Ever Smell T-Rex's Breath? 151

Posted by simoniker from the sniff-sniff-boom dept.
Jim Hawkins writes "Well, in case you never have the chance of getting up close and personal with a T.Rex, Dale Air, a company who 'nose' its smells, has recreated Tyrannosaurus Rex's breath for London's Natural History Museum. Seems people made a stink about the rotting flesh smell that would exist on T-Rex's breath - guess someone forgot to tell him to brush his teeth."

    I'm sure this has been there for several years - in fact I saw it when I was in London and I've since emigrated! I heard that the smell they recreated was actually a lot tamer than the original would have done, since obviously they didn't want people keeling over or being sick - so the smell they have there is more like vaguely rotting cabbage than the stench of rancid meat. Certainly when I saw it it didn't smell all that bad.

    I recently saw a very interesting program on Discovery that hinted at T-Rex actually being a scavenger, not a hunter.

    They had several interesting theories to back this up. For example, T-Rex had a very bad center of gravity for one thing. This coupled with the fact that it's arms were so small meant that it would not pick itself back up if it fell. This meant that T-Rex probably didn't run because it didn't want to fall. It probably walked everywhere and in walking, the only food it would be able to catch would be already dead food.

    Other reasons that pointed out it's "scavengaristic" diet where things like it's olfactory senses. Porportionally it is the same size as a vulture.

    So, the theory that it ate already rotting flesh would greatly contribute to it's problems with halitosis!
    • I agree I have seen another documentory stating the same thing, maybe the same one. But then I am sure if a T-Rex could get it in its mouth it was going to eat it. Dead or alive or an unfortunate rock with blood on it.

      It is amazing that a species that can't pick itself up from a fall could survive past a single generation. But, I'm sure there are other species with this fault. It just sounds like a bad trait to have.

      • True, but then again look at a turtle or a tortise. They have a lot of trouble if they end up on their back. They are not likely to get that way (at least unless there is some little kid nearby to place them like that) but one could attempt to go down to a stream along too great a slope and fall.

        It is not likely, but maybe the T-Rex was not likely to fall. It might still run and take that chance, but eventually poor runners would get selected out of the population too.
    • I've read that theory too, and it's a bloody stupid idea on several counts.

      For starters it would mean that there were _no_ predators over a certain size. (They all look like they're made to walk, rather than run.) Now in and by itself, that would be unusual, but not necessarily impossible. There aren't any predators the size of an elephant nowadays.

      What it wouldn't exmplain though, is why did several of the herbivore evolve defenses. Why did the triceratops, for example, need those horns and a massive bon
      • You don't necessarily need to run to be a predator. You just need to move (in whatever way) faster than your prey.

        You also don't need to be faster than a predator to avoid becoming its next meal, which reminds me of a joke about two people being chased by a bear: "The trick isn't being able to outrun the bear; the trick is being able to outrun the other guy!"

      • You ask:

        What it wouldn't explain though, is why did several of the herbivore evolve defences. Why did the triceratops, for example, need those horns and a massive bone shield, if not for defence? Why did other species grow basically armour plates? What was the evolutionary advantage of that, in the absence of predators?

        I'm not a behavioural paleobiologist, but the absence of predators doesn't seem to mean that there's the absence of reasons to fight. Maybe randy triceratops would fight over territory or a

        • Not being a girl of any species, I can only speculate.

          But from what I hear the behavioural biologists say, the reasons why the girls like the guys they do, links back to ability the guys have to survive and provide for, at least until the young are out of the way.

        • Seeing these point, I wonder about its size. Why is it so large? If it is a scavenger, what advantage would size give it? As a predator I can more easily see the benfit of size.

          Also, don't many animals with tails use them to counter balance themselves when running? From skeletons we'd know the length of a T-Rex's tail, but the weight of the tail would be primarily in the muscle mass. Maybe they had thick tails and didn't fall over as easily.
      • And you don't even have to be faster than your prey. Humans did well as cursorial hunters because they can outlast their prey. Of course humans (and other cursorials) have excellent mechanisms for getting rid of waste heat--we sweat, wolves pant. And a T-Rex, with its body mass, must have had a huge heat disposal problem. My nose itches just thinking about a sweaty T-Rex, euugh! :)
      • There were other predators in the LONG history of the dinosaurs. Velociraptors being the more famous. So the other preds would bring down the kill and the T-rex would show up and drive the preds away and eat the dead flesh. Sounds reasonable to me!

        • It's worth remembering that lions do hunt, as well as just scavenge. Likewise I'm relatively sure that T. Rex did both.

          So perhaps what's being argued about is:
          1) how long could the meat have been dead and still be appetizing, and
          2) how much of the time did it hunt, as opposed to scavenging.
          N.B.: Scavenging would be an opportunistic activity, while hunting could be planned. So perhaps the question should be how much of the time was it intending to hunt? (Or did it even adopt different techniques when se
      • It's actually quite simple. T-Rex wasn't the only large predatory therapod, and its kin have noticeably stronger teeth and forelimbs.

        I will contest that it couldn't pick itself back up, though. One of the books I had as a child showed how its musculature could allow it to rise from the ground using its hind legs. Evolution doesn't favor such big gaps in survivability.

    Revolting is beleivable, but accurate? Do we really know enough about T-Rex's to say that the synthetic breath that was created was accurate? What bacteria lived in the mouth? Did the saliva have antibodies to protect open wounds around the mouth from bacteria and infection? What was the pH of the saliva? These all affect breath . . .

      Assuming that crocodiles and dragon lizards (and probably vultures) have similar bad breath, T-Rex would almost certainly be also quite similar. The major ingredients would have to be chemicals given off by decomposing animal tissue. What T-Rex ate would matter more than anything else. The human nose is quite sensitive to (unacustomed) decomposition byproducts, enough so that Japanese find most westerners to have a very offensive body odor (from rotting hamburgers).
    • I don't know how 'revolting' the smell would be. Our sense of smell is linked in part to the threat level associated with the smell. Decomposing lizard is not great, fish is bad, decomposing cow is worse, but the worst is decomposing human.

      And that's because we 'recognize' that the decomposing human presents the greatest threat in terms of exposure to infection.
