The only known fossil of Chacaicosaurus was found in 1990 by a team led by Zulma Gasparini.1

Chacaicosaurus lived about 170 to 168 million years ago, during the early Bajocian stage of the Jurassic.1

Its name comes from the Chacaico Sur locality and the Greek word for lizard, while the species name cayi honors the Mapuche sea god Cay.1

Chacaicosaurus shared its ocean home with another ichthyosaur called Mollesaurus and a plesiosaur named Maresaurus.1

KI-prent van Chacaicosaurus — 'n KI-prent van hoe Chacaicosaurus dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.
