Utuntu dushimishije

1

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

2

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

3

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

4

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

5

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

6

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

Byakozwe na AIIshusho ya Oxalaia yakozwe na AI
Ishusho yakozwe na AI yerekana uko Oxalaia ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.

Ibibazo bibazwa cyane kuri 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.12

?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.12

?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

Scientists are not sure if Oxalaia is a separate species or the same as Spinosaurus, because only a few bones have been found.1
