Parvavis was a tiny bird that lived in China during the Late Cretaceous Period. It was one of the smallest birds of its time, with a wingspan of only about 15 centimeters (6 inches).1

izinto ezimnandi

Iinyani ezimnandi

Parvavis was the first Mesozoic bird ever found in southern China.1 2

When Parvavis was discovered, it was the smallest known enantiornithine bird, even smaller than Iberomesornis.1

The fossil of Parvavis includes parts of the skull, spine, tail, and even impressions of its feathers in the rock.1

Scientists studied the bone structure and found that Parvavis was nearly full-grown when it died, but it was still surprisingly tiny.1 2

Parvavis had a special feature: the bottom joint of its second metatarsal (a foot bone) was wider than the joints of its other metatarsals.1

The claw on the fourth toe of Parvavis was reduced, meaning it was smaller than the other toe claws.1

Umfanekiso owenziwe yi-AI: Parvavis — Umfanekiso owenziwe yi-AI obonisa indlela Parvavis esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Igama lenzululwazi: Parvavis
Inikwe igama ngu:: Wang et al. 20143
Iqela: Iintaka zokuqala
Usapho / iclade: Enantiornithes3
Ukuhlelwa: Theropoda > Avialae3
Ubudala bamatye: 94 ukuya ku-84 izigidi zeminyaka (Turonian / Santonian)3
Izakhiwo zamatye: Jiangdihe3
Amazwe: iTshayina3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: The skeleton of Parvavis was found in 2010 near Luojumei Village in Yunnan, China. It was named and described in 2014 by Wang Min, Zhou Zhonghe, and Xu Guanghui.1
Kusaxoxwa ngayo: Scientists are still debating exactly where Parvavis fits on the enantiornithine family tree. Some analyses place it in a relatively basal position, meaning it may have been an early branch of this group.1
