Prettige feite

Morrosaurus is one of the few dinosaurs known from Antarctica, showing that dinosaurs lived on every continent.1

Its leg bones suggest it was a fast runner, with a slender, tightly bunched foot that helped it sprint.1 3

Morrosaurus belonged to a group called Elasmaria, which also included dinosaurs from Patagonia and Australia, showing they shared a common land connection.3

The only known fossil is a partial right hind leg, including parts of the thigh, shin, and foot.1

It lived in a cool, temperate rainforest with high rainfall, very different from the icy Antarctica we know today.3

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

Mite-breker

Mite: Some people think dinosaurs never lived in Antarctica because it is too cold.

Waarheid: Morrosaurus and other dinosaurs lived in Antarctica when it was warmer and covered in forests, during the Late Cretaceous.1 3

Vir dino-kenners

Wetenskaplike naam: Morrosaurus
Benoem deur: Rozadilla et al. 20164
Groep: Plantvreters met snawels
Familie / klade: Elasmaria4
Klassifikasie: Ornithischia > Ornithopoda > Iguanodontia4
Ouderdom van die rotse: 72 tot 66 miljoen jaar (Maastrichtian)4
Rotsformasies: Snow Hill Island4
Lande: Antarktika4

Ontdekking: The fossil was found in 2002 by Argentine paleontologist Fernando Novas, and the species was named Morrosaurus antarcticus in 2016 by Rozadilla and colleagues.1
Steeds omstrede: Scientists are still debating exactly how Morrosaurus and other southern dinosaurs are related to each other, and whether they formed a single group called Elasmaria.3
