Archovember Day 26: Hyperodapedon huxleyi

Possibly the most bizarre archosauromorph I’ve had to draw so far, Hyperodapedon looks more like a giant mole-rat or at least some other type of synapsid than a relative of archosaurs. But Hyperodapedon huxleyi was a Rhynchosaur, and as most strange paleofauna does, it came from the Triassic.

Hyperodapedon is from the Late Triassic, to be specific, and fossils have been found in Africa, Eurasia, and the Americas, indicating they were common and spread all across Pangea. (H. huxleyi in particular was found in India, but could certainly have spread further.) It was a badger-sized herbivore that used its strange “beak” and stocky limbs to dig for roots and tubers. It also likely would have eaten tough plants like cycads and conifers with its powerful chewing muscles. It had an abnormally wide, triangular head.

Since they ranged across the globe, Hyperodapedons would likely have been prey for a variety of large predators, such as Herrerasaurus in South America and Poposaurus in North America.

Hyperodapedon is an extinct genus of rhynchosaur reptiles which lived throughout what is now Africa, Europe, India, and North & South America during the Carnian stage of the Late Triassic Period some 237 to 227 mya. Like other rhynchosaurs, it was a heavily built archosauromorph, distantly related to archosaurs such as crocodilians, pterosaurs, and dinosaurs. The first remains of hyperodapedon consisting of a partial skeleton where discovered in the the Lossiemouth Sandstone near Elgin, Scotland by Reverend Doctor Gordon who gifted said specimen to Thomas Henry Huxley. Huxley first named the animal at a Geological Society of London conference in 1858, then formally describing the animal in 1859; dubbing the animal Hyperodapedon meaning above pavement in greek, with the specific name gordoni honoring Rev. Dr. Gordon. Since then hundreds of hyperodapedon specimens have been recovered across several continents making it one of the best studied and well-understood rhynchosaurs and creatures of the Triassic in general. Today at least 5 species are considered valid: H. gordoni, H. huxleyi, H. sanjuanensis, H. huenei, & H. tikiensis. Reaching around 4.3ft (1.3m) and 20lbs (9kgs) in weight, Hyperodapedon was a stocky animal with thick limbs and a broad body. There wide, heavily built skulls sported a distinctive blade like beak and several rows of teeth on each side of the upper jaw, and a single row on each side of the lower jaw, creating a powerful chopping action when it ate. In life hyperodapedon where proficient burrowers, utilizing there unique beaks and strong limbs to tunnel into the ground. These herbivorous animals also used there beaks to break apart and feed on dense, tough vegetation most notably seed ferns.
