Evgenavis was a small, bird-like dinosaur that lived during the Early Cretaceous period. It had strong legs and sharp claws, and it probably hunted for food on the ground.3 2

izinto ezimnandi

Iinyani ezimnandi

Evgenavis is known only from a single fossil bone, a tarsometatarsus (a foot bone).1 2

Scientists are not sure exactly what group Evgenavis belongs to. It might be a confuciusornithiform (like the early beaked bird Confuciusornis) or an enantiornithine (a different group of early birds).1 2

The fossil of Evgenavis was found in 2007 by a joint expedition from the Zoological Institute, Tomsk University, and Saint Petersburg University.2

Evgenavis lived during the Early Cretaceous, about 125 to 113 million years ago.3

The name Evgenavis honors Evgeny Kurochkin, a famous Russian paleontologist who studied ancient birds.1

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

Ukufunyanwa: Evgenavis was named in 2014 by Jingmai O'Connor, Alexander Averianov, and Nikita Zelenkov. The only fossil, a foot bone, was found at the Shestakovo-3 site in western Siberia.3 2
Kusaxoxwa ngayo: Scientists still debate whether Evgenavis was a confuciusornithiform or an enantiornithine bird. More fossils are needed to be sure.1 2
