Early primitive forms, like <i><a href="/wiki/Mesosuchus" title="Mesosuchus">Mesosuchus</a></i> and <i><a href="/wiki/Howesia" title="Howesia">Howesia</a></i>, were generally small, typically lizard-like in build, and had skulls rather similar to the early diapsid <i><a href="/wiki/Youngina" title="Youngina">Youngina</a></i>, except for the beak and a few other features. Later and more advanced genera grew to up to two meters in length. The skull in these forms were short, broad, and triangular, becoming much wider than long in the most advanced forms like <i><a href="/wiki/Hyperodapedon" title="Hyperodapedon">Hyperodapedon</a></i> (= <i><a href="/wiki/Scaphonyx" class="mw-redirect" title="Scaphonyx">Scaphonyx</a></i>), with a deep cheek region, and the <a href="/wiki/Premaxilla" title="Premaxilla">premaxilla</a> extending outwards and downwards to form the upper beak. The broad skull would have accommodated powerful jaw muscles. The lower jaw was also deep, and when the mouth was closed it clamped firmly into the <a href="/wiki/Maxilla" title="Maxilla">maxilla</a> (upper jaw), like the blade of a <a href="/wiki/Penknife" title="Penknife">penknife</a> closing into its handle. This scissors-like action would have enabled rhynchosaurs to cut up tough plant material. Rhynchosaur teeth had a unique condition known as <b>ankylothecodonty</b>, similar to the <a href="/wiki/Acrodont" title="Acrodont">acrodonty</a> of modern <a href="/wiki/Tuatara" title="Tuatara">tuataras</a> and some lizards but differing in the presence of deep roots.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>The teeth were unusual; those in the maxilla and palate were modified into broad tooth plates. The hind feet were equipped with massive claws, presumably for digging up roots and <a href="/wiki/Tuber" title="Tuber">tubers</a> by backwards scratching of the hind limbs. Similar to <a href="/wiki/Elephant" title="Elephant">elephants</a>, they had a fixed number of teeth. Those that were further back in the jaws replaced teeth that were worn out as the animal grew in size and the teeth were worn out because of a diet of very tough plants. In the end, they likely starved to death.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p><p>Like many animals of this time, they had a worldwide distribution, being found across <a href="/wiki/Pangea" class="mw-redirect" title="Pangea">Pangea</a>. These abundant animals might have died out suddenly at the end of the <a href="/wiki/Carnian" title="Carnian">Carnian</a> (Middle of the Late Triassic period), perhaps as a result of the extinction of the <i><a href="/wiki/Dicroidium" title="Dicroidium">Dicroidium</a></i> flora on which they may have fed. On the other hand, Spielmann, Lucas and Hunt (2013) described three distal ends of <a href="/wiki/Humerus" title="Humerus">humeri</a> from early-mid <a href="/wiki/Norian" title="Norian">Norian</a> <a
