The River Lizards, as they have come to be known, are a suggested genus of small theropod dinosaur.Their exact classification is not known (as they are cryptids), although a variety of primitive ornithomimosaur similar to Pelecanimimus or Harpymimus is the most widely accepted theory. Other suggestions have been made that they are perhaps descended from a member of the Troodontidae, or Dromaeosauridae families.
Max Height: 3.5 ft (1 metre) [to five feet] Both of these models can easily be combined into a description of one kind of "Minidinosaur" and the size given for the "River Liz" matches the"Mountain Boomer" male. In fact there is no reason to make the size differences into sex differences rather than growth stages. The "River Liz" head should similarly be shortened and roundish, and the coloration of both being in basically a green background shading to gray in parts like the belly, overlain by large irregular brown bands or splotches. The back has a sort of a crest on it and there may be hornlike structures on the head. All of this is in agreement with the actual reports.
Max Length: 5 ft (1.5 metres)[to 2 meters/ 7 feet long]
Max Weight: 33 lb (15 kg)
