You're right about Tria's history being unknown. If I recall correctly, Mr. Threehorn tells Cera in LBT XI that Tria "has nobody." If this is the case, she has no family and most likely wandered by herself. In regards to threehorns, I read somewhere a while back that there is growing evidence they lived as single families, not herds :huh:. This means that, if Tria was all by herself, she would've had to know how to get away from sharpteeth without risking defeat by standing up to a pack of them by herself. That would be stupid and suicidal

. It is also mentioned by Noname about her becoming a mother in the next film. Nobody knows exactly how long of a time period took place in between the storylines except for Universal itself. The ending of XI, with the treesweets having grown back, may imply that at least one cold time passed, which means that perhaps these two "dated" for at least a year. This would be ample time for dinosaurs to, well, ya know what I mean

:. Lastly, in the case of her being less weak than Mr. Threehorn, it is natural for females to be weaker than males. However, building one's own strength can turn the tables. Mr. Threehorn seems to have been raised to be a fighter, and therefore is physically built for it. Tria, meanwhile, was most likely sheltered in her childhood. If she ever does kick the crap out of a sharptooth, it would most likely be due to her maternal instinct kicking in. Aside from that, she does seem rather uncertain about her fighting abilities. Even though she, like myself, may be able to fight off an assailant, there is that fear or uncertainty of one's fighting abilities. One of the most important lessons I learned in martial arts is to never fight unless one is sure they can win, and to never get overconfident. Tria is more likely using her common sense when it comes to fighting. Mr. Threehorn, on the other hand, does not seem to live up to that lesson

:. Then again, he is needed to help defend the valley against invaders. Well, I'd better end this post before I "talk" everyone's ears off

. In any case, I do love Tria's personality, and she is a good sort to have around(especially for Cera, who will need a female mentor soon

).
