Although once classified as a dinosaur, Dimorphodon is now known to be a pterosaur - a flying reptile that soared through the skies of Early Jurassic Europe around 200 million years ago. This medium-sized pterosaur was named by the famous palaeontologist Richard Owen in 1859, making it one of the first pterosaurs to be scientifically described.
Dimorphodon was a distinctive pterosaur with a wingspan of approximately 1.4 metres and a body length of similar size. Its most remarkable feature was its large, deep skull which housed two different types of teeth - a rare characteristic among reptiles that gave this pterosaur its name meaning 'two-form tooth'. The front of its jaws contained large, pointed teeth perfect for grasping prey, whilst the back teeth were much smaller and more numerous.
As a carnivorous pterosaur, Dimorphodon likely hunted small vertebrates such as fish, lizards, and early mammals, though it would also have consumed insects and other small invertebrates. Its powerful jaws and varied dentition made it well-adapted for catching and processing different types of prey. Recent research suggests it was more of a generalised predator rather than specialising in either fish or insects alone.
Dimorphodon possessed the typical pterosaur wing structure, with a membrane of skin stretched between an elongated fourth finger and its body. However, it was likely not as strong a flier as later pterosaurs, possibly spending considerable time on the ground or clinging to cliff faces along the coastal environments where its fossils have been discovered.
What made Dimorphodon distinctive?
Dimorphodon had an unusually large, deep skull relative to its body size, housing two distinct types of teeth - large pointed teeth at the front and smaller teeth at the back. Its wingspan reached about 1.4 metres, and it possessed the characteristic pterosaur wing membrane supported by an elongated fourth finger.
Behaviour
Dimorphodon likely spent time both flying and walking on the ground, using its wings for gliding between perches on coastal cliffs. It was probably an opportunistic hunter, catching small vertebrates and invertebrates both in flight and whilst perched, using its varied teeth to process different types of prey.
Dimorphodon in Popular Culture
Dimorphodon has appeared in several documentaries about prehistoric life and occasionally features in dinosaur-themed media, though it is less commonly represented than larger pterosaurs like Pteranodon.
Discovery
Dimorphodon was first described by Richard Owen in 1859. The original fossils were discovered at Lyme Regis, Dorset, England.
Dimorphodon FAQ
What did Dimorphodon eat?
Dimorphodon was a carnivore that hunted small vertebrates such as fish, lizards, and early mammals. It would also have eaten insects and other small invertebrates. Its two different types of teeth - large pointed ones at the front and smaller ones at the back - helped it catch and process various types of prey.
How big was Dimorphodon?
Dimorphodon had a wingspan and body length of approximately 1.4 metres, with a height of about 60 centimetres when standing. It weighed roughly 2 kilograms, making it a medium-sized pterosaur - much smaller than giants like Quetzalcoatlus but larger than tiny pterosaurs like Nemicolopterus.
When did Dimorphodon live?
Dimorphodon lived during the
Early Jurassic period, approximately 201 to 193 million years ago. This was a time when dinosaurs were becoming more diverse and the supercontinent Pangaea was beginning to break apart.
Where was Dimorphodon found?
Dimorphodon fossils have been discovered in England, particularly along the Jurassic Coast of Dorset. The first specimens were found near Lyme Regis, the same area famous for Mary Anning's fossil discoveries. Some specimens have also been found in other parts of Europe.
How do you pronounce Dimorphodon?
Dimorphodon is pronounced 'die-MORE-foh-don'. The name breaks down as 'di' (two), 'morph' (form or shape), and 'odon' (tooth), referring to its two different types of teeth.
What does Dimorphodon mean?
Dimorphodon means 'two-form tooth' in Greek. This name refers to the unusual characteristic of having two distinctly different types of teeth in its jaws - large pointed teeth at the front for grasping prey and smaller teeth at the back, which is rare among reptiles.
How fast could Dimorphodon run?
The running speed of Dimorphodon is not well understood from the fossil evidence. As a pterosaur, it was adapted primarily for flight rather than ground locomotion, though it could walk on all fours when not flying. Its flight speed would have been more important for its survival.
What type of dinosaur was Dimorphodon?
Dimorphodon was not actually a dinosaur at all - it was a pterosaur, a type of flying reptile that lived alongside dinosaurs but belonged to a different group. Pterosaurs were archosaurs like dinosaurs and crocodiles, but they evolved flight independently from birds and bats.
Was Dimorphodon related to birds?
Dimorphodon was not directly related to birds. Birds evolved from theropod dinosaurs, whilst Dimorphodon was a pterosaur that developed flight independently. However, both pterosaurs and birds (dinosaurs) were archosaurs, so they shared a common ancestor further back in evolutionary history.
How many Dimorphodon fossils have been found?
Several Dimorphodon specimens have been discovered since the first finds in the 1820s, though complete skeletons are relatively rare. Most fossils come from the Jurassic Coast of England, with the quality varying from fragmentary remains to more complete specimens that have helped scientists understand its anatomy and lifestyle.
