My point is its real resruch in to this topc. It says your not right. tongue.gif


If you are referring to my link, then I believe you are mistaken. It suggests tyranosaurus did NOT have lips, just a Frogfish said.

"Where can it be,
This land of Eldorado?"

"Over the mountains
Of the moon,
Down the valley of the Shadow,
Ride, boldly ride!"
The shade replied,
"If you seek for Eldorado!"

You compiled research ohmy.gif Oh my, what do you have? If you are reffering to the link, it agrees with me. But like almost all research on dinosaurs, they can collapse at anytime. I could e totally wrong, or I could be right that no dinosaurs had lips.

What information do you have to back up lips?

Quote

well just because they dont need lips dosent mean they didnt have em

i mean look at us we have an appendix but it dosent seem to have a significant function

You have a good point, but I'll tell you why this is wrong.

Evolution does not give animals unnessary organs or functions. The appendix actually does something, it helps manufacture T4 cells. But the common belief is that the appendix is a evolutionary remenant from our ancestors...It will dissappear soon if the theory is right.

Eukaryotic Cells have organelles called mitochondria. It is beieved that these mitochondria were actually once prokaryote cells that lived inside eukaryote cells. Mitochondria have useless DNA different from the whole cell. The DNA doesn't serve as a function, but is a evolutionary remenant.

Since dinosaurs did not need lips (with the exception of sauropods, but I still believe prehensile tongues were better), and no ancestor of the dinosaurs had lips, they MOST LIKELY did not have lips.

That will only happen if for some reason, people with an appendix couldn't survive; which isn't the case.

Then why do we have coler in our eyes. The coler in the eye has nothing to do with seeing.

Can you tell us why that is?  tongue.gif

It is a useful means of telling different individuals apart, or at least helps in doing so. It also encourages eye contact, which helps to increase facial recognition, which in turn strengthens familial bonds. All of these traits would have been very useful to our ancestors.

That makes little sense to me, I could understand if you said that those which did not have coloured eyes were maybe considered unattractive and therefore didn't mate and produce offspring; is that what you were getting at?

Yes and no. I am saying that having colored eyes helps to build a tighter bond between family members, and that a family with tight bonds has a strong reason to work together as a team. It does not in and of itself make the creature better suited to survival but it helps to build traits which do so.

I think that attractiveness played some role in the genetic selection of colored eyes over non-colored eyes. However, it is a case of the tail wagging the dog. Those who had mates with colored eyes were the ones more likely to make eye contact, and thus more likely to have strong family bonds. They bred and were successful, while those who did not care about eye color were less likely to make eye contact and were less successful overall. The result was that more children were raised to find colored eyes attractive. It was because eye color had this effect that it became attractive, not the other way around.

Back on topic...If dinos indeed have lips, then the only plausible ones would be the sauropods. They could of possinbly used them to manipulate leaves...But the prehensile tongue like giraffes is more plausible.

Wow, what an out-there question to ask, but it's a good one. I've never really thought much on it, but I'm sure that some had to, considering what the diets of some were. Wouldn't you need lips to lap up water from a nearby stream or lake?

I'd really like to see some ideas tossed around on this one.  geek.gif

No, that's what a tongue is for. How do snakes, turtles, crocs, and birds drink water?

Pilgrim,
Obviously, I wasn't referring to beaked and duckbilled dinosaurs, that should have been a no brainer.  By "all", I was referring to all toothed dinos.

Frogfish,
For someone who claims he keep reptiles, I am rather disappointed in your inability to grasp this concept.  Komodo Dragons and other varanids must have had a very similar feeding behaviour to theopod dinos.  They even have remarkably similar, serated and flat teeth.  They swallow small prey whole and tear larger prey apart to swallowable size as would theropods.  And THEY HAVE LIPS!  Their mouths form a tight seal so when they breath, the air comes through their nostrils and their olfactory bulb picks up scents.  That's one of the reasons they have lips, the other is to prevent their mouth tissue from drying out.  Theropod dinosaurs probably also had the thick fleshy gums like monitor lizards that largely cover the teeth.

The truth is in the fossil evidence.  Toothed dinosaurs have holes in their jaws for the blood vessels that feed the lip tissues.  Crocs do not have these holes because they have no lips.

It is really not a debatable point frogfish, you are wrong again.  

DC
