        They'll send around their lawyers, indistinguisable from T. Rex, which will rip your head off.

        Really wondering if this was the case or the bite marks were the result of battle. Once you, as T. Rex, got around those horns and had a good grip, would you risk letting go? Seems more to me like T. Rex would have bull-dogged a Triceratops, attempt to break its neck or get it in a position of asphyxiation, unable to breath through a twisted windpipe.

      Most predators I've seen go for the soft tissues, first. Liver, stomach, intestines, etc., muscle tissue usually eaten after it has "seasoned" a few days.

      As they are looking at fossils I'm wondering how they are determining the order in which feeding took place. Perhaps T. Rex hung around such a large kill for days, feeding until it was sated or felt like getting something fresh.

    "Once a Tyrannosaurus took down a Triceratops, how did it go about eating it?"

    I thought T-Rex was downgraded from a hunter/killer to a carcass plundering carrion eater, like a buzzard. Besides, didn't these Triceratopses have soft underbellies and such? Seems to me that the neck and face bits would be the LAST to go, not the first.

    • The soft underbellies were mostly organs and guts -- nutritious but not meaty. The meatiest parts of the triceratops were the huge neck muscles.

      It's not clear whether the T-Rex killed the triceratops himself, or found and ate already dead carcasses. But either way, the scientists have concluded from bite marks that this is how the feasting went.

      • I've always seen predators and scavengers start on the organy undersides. That's where most of the fats are, and also the parts that will rot the quickest. Seems like dinosaurs would need similar nutrition requirements to todays buzzards?

      Yeah, heard of that too. Something about their body structure being inappropriate for actual fighting. Their wee upper limbs, in particular.

      • Ah, but if the jaws are big enough then it doesn't need the arms (and there's some evidence that the jaws were powerful and teeth strong enough to be used for killing large prey). And one theory for why the arms are so small is to allow for such big jaws while staying balanced.

        Of course a predator as big as T-Rex would have still eaten carrion -- or just stole fresh kills from other, smaller predators since that's one of the advantages of being big. Like their modern cousins, the eagles.

      This has been debated by experts for over a century now. It's hard to get solid evidence about habits. The teeth of the T-Rex were strong enough to wrestle down live prey (to judge from bite strength, whihc can be determined from bite marks). Its seems likely it could run faster than its prey (to judge form biomechanics, but that doesn't speak to metabolism). T-rex certainly seems able to be a predator, whatever you want to read into that.

      I thought T-Rex was downgraded from a hunter/killer to a carcass plundering carrion eater, like a buzzard.

      There's still debate on this subject, but IMHO there's really too much evidence to the contrary to believe that T.Rex was a scavenger specialist (although pretty much all predators will eat carrion when available). The most interesting evidence are fossil bones of T.Rex prey that have partially-healed tooth marks that could only have been made by T.Rex. This is evidence of an animal that survived a T.Rex attack long enough for bone to partially heal (months/years). That would be hard if T.Rex were only a carrion specialist.

      There was always a lot of skepticism of the scavenger hypothesis. Just looking at T.Rex would tend to create skepticism. T.Rex is big, muscular, has incredibly strong jaws, lots and lots of sharp piercing teeth... definitely was the scariest thing around at the time. The biggest, scariest meat eater in any ecosystem is rarely a scavenger specialist.

      Another problem with the scavenger specialization idea is that T.Rex would have had pretty good binocular vision. Very useful for a predator. Scavengers don't need it so much.

      We still don't have good evidence about T.Rex's hunting style, though. I think one of the reasons the scavenger specialist idea has been so intriguing is that people had a hard time figuring out how T.Rex could take down something like Triceratops, given it's pretty tough defenses. Also, there is some evidence that T.Rex would not have been a fast runner, so how did it chase down some of the prey that seems like it would have been fast runners?

