I think the location of a dinosaur's jugular and carotid was the same as a human's. Perhaps one or both of them ended up severed. As for the bite to her back, keep in mind Sharptooth's jaws were massive. Therefore, the bite must've been very malicious. Not only was she bitten near or on the spine, but some of her peripheral nervous system neurons may have been severed, perhaps leaving her somewhat paralyzed. She had a good chunk of meat ripped right out of her. It definitely looked like something other than flesh. My theory is that she bled to death
. Yeah, even a bite like that would cause massive blood loss. They did not even have surgeons, so her blood loss, along with her possibly being somewhat paralyzed on the side she was bitten, would've caused her inevitable death. As far as her fall is concerned, her species weighed thirty-five to forty tons. Imagine weighing that much and crashing down on solid, jagged rock. She probably had many broken bones and lacerated vital organs, causing internal bleeding. When the math is done, one could conclude that she died a slow and painful death
. At least she got to see her only child one last time. She is, in my eyes, a hero for having given her life so TWO would be saved. The fact that, despite the fact that racism existed among the dinosaurs, she saved Cera was a noble move on her part. I'm certain that, somewhere in his heart, Mr. Threehorn is grateful to Littlefoot's mother for having saved his daughter. I wish she had not died, for she was a very sweet and loving mother. I'm glad her death was not in vain, though. That's just my theory as to what her cause of death most likely was.
