Can a komodo rhino kill a tyrannosaurus?

Don't think there's such a thing as a komodo rhino. There's a komodo dragon, but it couldn't kill T Rex. Not right away, but if it bit it and ran away, maybe. Their mouth is highly septic.

No, stomach acids would kill it.\nI do not believe that whales can get it anyway.

It is possible, but unlikely. Either way, I wouldn't go kicking rattlesnakes in rubber boots.\n\nRattlesnakes are really very docile creatures. Unless you're being stupid, your chances of getting bitten are very low. They know they can't eat you, so they aren't going to specifically go out to attack you. They'll only bite if they feel it's necessary for self defense. They aren't stupid - if they waste their venom on you, they don't get any dinner. They will also warn you any time they are scared. You'll usually have plenty of time to back away from them and give them their space so they don't feel threatened.

Despite it now weighing more than a fraction of an ounce, the Harvestman spider (daddy longlegs) is one of the most deadly organisms. No, it is not able to kill many mammals, but for its size, its venom is more potent than any other venom.

The bear, not only would he have a weight, up to 1,500 lbs for a full grown Kodiak compared to about 350 for the gorilla, and height advantage and he would be more aggressive. The Kodiak has been known to kill with one blow a full grown bull, pick him up and carry for almost a mile before putting it down which pretty much slowed down the cattle business on Kodiak Island.

OK, because I'm a complete dork, there's a vaguely to scale picture of the largest dinosaurs compared to a few tanks at http://www.panix.com/~tomr/dino_vs_tank.JPG.\n\nAt first, I thought that the dino would have no chance, but looking at how big they are, maybe they do.  The biggest dino was around 100 tons, and looks big enough to just step on the tank (the WW2 tank, at least). Even with only one foot, that's 25 tons or so of extra weight.  I have no idea if that would crush the tank or not, but I'd imagine it wouldn't be too good for the suspension.\n\nThe big meat eating dino doesn't have a chance--it's only half the weight of the WWII tank, let alone the modern one, and there's no way its teeth could get through the armor.\n\nThen again, like they told me when I learned to use power tools: when it's metal vs. flesh, flesh looses.  I'm trying to imagine taking on a strong metal box 1/4 my weight....don't feel like I could do much against a fire hydrant or a parking meter.\n\nAs far as the tank's weapons...the different types of machine guns can penetrate about 2 and 3 feet into flesh (those gruesome facts came from http://www.steyrscout.org/terminal2.htm and http://www.tacticalforums.com/ubb/Forum78/HTML/000674.html), which might not really impress the big dinos. Depends on where you hit 'em, I guess.....course, the main gun on the tank is a completely different story, but I don't know if you'd be able to swing it on target if the dino was right on top of you.

No,but I have seen a monkey break a beer bottle and threaten to kill that puppy if it ever came near him again. Almost the same thing,right?

Dinosaurs were members of the SuperOrder Dinosauria. No member of Dinosauria are alive anymore.\n\nReptiles, like Komodo dragons or crocodilians are not and never were dinos- a seperate branch of the evolutionary tree.\n\nThere are kinds of fish (coelocanth, shark, etc.), plants (ferns, fungi), reptiles (crocs), insects, and other groups that are very similar to their prehistoric counterparts- but none of these were dinos either.

I would say so.  To kill one you destroy their brains, and brains operate on oxygen to sustain all metabolic processes.  From this I conclude that yes they do need oxygen.

Elasmosaurus, as a top predator probably didn't have too many enemies.\n\nWhile some of the larger mosasaurs such as Tylosaurus may have been able to give Elasmosaurus a fight, it's unlikely that they would have.  Elasmosaurus' body was quite well armoured, almost like a sea turtle's, and it would have been quite tough to injure.\n\nA really large predator like Kronosaurus could have done quite a number on Elasmosaurus, but there would probably be enough other prey about that it would prefer those to the overly crunchy plesiosaur.

If its mano-a-mano (well animal on animal), it would depend who was on their home turf, as the scorpion would freeze or the emperor penguin die from the heat!

I don't think it's really possible to know that without testing it. But I would guess that your idea is right, because there would not be enough venom to kill an animal that large. It would probably make it sick. But then again, a whale, or any other really large animal, would react differently to the venom. It might kill it despite the size.

Yes. They are only 4 feet tall and have 3 eyes. They have red skin and are hostile. They will kill you if you invade their terriorty.

The biggest dinosaur currently known is generally conceded to be Argentinosaurus, a huge sauropod (brontosaur-type) from the late Cretaceous of South America.  Extrapolation from the size of the fossilized bones found indicates that Argentinosaurus was up to 120 feet long and weighed in the neighbourhood of 100 tons.  The maximum weight estimate for a huge dinosaur like Tyrannosaurus was 8 tons, so Argentinosaurus was massive even for a dinosaur.\n\nAs to how some animals survived, while others did not is one of the big, big mysteries of the KT extinction event.  Why did pterosaurs all go extinct, but birds survive?  Why did ammonites and belemnites all go extinct, but sharks and nautilus survive?  Why did giant marine reptiles like mosasaurs and icthyosaurs go extinct, while crocodiles and snakes survived?  Some of those are hard to explain if an asteroid impact was the sole reason for the extinctions.  The general consensus seems to be that there were a large number of factors such as continental shifts creating faunal interchange between long isolated populations, which could spread disease among dinosaurs.  The continental shifts would also have altered ocean currents, changing environments and climate, and altering existing eco-systems (especially some of the rich shallow seas that existed at the time).  Adaptive radiation of flowering plants (Angiosperms) in the late Cretaceous may have caused stress on those animals that were dependent on the competing Gymnosperm plants.  Co-evolution of many insects in response to the radiation of Angiosperms may have somehow favoured the survival of the birds over the pterosaurs.  \n\nThen when the asteroid impact occurred, it was the straw that broke the camel's back for many of these species that were under intense pressure, but other species were able to survive.

Pretty much anything that is smaller or slower than a lion. This does exclude rhinos, hippos, end elephants.

It is theoritically possible to clone a dinosur from its bones, however it would have to be recent bones to still have marrow cells in the, and since no dinosaurs have died recently then no, it is not practically possible. Plus, you would have to have a surrogate mother large enough to carry a dinosaur feutus to full term.

Yes.\nI initially was going to talk about the Komodos from Indonesia, and also about crocodiles and alligators, but the best most interesting answer is here:\n\nhttp://www.fortunecity.com/skyscraper/redmond/23/dragon.html\n\nI do not copy the material as to not plagerize their material, but well worth checking out on this concept.
