Caenagnathasia was a tiny, feathered dinosaur that looked a bit like a bird. It had a beak and long legs, and it was one of the smallest dinosaurs ever found. It lived in Asia during the Late Cretaceous period.1

izinto ezimnandi

Iinyani ezimnandi

Caenagnathasia is the smallest known oviraptorosaur and one of the smallest non-avian dinosaurs. Its skull was only about 7.6 centimetres (3 inches) long.1

It lived about 90 million years ago, making it the oldest known caenagnathoid.1

The first fossils were just two fused lower jaw bones, found in Uzbekistan.1

Scientists think it was feathered, like other oviraptorosaurs, and looked bird-like with a beak and long neck.1

In 2015, new bones were found, including vertebrae, a dentary, and a femur, which helped confirm it belonged to the Caenagnathidae family.1

The name honors Gerbert Genrikhovich Martinson, a scientist, in the species name martinsoni.1

Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Caenagnathasia

?How big was Caenagnathasia?

It was tiny. About 0.6 metres (2 feet) long and weighed around 1.4 kilograms (3 pounds). Its skull was only about 7.6 centimetres (3 inches) long.1

?What did Caenagnathasia eat?

Scientists think it ate plants or small animals, because it had a beak and a special shelf in its mouth for grinding food, like other oviraptorosaurs.1 2

?Did Caenagnathasia have feathers?

Yes. It was a feathered dinosaur, like other oviraptorosaurs, and looked bird-like with a beak and long neck.1

?When did Caenagnathasia live?

It lived about 90 million years ago, during the Late Cretaceous period. It is the oldest known caenagnathoid.1

Inyaniso ngeentsomi

Intsomi: Some people think Caenagnathasia was a bird because it had a beak and feathers.

Inyaniso: It was a dinosaur, not a bird. It belonged to a group of feathered theropods called oviraptorosaurs, which are closely related to birds but not birds themselves.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Caenagnathasia
Inikwe igama ngu:: Currie et al. 19943
Iqela: Iidayinaso ezingaqhelekanga ezineentsiba
Usapho / iclade: Caenagnathidae3
Ukuhlelwa: Theropoda > Oviraptorosauria3
Ubudala bamatye: 94 ukuya ku-72 izigidi zeminyaka (Turonian / Campanian)3
Izakhiwo zamatye: Bissekty, Iren Dabasu3
Amazwe: iUzbekistan, iTshayina3
Iirekhodi zeefosili: 7 kwi-Paleobiology Database3
Ukufunyanwa: Caenagnathasia was named in 1994 by Philip J. Currie, Stephen Godfrey, and Lev Nessov. The first fossils were found near Dzharakuduk in Uzbekistan, in the Bissekty Formation.1
Kusaxoxwa ngayo: Scientists are still debating exactly where Caenagnathasia sits in the dinosaur family tree. Some think it was a primitive member of the Caenagnathidae, while others suggest it might be more basal within Oviraptorosauria.1
