Kol was a small theropod dinosaur that lived during the Late Cretaceous period, approximately 83.6 million years ago in what is now Mongolia. This diminutive predator belonged to the alvarezsaurids, a specialised group of theropods known for their unusual anatomy and likely insectivorous lifestyle.
Standing roughly half a metre tall at the hip and measuring about 1.5 metres in total length, Kol was built for speed and agility. Like other members of its family, it possessed long, powerful legs designed for rapid running across the desert landscapes of ancient Asia. Its body was lightweight yet robust, weighing approximately 20 kilograms, making it well-suited for quick movements and sudden direction changes whilst hunting.
As a carnivore, Kol likely fed primarily on insects, small reptiles, and possibly eggs. Its specialized anatomy suggests it was particularly well-adapted for digging into termite mounds and ant colonies, using its strong forelimbs to break open these structures and access the protein-rich insects within. This ecological niche made Kol an important part of the Late Cretaceous ecosystem.
The fossil remains of Kol were discovered in the famous Ukhaa Tolgod locality in Mongolia's Gobi Desert, an area renowned for its exceptional preservation of small dinosaur fossils. The discovery has provided valuable insights into the diversity and evolution of alvarezsaurid theropods during the Late Cretaceous period.
What made Kol distinctive?
Kol possessed the characteristic alvarezsaurid features of extremely long, powerful hind legs built for running, and relatively short but strong forelimbs. Its small skull housed sharp, pointed teeth ideal for catching insects and small prey.
Behaviour
Kol was likely a swift runner, using its exceptional speed to chase down insects and small animals across the desert terrain. Evidence suggests it may have been social, potentially hunting in small groups to efficiently exploit termite colonies and other concentrated food sources.
Discovery
Kol was first described by Alan Turner and colleagues in 2004. The original fossils were discovered at Ukhaa Tolgod, Gobi Desert, Mongolia.
Kol FAQ
What did Kol eat?
Kol was a carnivore that primarily fed on insects, particularly ants and termites. It may have also eaten small reptiles, mammals, and possibly dinosaur eggs. Its specialised anatomy suggests it was well-adapted for breaking into insect colonies to access the protein-rich prey within.
How big was Kol?
Kol was a small dinosaur, standing about 0.5 metres tall at the hip and measuring approximately 1.5 metres in total length. It weighed around 20 kilograms, making it roughly the size of a large dog but much more lightly built for speed.
When did Kol live?
Kol lived during the
Late Cretaceous period, approximately 83.6 million years ago. This places it in the Campanian stage of the Late Cretaceous, during a time when dinosaurs were at their most diverse.
Where was Kol found?
Kol fossils were discovered in Mongolia, specifically at the Ukhaa Tolgod locality in the Gobi Desert. This area is famous for its exceptional preservation of small dinosaur fossils and has yielded many important discoveries from the
Late Cretaceous period.
How do you pronounce Kol?
Kol is pronounced simply as 'KOHL', rhyming with 'goal' or 'coal'. The name is relatively straightforward compared to many dinosaur names.
What does Kol mean?
The name Kol means 'nimble' or 'quick', which perfectly describes this small theropod's apparent lifestyle and physical adaptations for speed and agility.
How fast could Kol run?
While exact speed estimates are not available, Kol's long leg bones and lightweight build suggest it was built for speed. Its proportions are similar to modern fast-running birds like roadrunners, indicating it could likely achieve impressive speeds for its size.
What type of dinosaur was Kol?
Kol was a theropod dinosaur, specifically belonging to the family Alvarezsauridae. These were specialised small theropods known for their adaptations to an insectivorous lifestyle and exceptional running abilities.
Was Kol related to birds?
Yes, as a theropod dinosaur, Kol was part of the group that includes the ancestors of modern birds. Alvarezsaurids like Kol show several bird-like characteristics, though they represent a separate branch of theropod evolution from the direct bird lineage.
How many Kol fossils have been found?
The fossil record of Kol is relatively limited, with the original discovery consisting of partial skeletal remains. Like many small dinosaurs, Kol's delicate bones were less likely to fossilise than those of larger dinosaurs, making complete specimens rare.
