Claosaurus is an extinct genus of basal hadrosauroid dinosaur that lived in Kansas during the Late Cretaceous period.
Description[]
Traditionally classified as an early member of the family Hadrosauridae, a 2008 analysis found Claosaurus agilis to be outside of the clade containing Hadrosaurus and other hadrosaurids, making it the closest non-hadrosaurid relative of true hadrosaurids within the clade Hadrosauria.
Claosaurus had a slender body and slim feet, with long legs, small arms, and a long, stiff tail. It probably grew to a length of about 3.5 meters and weighed roughly 475 kg. It appears to have walked on its hind legs, dropping to all fours only to graze. Like other hadrosaurs, it was an herbivore. This species is not accepted as representing Claosaurus in reviews of the genus, but has not been given its own genus.
