Cumnoria prestwichii

† Cumnoria prestwichii is a small iguanodontian dinosaur from the Late Jurassic Kimmeridge Clay of England, known from a well-preserved skeleton. Estimated at approximately 3.5 m in length, it was a biped herbivore browsing on ferns and cycads in coastal lowland habitats. Described by Harry Seeley and originally placed in Iguanodon before being reclassified, it was named in honour of geologist Joseph Prestwich. It remains one of the better-known ornithopods from the Late Jurassic of Britain.

Diet & Feeding

Herbivore

Cumnoria prestwichii was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Jurassic Late Mesozoic Era

Cumnoria prestwichii lived during the Jurassic Late period of the Mesozoic Era, approximately 161.5 to 145.0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
