tough or woody, preferring softer (but firm) vegetation. The microwear patterns also show that it used a simple up-and-down motion of the jaw, and did not use complex jaw movement to chew its food like ornithischian dinosaurs or contemporary cynodonts. This microwear has not yet been observed on the teeth of A. laaroussii, but it is unknown if this is a genuine feature relating to a difference in diet and feeding habits between the two species or if it is just a feature of preservation. The fully developed palatal teeth suggest that it was using them for feeding in a specialised manner. However, no functional studies have been performed on the palatal teeth so it is unknown exactly what they were used for, although their similar shape to the marginal teeth suggests they were used for processing similar food. A pterygoid from a younger individual of A. madagaskarensis has fewer rows of palatal teeth that are smaller in size than those of the larger, mature individuals, indicating that Azendohsaurus increased both the number and size of its palatal teeth as it grew into adulthood. Younger individuals also had fewer dentary teeth than adults, although the difference was much less extreme compared to the palatal teeth (16 compared to the 17 of mature specimens). Body posture The body posture inferred for Azendohsaurus is a mixture of sprawled and semi-sprawled. The hind limbs have been interpreted as being completely sprawled outwards from the body, with its femur held straight out and the lower leg bent 90° beneath it at the knee, like a lizard. The forelimbs and shoulder girdle, however, suggest that the front of the body was held more upright than the hind quarters, with a partly downward directed shoulder socket and a humerus more suited for being held partially erect, and was similar in shape to those of sauropodomorphs. This unusual combination suggests that Azendohsaurus stood with its front end raised up off from the ground, which combined with its long, arched neck and small head, allowed it to browse relatively high off the ground, unlike contemporary low-browsing rhynchosaurs and cynodonts. Adapting to high-browsing could possibly explain the convergence between Azendohsaurus and sauropodomorphs, acquiring similar traits of the neck, forelimbs and spine to perform in similar niches. However, the more sprawling posture of Azendohsaurus probably inhibited high-browsing like that of the fully erect sauropodomorphs. Palaeopathology Despite the multitude of specimens
