Acuetzpalin

Naam beteken: “water lizard in Classical Nahuatl”1

Het geëet: VleisIgtiosourusseLaat JuraTegnies nie 'n dinosourus nie

Acuetzpalin was a fast-swimming marine reptile that lived in the warm seas of Mexico during the Late Jurassic. It looked a bit like a dolphin but was actually an ichthyosaur, a group of ocean predators. Its long snout was full of sharp teeth for catching fish and squid.3 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

Acuetzpalin was named in 2020, making it the first new ichthyosaur genus described since 2017.1

Its skull was very well preserved, even though the rest of the skeleton was missing some parts.1

Acuetzpalin belonged to a group called ophthalmosaurids, which were the most advanced ichthyosaurs.2

It lived about 150 million years ago during the Kimmeridgian stage of the Jurassic.3

The fossils were found in the La Casita Formation, which was once a shallow sea.1 2

Acuetzpalin is only known from one partial skeleton, so scientists are still learning about it.1

KI-prent van Acuetzpalin — 'n KI-prent van hoe Acuetzpalin 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.

Vir dino-kenners

Wetenskaplike naam: Acuetzpalin
Benoem deur: Barrientos-Lara and Alvarado-Ortega 20203
Groep: Igtiosourusse
Familie / klade: Ophthalmosauridae3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 155 tot 149 miljoen jaar (Kimmeridgian)3
Rotsformasies: La Casita3
Lande: Meksiko3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Acuetzpalin was discovered by students from the National Autonomous University of Mexico in 1979 and 1980, led by professors Oscar Carranza Castañeda and René Hernández Rivera. It was named and described by Jair Israel Barrientos-Lara and Jesús Alvarado-Ortega in 2020.2 3
Steeds omstrede: Scientists are not sure exactly how big Acuetzpalin grew, because the only known skeleton is missing its tail and limbs.1
