There is a rare type of reptile called the alligratorian that is related to a alligator.

yes, there are a few types of vegetarian reptile such as the Chuckwalla and the uromastix, they are both vegetarian and the uro's will eat bird seed and veg and are smaller than the Chuckwallas. chuckwallas tend to eat a lot of veg lol and can be quite greedy. :)

I'm afraid that most lizards that eat fruits and vegetables have long toes. You will need to be more specific. For example, does the lizard ONLY eat fruits and vegetables, or does it eat other things, as well? Is it a desert species, or a tropical species? Is it large, or small?

A list of the more common species that eat plants includes the green iguana (and many other iguana species), uromastix (all species), blue-tongued skink, monkey-tailed skink, and bearded dragon. There are more.
