Cumnoria

Cumnoria is a genus of basal iguanodontian dinosaur that lived during the Late Jurassic period (Kimmeridgian age) in what is now Oxfordshire, United Kingdom.

==Description== thumb|left|Life reconstruction The holotype of Cumnoria is a rather small bipedal animal with a slender build, about 3.5 metres (11.4 feet) long. The specimen is a juvenile due to the general lack of fusion among all of its vertebrae and ribs. It can be distinguished from all other iguanodontians by the presence of a prominent ridge on the sternal process of the coracoid and an oval muscle scar on the front of the deltopectoral crest of the humerus. Uniquely among non-hadrosauriforms, the ventral and dorsal margins of the scapula only moderately diverge from each other, and there is no defined cingulum on the dentary teeth.
