and by the way, what does "gaphanax" mean, i no saura, but not the last part.

Saurophaganx means "lizard-eating master"

You know venom seems to be the topic here, and were suppose to be talking about crest, seems like it was a pretty common trait among ancient reptiles. There are many species of lizard that have crest and horn-like crest, and something these modern reptiles have in common aswell is tending to have skin that changes pigment. Perhaps they work as environmental receptors.

I doubt it...Displays Frilled lizard, etc...

[speshall mareens]

such is the theory, but just one and  that brings up the debate of warm or cold bloodedness. the enviremantal thing does.

Since we didn;t live back then, the best we can guess is by looking at their closest relatives. Crests on birds and other reptiles (frilled lizards, chameleons, anoles) are used for display purposes...

[speshall mareens]

exactly, i think we kinda established that early on and then moved on to the venom thing

Alright, but look at the species of lizards you just named (also iguana's,) the chameleons, anoles, and iguanas all change skin pigment to match their environment... you really can't see a biological link there? Im not sure whether the frilled lizards do this too, but I have owned all the others and know it is a fact that they do. Im not saying they don't come into play for mating display, only that if its not linked, it is a far fetched coinscidence being that these different species live all over the globe, and have these two traits in common.

i have never heard of an iguana changing color. anole can only change to freen or brown.  a LOT of animals can fluctuate their colors simply by pumping blood to that area. this might have been done in sailed and crested dinosaurs as well. the whole color pigmment changing thing depends on irs evolutuion. this is how the venom thing started too

[CaitSith]

I had an iguana for six years as a child, they are not quite as developed in this as chameleons and anoles, just bright green to dark blackish olive green. Whats really neat is to hold one around the middle for several minutes and it will leave stripes like a tiger where your fingers were resting.
