Altirhinus Iguanodon Skull cast replica

Altirhinus Iguanodon orientalis skull Iguanodon means "Iguana tooth". It is classified as: Ornithopoda; Iguanodontia; Iguanodontidae Early Cretaceous (Aptian), Barum Bayan Formation Discovered in the Gobi Desert, Southwestern Mongolian Peoples' Republic. Its hands had four fingers and a spike-like thumb, which it may have used to defend itself. Its teeth are reminiscent of those in hypsilophodonts, flattened side to side, and leaf-shaped. They probably sliced up plant material like a pair of scissors. Because of the large number of skeletons of these dinosaurs frequently found together and evidence from fossil trackways, paleontologists think they may have formed herds. Their remains are most often found in sediments deposited in swampy, lake, and river edge environments suggesting that is the place they spent most of their time munching on horsetails (like the living Equisetum), ferns, cycads, and various kinds of conifers. Iguanodon orientalis from Mongolia (above) is very similar to iguanodonts from Europe (below) except for its huge, bulbous 'nose.' This hollow structure may have been used as a resonating chamber for making 'dinosaur music or mating calls. This skull measures 90cm in length Cast in resin. $975 This item is not kept in stock.

Though similar in overall anatomy, this Mongolian species is most distinguished by its large, bulbous nasal structure—a hollow chamber that may have served as a resonator for vocal communication or mating calls. Its hands had four fingers, including a distinctive thumb spike likely used for defense. The teeth resemble those of hypsilophodonts: leaf-shaped, laterally flattened, and well-suited for slicing tough vegetation—like a natural pair of scissors. Fossil evidence suggests Iguanodon orientalis lived in herds and frequented lush, wet environments such as swamps, lakeshores, and riverbanks. Its diet likely included ferns, cycads, conifers, and horsetails (Equisetum). --- Material: Resin cast Dimensions: Skull length approx. 90 cm (35.4 inches) Price: $975 Production Time: Made to order.
