Prettige feite

Oxalaia is the largest meat-eating dinosaur ever found in Brazil.1

Its teeth had no serrations, unlike many other spinosaurids such as Suchomimus.1

Oxalaia had one functional tooth followed by two replacement teeth, a feature not seen in other theropod dinosaurs.1

The front part of its snout was very expanded and rounded, different from Spinosaurus.1

Oxalaia lived about 100 to 94 million years ago during the Late Cretaceous period.3

Its fossils were found on Cajual Island, a place where descendants of escaped slaves (quilombolas) live.1

julle het gevra

Mees gevraagde vrae oor Oxalaia

?How big was Oxalaia?

Oxalaia was about 12 to 14 metres long and weighed 5 to 7 tonnes. That makes it the largest meat eating dinosaur found in Brazil.1 2

?What did Oxalaia eat?

Oxalaia was a spinosaurid, so it mostly ate fish, like a crocodile. It may also have eaten small dinosaurs and pterosaurs.2

?When did Oxalaia live?

Oxalaia lived during the Late Cretaceous period, about 100.5 to 93.9 million years ago.2

?Where was Oxalaia found?

Oxalaia's fossils were found on Cajual Island in Maranhão, northeastern Brazil, in the Alcântara Formation.2

?Is Oxalaia a dinosaur?

Yes, Oxalaia is a dinosaur. It is a spinosaurid theropod, which means it was a meat-eating dinosaur.2

?Did Oxalaia have feathers?

Nobody knows for sure. No feathers have been found with Oxalaia fossils, and spinosaurids are not known to have feathers, but some related dinosaurs may have had them.2

?Was Oxalaia bigger than T. rex?

Oxalaia was about 12 to 14 metres long, similar in length to T. rex, but T. rex was heavier, weighing about 8 tonnes compared to Oxalaia's 5 to 7 tonnes.1 2

?Could Oxalaia swim?

It is possible. Spinosaurids like Oxalaia had long snouts and conical teeth like fish-eaters, and some scientists think they could swim, but there is no direct evidence for Oxalaia.2

Vir dino-kenners

Wetenskaplike naam: Oxalaia
Benoem deur: Kellner et al. 20113
Groep: Spinosourusse
Familie / klade: Spinosauridae3
Klassifikasie: Theropoda > Spinosauridae3
Ouderdom van die rotse: 100 tot 94 miljoen jaar (Cenomanian)3
Rotsformasies: Alcântara3
Lande: Brasilië3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Oxalaia was named in 2011 by Alexander Kellner and his team based on a snout and a jaw fragment found at Laje do Coringa in Brazil.3 1
Steeds omstrede: Scientists are not sure if Oxalaia is a separate species or the same as Spinosaurus, because only a few bones have been found.1
