Iguanidae
Iguanid lizards are usually the most commonly encountered ones. They can be either arboreal or terrestrial. Typically but not always they feed on insects and other invertebrates. Most are egg-layers, and most are very visually oriented, communicating with one another with their colors and behavioral signals. Mates are courted, territories are defended, and during confrontations they often bob their heads, do body push-ups, and open their mouths at one another

Iguanidae, Ctenosaura sp.. Most common one is Ctenosaura similis. But in Mexico there are many other different species around. You might check some of the ones mentioned in the Wiki link. My guess for yours would be Ctenosaura similis, but the picture is a little bit blurry to see all the details, so I am not sure about the species.
