Idea's or Questions About Dino's

[Mirabilis]

So I've developed new questions regarding the old dino's and their lost traits. Here's a question: Do you think dino's could regenerate lost limbs like lizards do today? =)

Amphibians, or rather salamanders (in other words, not frogs) can regenerate lost limbs, but reptiles cannot.

OH wow!

I thought lizards could regenerate too! Like geko's or Iguana's. Like "The Lizard" from spider-man studying those traits to find regeration cells and dna strands etc.

I think it's interesting to watch the intro to the hulk movie.

he shows cell regeneration using things like star fish.

I think.

lizards can lose their tail i think.

and i think it can regrow.

nut legs is a bit too much. even for a salamander?

I know that something to do with those axalotl will be made up of stem cells or something. so those things can apparently heal from amazing injury?

and they are like a species of salamander.

 Yeah I thought for sure that they could regenerate tails, that was how they escaped predators, by komodo dragons can't do that I believe correct? I guess that would apply to bigger dino's as well. But what about their tongues and such, how would scientist know that they were flat like a crocs and not forked like a snake or komodos and other large reptiles? Take a deinonychus for example, one of the greatest hunters. It would track it's prey, ambush them, pack hunter, amazing eye sight, hearing and sense of smell. I don't think it'd be far fetched to believe it had a forked tongue to help it track it's prey down.

two things.

firstly, if they find a fossil with an imprint of soft tissues, they can confirm the structure of that soft tissue.

secondly, if no soft tissue is present, they need to extrapolate using known factors.

deininychus was raptor style dinosaur and as such was very similar to today's birds. there are no known birds who have anything like a forked tongue so the reasonable expectation is that deinonychus did not.

it's not set in stone however... he he.
