Prettige feite

Pycnonemosaurus is the largest formally described abelisaurid, with later estimates reaching about 8.9 metres (29.2 ft) long.1

Its bones were found in red conglomeratic sandstone, and the surface was abraded, meaning the bones were partly exposed before being collected.1

The only known skeleton is incomplete, including five teeth, parts of seven tail vertebrae, a right pubis, a right tibia, and part of a right fibula.1 2

It had a small pubic foot and a hatchet-shaped cnemial crest on its tibia, which are unique features among abelisaurs.1 2

The specimen is thought to be from an immature individual, probably a subadult, so adults might have been even larger.1

Its tail vertebrae have fan-shaped transverse processes and forward projections, typical of abelisaurids, but these projections become smaller towards the end of the tail.1

julle het gevra

Mees gevraagde vrae oor Pycnonemosaurus

?How big was Pycnonemosaurus?

It was about 8.9 metres long and weighed around 3.6 tonnes. That makes it the largest formally described abelisaurid.1

?What did Pycnonemosaurus eat?

It was a predator that probably ate titanosaurs, which were huge long-necked dinosaurs found in the same area. Its small, sharp teeth helped it grip struggling prey.1

?Where was Pycnonemosaurus found?

Its bones were found in Brazil, in the state of Mato Grosso, in red conglomeratic sandstone of the Cachoeira do Bom Jardim Formation.1

?When did Pycnonemosaurus live?

It lived during the Late Cretaceous, about 72 million years ago, in the late Campanian to early Maastrichtian stages.1

?Was Pycnonemosaurus a dinosaur?

Yes, it was a carnivorous theropod dinosaur, part of the group Abelisauridae.1

?Is Pycnonemosaurus bigger than Carnotaurus?

Yes, Pycnonemosaurus was larger. It reached about 8.9 metres long, while Carnotaurus was about 7.8 metres long.3

Mite-breker

Mite: Pycnonemosaurus was a small dinosaur.

Waarheid: It was actually one of the largest abelisaurids, with length estimates up to 9 metres (29.5 ft) and weight up to 3.6 tonnes (4.0 short tons).1

Vir dino-kenners

Wetenskaplike naam: Pycnonemosaurus
Benoem deur: Kellner and Campos 20024
Groep: Vleisvretende dino's
Familie / klade: Abelisauridae4
Klassifikasie: Theropoda > Ceratosauria > Abelisauridae4
Ouderdom van die rotse: 100 tot 66 miljoen jaar (Cenomanian / Maastrichtian)4
Lande: Brasilië4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: The fossils were collected in 1952 to 1953 by Llewellyn Ivor Price at a farm called Roncador in Mato Grosso, Brazil. The species was named by Kellner and Campos in 2002.1 4
Steeds omstrede: Scientists are not sure about its exact size because the only skeleton is incomplete and from a young individual, so estimates range from 6 to 9 metres long.1
