Piscivorenantiornis was a tiny bird that lived in China about 120 million years ago. It loved eating fish and could even cough up a pellet of fish bones, just like some birds do today!1 2

izinto ezimnandi

Iinyani ezimnandi

It is the first known fish-eating enantiornithine bird.1

The first fossil was found with a neat pile of fish bones in its stomach area, probably a pellet it was about to spit out.1

Its pelvis (hip bones) was completely fused together, which is rare for early Cretaceous birds. Only a couple of other enantiornithines share this feature.2

The sternum (breastbone) had special prongs at the front that most other enantiornithines lack.1

One of the bones in its neck had a weird shape: it was curved up and down on one side and side to side on the other. No other bird has that.3

A second skeleton of this bird was found in 2020, giving scientists more clues about how it lived.1

It lived during the Aptian age, about 121 to 113 million years ago.4

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