吃：肉早期鳥類白堊紀晚期

Gurilynia was a big, ancient bird that lived in Mongolia near the end of the Age of Dinosaurs. It was one of the largest birds of its time, about the size of a modern chicken but much heavier. It flew over dry plains and hunted for food.1

酷東西

趣味知識

Gurilynia is known from only three partial bones: the top end of a right upper arm bone, the bottom end of a left upper arm bone, and the shoulder end of a left coracoid.1

It was the largest bird ever found from the Cretaceous period in Mongolia, weighing about 2.1 kilograms (4.6 pounds).1

The head of its upper arm bone was about 29 millimeters (1.1 inches) wide, much bigger than that of Pengornis, the largest Early Cretaceous enantiornithine.1

Gurilynia belonged to a group of ancient birds called enantiornithines, which had teeth and claws on their wings.1

It lived between 70 and 66 million years ago, right before the mass extinction that wiped out the non-avian dinosaurs.1

The fossils were found in the Nemegt Formation, which was a wet floodplain with rivers and forests during the Late Cretaceous.1

發現: Gurilynia was named by Russian paleontologist Evgeny Kurochkin in 1999, based on fossils collected from the Gurilyn Tsav locality in Mongolia. The species name nessovi honors a colleague.1 2
仍有爭議: Scientists are not sure exactly how big Gurilynia was because only a few bone fragments have been found. The size estimates might change if more complete fossils are discovered.1