      When they find the partially-healed T.Rex bite marks I mentioned above, however, they tend to be on the prey's back. This would be pretty standard for a failed take-down, even among today's predators. Was it in fact a fast runner catching up from behind? If so, how did it take down Triceratops, which would probably turn and defend itself. Perhaps T.Rex was an ambush hunter, like today's Komodo Dragons, coming out of large brush and attacking from the side. Maybe T.Rex was a social hunter and surrounded its prey. I like to imagine T.Rex could leap over Triceratops horns, get behind it, get a grip on it's back, and shake it to death... But I have NO evidence for that, it's just fun to imagine.

        How does one go about confirming that a specific mark on the vertebrae of an animal definitely came about because a T-Rex bit it? Couldn't it have been caused by a tree trunk falling on the animal or be caused by another animal other than a T-Rex? Even herbivorous animals fight with each other and can cause serious damage to each other.

        • How does one go about confirming that a specific mark on the vertebrae of an animal definitely came about because a T-Rex bit it?

          Cross sectional shape of the mark. Spacing and placement relative to other marks. etc. A falling tree isn't going to hit the animal and put a series of triangular puncture marks on opposite sides of the vertebrae, for example.

        • Trees are unlikely to leave grooves in bone that would be mistaken for T.Rex teeth marks. In fact, being hit with a tree tends to break bones, not scrape long puncture marks. We're talking about vertebra with 3-5 inch long grooves, which are pretty much perfect matches for the shape and spacing of T.Rex teeth. In the case of intra-species fighting, these herbivores simply don't have teeth or horns which could match such grooves.

          I guess it's possible there was another big predator out there at the time, b

    • That's Horner's BS theory. There is no part of a T-Rex to hint at it being a scavenger. His claim is that an excellent sense of smell means scavenger. Most scavengers are small not oversized. His turkey vulture example is a poor one. Their size means they can cover more territory to find food. T-Rexs weren't built as long distant runners, they were built to fight by anyone's standards. They were likely short distance sprinters as in ambush hunters. You don't ambush stalk carrion. If they attacked Triceratop

      • What's funny about the turkey vulture comparison is that of (new world, at least) vultures, they're the only ones with a good sense of smell. I think it's a lot easier to find (non-avian) predators with excellent senses of smell.

        The point about soaring explaining the size of vultures is a good one, though size can still be use. Condors can more easily eat large and thick-hided carrion than the smaller vultures, and this could apply to t-rex. Also just like its size could scare off scavengers, it could al

    • One tactic T-rex might have used is the same as the giant lizard (komodo dragon), it rushes the prey, takes one septic bite, then trails the enemy till it dies.

      The hyena was considered a carrior eater but makes more kills then the lion who was considered a predator.

      And considering build, the Hyena seems closer to the T-rex then a buzzard. Powerful jaw and neck muscles that can deliver a massive traumatic bite to anything living or dead.

    • Besides, didn't these Triceratopses have soft underbellies and such? Seems to me that the neck and face bits would be the LAST to go, not the first.

      I kind of agree with you here. It looks to me like all they showed was what the T.Rex does when it's time to go after the head/neck region. It does not necessarily show that it ate those parts first. However, I haven't seen the detailed study. It is possible that there is evidence that the head was first to be consumed. Maybe T.Rex sometimes abandoned the prey after eating the head/neck region. In such cases, T.Rex marks would only show up on the head/neck, while other scavengers' teeth would show up

      • Or maybe there's other reason to believe they'd go for the head first. Maybe there's a lot of fat on the neck. Many large predators go for fat deposits first (calories), then organs (calories and micro-nutrients), then muscle (less-caloric macro-nutrients like protein).

        The only reason I can see for ripping the head off first is that maybe the body was needed intact to act as an anchor or a counterweight. Otherwise it would be far, far simpler to consume the organs and body muscles first, then concentrate on the harder to reach bits. Or maybe it was the second T-Rex that ripped the head off after the first one had gorged itself on steaks and kidneys.
