Сонирхолтой баримтууд
Yungavolucris is known only from a few foot bones, called tarsometatarsals. The most complete one is just over 4 centimeters (1.5 inches) long.1
Its foot bones were very wide, about twice as wide as those of its relatives Lectavis and Soroavisaurus, which lived at the same time and place.1
The outer toe bone (metatarsal IV) was very thin but as long as the middle toe bone, and the middle toe bone was bent outward, which is unusual.1
If its legs were short and wide, Yungavolucris might have been a slow, heavy bird that could not fly, about the size of a large chicken.1
Yungavolucris lived alongside other enantiornithean birds like Lectavis and Soroavisaurus, but it had much stouter feet than them.1

- Scientists are not sure how Yungavolucris is related to other enantiornithean birds. Some studies place it close to avisaurids, but others do not, and it might even be the same species as another bird from the same site.1
