I know this might shock LBT fans who saw the first movie, but how the heck woudl Bron know his wife was killed by a Sharptooth rather then the Great Earthshake? Even if another Longneck found her body, how would the Longneck know that she wasn't fatally injuried by the Great Earthshake, died of her wounds, and then a Fast Biter or something sabotaged the corpse?
On the flip side, if Bron HAD talked to Rooter, he ought to have known that Littlefoot could still be alive, though Bron doesn't appear to have known that, or else, one would have assumed that, being a good father, he would have turned down leading a herd so he could find his son?
Also, does anybody find it odd that Bron didn't act more suprised when he found that Littlefoot WAS indeed alive and more in front of him? I mean, you'd have expected him to hop up and down and cheer. Nor was the response from his in-laws what we'd have suspected.
Also, one wonders why Bron never tried to figure out THEIR fate as they could have given him news, presumably, on Littlefoot, yet he NEVER mentions that he ever bothered to look for them. Littlefoot yes, them, no.
One wonders if perhaps he left Littlefoot's mother for a kind of selfish, perhaps Pteranoish reason and maybe his in-laws were sour at him over it and so he didn't want to go find them when he heard his wife died to try and find out Littlefoot's fate.
At any event, barring Bron and/or Grandpa and Grandma Longneck lying about what happened with Bron, movies 1 and 10 seem to contradict each other.
