In Depth

       Though only known from fragmentary fossil remains,‭ ‬Patagosuchus is noted for having a diverse heterodont dentition.‭ ‬What this means is that Patagosuchus had many different kinds of teeth,‭ ‬and would have been able to adapt differing feeding strategies.‭ ‬Patagosuchus is also classed as a peirosaurid crocodylomorph,‭ ‬and these are usually small meat eaters that hunt everything from larger insects to small vertebrates like lizards,‭ ‬to scavenging carrion.‭ ‬The heterodont teeth of Patagosuchus meant that it could hunt and feed in any of the above strategies.

       Patagosuchus should not be confused with the sauropod dinosaur Patagosaurus.
