Altirhinus kurzanovi

†Altirhinus kurzanovi was an iguanodontian ornithopod from the Early Cretaceous (~125-100 Ma) of Mongolia. About 8m long, it was notable for its distinctive high, arched nasal region — giving it a pronounced 'nose hump.' Named by Norman in 1998 from the Khukhteeg Formation, it was a bipedal/quadrupedal herbivore and one of the larger herbivores of Cretaceous central Asia.

Diet & Feeding

Herbivore

Altirhinus kurzanovi 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

Cretaceous Early Mesozoic Era

Altirhinus kurzanovi lived during the Cretaceous Early period of the Mesozoic Era, approximately 145.0 to 100.5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
