There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

It appears that History’s mightiest terrestrial predator was not without fear, but what was eating it?

@brobear :

About #61and the linked account: very interesting theory which I'm agreee with. It's sure that even a T-rex would have an enemy, no one wild creature hasn't ennemy to fear. And the parrallel with the extant lions and tigers is good. A superpredator on land is never "invulnerable". At any one time, inevitably, he could be in a delicate situation, and of course, having need to drink at last one time a day...

An other interesting point I notice is the lenght of the whiskers according to the social or solitary way of life of the lions and tigers

Quote: Before we get into the science aspect, let’s examine how T-rex most likely drank. I believe the Cassowary is the best example we have to compare it to today. I’ve studied footage of ostriches drinking and their technique is similar, except that there is excessive head raising in order to get the water to flow down that long neck.  (If anything, an ostrich would be a good comparison for a sauropod in terms of drinking – write that down). Let’s look at this video of a Cassowary imbibing.  This is probably similar to what a large theropod did: remaining upright, possibly wading into the water a bit, lowered its head down, then lifted it back to the horizontal to ingest. Note that the bird remains alert the entire time. 
 
Of course, while doing this a Tyrannosaur, or any animal small enough to fall on the menu, was a potential target for a big, hungry crocodylomorph. And let’s not kid ourselves and say, “Oh, no crocodile, even Deinosuchus, could take down a T-rex.” Pushing 40 feet, the “dread crocodile” was as large as the largest of Tyrannosaurs, with jaws that were potentially even more powerful. And, let’s not forget, crocodiles often travel in loose “gangs”. Once a prey item is pulled off balance and into the water, it’s a feeding frenzy that no Tyrannosaurus could survive.  
  
*Brobear: I would wager on the T-rex having the stronger bite; not that it would save him.
