Enter the Dragon

In the Squawk role-playing game, "dragon" is a common name for four-legged predators. Because the big predators in Squawk are archosaurs, most dragons have a classic "reptilian" shape like the crocodile above, and many of them are equally at home in the water or on land.
I like to call this critter the "catoplebas". The forelegs are probably much too long compared to the back legs. Most archosaurs have longer hind legs and higher hips than shoulders. (Obvious exceptions would include high-shouldered sauropods like Brachiosaurus, and some birds.)

Strange as it may seem, crocodiles are more closely related to birds than to lizards. Birds are dinosaurs, and some dinosaurs have toothy snouts, long tails, and scaly armor like crocodiles, but it's still hard to see the bird-crocodile connection because (modern) crocodiles are specialized for living in water (a bit like archosaurian otters.)

It's easier to see the kinship between crocodiles and dinosaurs (including birds) when we look at the different ways that crocodiles move. Like lizards, crocodiles can crawl on their bellies, but when crocodiles need to walk a long distance, lift their bodies off the ground or move quickly, they can use the "high walk" and "gallop", which are very different from the ways lizards walk and run.
