名字的意思： “foot”1

吃：肉肉食恐龍白堊紀晚期

Kol was a fast-running, meat-eating dinosaur that lived in what is now Mongolia about 75 million years ago. It is known from just one complete foot, which tells us it was a speedy hunter about twice the size of its relative Shuvuuia.1

酷東西

趣味知識

Kol is known from only one complete right foot, which is unusual because its relative Shuvuuia is known from many skeletons.1

The foot bones of Kol show an extreme arctometatarsalian condition, where the middle metatarsal is pinched between the outer bones, an adaptation for fast running.1

Kol lived about 75 million years ago during the Late Cretaceous period.1

The name Kol means 'foot' in Mongolian, and ghuva means 'beautiful', so the full name means 'beautiful foot'.1

Kol was one of the largest members of the alvarezsaurid group, estimated at 1.8 to 2.4 meters (5.9 to 7.9 feet) long and 20 to 24 kilograms (44 to 53 pounds).1

Some scientists think Kol might not be an alvarezsaurid but instead related to Avimimus within the oviraptorosaurs, but this is still debated.1

給恐龍專家

學名: Kol
命名者: Turner et al. 20092
類群: 肉食恐龍
科 / 演化支: Coelurosauria2
分類: Theropoda2
岩石的年代: 84 到 72 百萬年 (Campanian)2
岩層: Djadokhta2
國家: 蒙古2
化石紀錄: The Paleobiology Database 收錄 1 筆2
發現: Kol was named by Alan H. Turner, Sterling J. Nesbitt, and Mark A. Norell in 2009 based on a single foot (specimen IGM 100/2011) found at Ukhaa Tolgod in Mongolia.2 1
仍有爭議: Scientists are not sure whether Kol belongs to the alvarezsaurids or to the oviraptorosaurs, because the only known fossil is a foot.1
