Prettige feite

Ypupiara was the first dromaeosaurid (raptor) dinosaur ever discovered in South America.1

Its only known fossil was a piece of upper jaw and lower jaw, which was destroyed in a fire at the National Museum of Brazil in 2018.1

Scientists only described and named Ypupiara in 2021, using photographs taken just before the fire.1

Ypupiara's teeth were fluted (had grooves) and lacked serrations, which is unusual for a raptor.2

Its closest relative was Austroraptor, another fish-eating raptor from Argentina.1 2

The name Ypupiara comes from a Tupi word meaning 'the one who lives in the water', referring to a local water spirit.1

Mees gevraagde vrae oor Ypupiara

?How big was Ypupiara?

It was about 2 to 3 metres (6.6 to 9.8 feet) long from the tip of its nose to the end of its tail.4

?What did Ypupiara eat?

It mostly ate fish, using its long, skinny, hook-like teeth to catch them. It may also have eaten lizards and small amphibians.1 4

?When did Ypupiara live?

It lived near the end of the age of dinosaurs, between about 72 million and 66 million years ago.4

Mite-breker

Mite: Ypupiara was a giant raptor like Velociraptor from the movies.

Waarheid: Ypupiara was a small, slender unenlagiine raptor, probably about the size of a turkey or a large dog, and it ate fish, not large prey.1 2

Vir dino-kenners

Wetenskaplike naam: Ypupiara
Benoem deur: Brum et al. 20215
Groep: Raptors
Familie / klade: Dromaeosauridae5
Klassifikasie: Theropoda > Dromaeosauridae5
Ouderdom van die rotse: 72 tot 66 miljoen jaar (Maastrichtian)5
Rotsformasies: Serra da Galga5
Lande: Brasilië5
Fossielrekords: 1 in The Paleobiology Database5
Ontdekking: The fossil was found by Alberto Lopa in the 1950s in Brazil. It was stored at the National Museum of Brazil and only described as a new dinosaur in 2021 by Arthur Brum and colleagues, after the original specimen was lost in a fire.1
Steeds omstrede: Scientists are not sure if another fossil called 'Lopasaurus' (a foot bone) belongs to the same species as Ypupiara, because the two fossils don't overlap in body parts.1
