No, I may not have heard of them. I had some doubts about GSP's suggestions but what do K&R have to say?Anyway, as regards T.rex and it's capabilities, are you familiar with the work of Krauss and Robinson as regards possible hunting techniques against triceratops?
Interesting but I don't buy it. IMO a T.rex would just bite the flank or belly of Triceratops without bothering to push it over. One bite could probably cause catastrophic bleeding, or (according to one old study) cause the internal organs to fall out.What they propose, and Robinson is now deceased btw, is that T.rex engaged in the practice of "cow tipping". They saw that modern animals such as cows, horses, bison and rhinos rest with their limbs tucked underneath their bodies, so to get upright they essentially just have to stretch their legs. If they end up on their sides for whatever reason, for instance the notorious practice of cow tipping, or just rolling on the ground, as we see horses do at times, they struggle to get upright. They timed various animals and found it took between 3 and 10 seconds to get upright. Then, and doing a lot of complicated calculations with the presumed body mass for a full grown Triceratops and a full grown T.rex, combined with the speed with which T.rex could charge into the flank of Triceratops without injuring itself, they concluded that T.rex may have hunted Triceratops, and other large prey animals, by ambushing them from the flank and using their body mass, speed, arms and heads, to tip the animal over. Then when it was on the ground and struggling to get up, deliver heavy bites into it's ribs combined with heavy rakes from it's feet.
They propose that it's large head, type of teeth and it's larger than usual feet make this killing strategy possible. They also propose that the purpose of it's arms, small as they were, was to latch on to the upper side of the prey and assist in pushing it over. They do of course go into some detail to explain all this. They do not state that this is the only hunting strategy used by T.rex, or enter into the debate about potential pack hunting, only that this "cow tipping" is a physical possibility. Perhaps this hypothesis has gone cold due to the demise of John Robinson, but it's certainly an interesting proposal.
I cannot find a link to their work and am going by a hard copy.
