Although once classified as a dinosaur, Azendohsaurus is now known to be an archosauromorph reptile that lived during the late Middle to early Late Triassic Period, roughly 241 to 237 million years ago. This fascinating creature represents an important link in understanding the evolution of archosaurs, the group that would eventually give rise to dinosaurs, crocodiles, and pterosaurs. Fossils have been discovered in both Morocco and Madagascar, showing this reptile had a relatively wide distribution across what was then the supercontinent Pangaea.
Azendohsaurus was a bulky, quadrupedal herbivore with some truly remarkable features. Unlike other early archosauromorphs, it had developed an unusual body plan with a relatively short tail and robust limbs. Most intriguingly, it displayed an odd mix of postures - its hind limbs remained in a sprawled position like earlier reptiles, whilst its forelimbs were held in a more upright stance, hinting at the evolutionary changes to come.
The creature's most striking feature was its long neck supporting a proportionately small head equipped with remarkably sauropod-like jaws and teeth. This convergent evolution - where unrelated animals develop similar features - shows how effective certain body plans can be for specific lifestyles. The leaf-shaped teeth and powerful jaw muscles were perfectly adapted for processing tough plant material.
The discovery of nearly complete skeletal remains from Madagascar in 2010 revolutionised our understanding of this creature, revealing it to be far more complete and unusual than the original fragmentary fossils from Morocco had suggested.
What made Azendohsaurus distinctive?
Azendohsaurus had a unique combination of sprawled hind limbs and more upright forelimbs, giving it an unusual gait. Its long neck supported a small head with remarkably sauropod-like jaws and leaf-shaped teeth, despite not being a dinosaur.
Behaviour
As a herbivore, Azendohsaurus would have spent much of its time foraging for plant material, using its powerful jaws to process tough vegetation. Its unusual limb posture suggests it may have moved differently from other reptiles of its time, possibly representing an evolutionary experiment in locomotion that preceded the fully upright stance of later archosaurs.
Azendohsaurus FAQ
What did Azendohsaurus eat?
Azendohsaurus was a herbivore that fed on various plants available during the
Triassic Period. Its leaf-shaped teeth and powerful jaw muscles were specially adapted for cutting and processing tough plant material, similar to how much later sauropod dinosaurs would feed.
How big was Azendohsaurus?
Azendohsaurus was a medium-sized reptile, reaching approximately 3 metres in length and standing about 1.5 metres tall at the hip. It weighed an estimated 200 kilograms, making it a bulky but not enormous creature by prehistoric standards.
When did Azendohsaurus live?
Azendohsaurus lived during the
Triassic Period, specifically from the late Middle Triassic to early Late Triassic, approximately 241.5 to 237 million years ago. This was well before the age of dinosaurs properly began.
Where was Azendohsaurus found?
Fossils of Azendohsaurus have been discovered in two locations: Morocco in North Africa and Madagascar off the eastern coast of Africa. The original specimens came from the Atlas Mountains of Morocco, whilst more complete remains were later found in Madagascar.
How do you pronounce Azendohsaurus?
Azendohsaurus is pronounced 'ah-ZEN-doh-SORE-us'. The name breaks down into 'Azendoh', after the Moroccan village where it was first found, and 'saurus', meaning lizard in Greek.
What does Azendohsaurus mean?
Azendohsaurus means 'Azendoh lizard'. The name honours the village of Azendoh in the Atlas Mountains of Morocco, near where the first fossil fragments were discovered by Jean-Michel Dutuit in the early 1970s.
How fast could Azendohsaurus run?
The running speed of Azendohsaurus is unknown, but its unusual mix of sprawled hind limbs and more upright forelimbs suggests it probably wasn't built for speed. Its bulky build and plant-eating lifestyle indicate it was likely a slow-moving browser rather than a fast runner.
What type of dinosaur was Azendohsaurus?
Azendohsaurus was not actually a dinosaur at all. Although originally classified as one, it's now known to be an archosauromorph reptile - a member of the broader group that includes the ancestors of dinosaurs, crocodiles, and pterosaurs, but not a dinosaur itself.
Was Azendohsaurus related to birds?
Azendohsaurus was distantly related to birds, but only in the sense that both are archosauromorphs. As birds evolved from theropod dinosaurs, and Azendohsaurus was not a dinosaur but rather a more primitive archosauromorph, they shared a common ancestor much earlier in reptilian evolution.
How many Azendohsaurus fossils have been found?
The original discovery consisted of partial jaw fragments and teeth from Morocco. However, the Madagascar species is known from numerous specimens representing almost the entire skeleton, making it one of the most completely known early archosauromorphs.
