Pycnonemosaurus was a big meat-eating dinosaur with sharp teeth and strong legs. It lived in what is now Brazil, about 72 million years ago. It was one of the largest abelisaurids, a group of short-snouted predators.1

izinto ezimnandi

Iinyani ezimnandi

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

ubuzile

Eyona mibuzo ibuzwa kakhulu: 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

Inyaniso ngeentsomi

Intsomi: Pycnonemosaurus was a small dinosaur.

Inyaniso: 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

Kwiingcali zeedayinaso

Igama lenzululwazi: Pycnonemosaurus
Inikwe igama ngu:: Kellner and Campos 20024
Iqela: Iidayinaso ezitya inyama
Usapho / iclade: Abelisauridae4
Ukuhlelwa: Theropoda > Ceratosauria > Abelisauridae4
Ubudala bamatye: 100 ukuya ku-66 izigidi zeminyaka (Cenomanian / Maastrichtian)4
Amazwe: iBrazil4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: 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
Kusaxoxwa ngayo: 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
