Yungavolucris was a small bird that lived about 70 to 66 million years ago, during the time of the dinosaurs. It had very short, wide feet, which made it look different from most other birds of its time.1

ደስ ዝብሉ ሓቅታት

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

Maybe not. If its legs were both short and wide, it might have been a heavy, sluggish bird that could not fly, like a large chicken.1
