Real answer: Because ghost’s aren’t real, of course.
Hippie bullshit answer: Because ghost’s have unfinished business, and since dinosaurs weren’t sentient in the way humans are, they won’t have any unfinished business.
There’s sort of a curve to it. The older a ghost gets the more powerful they get. That’s why most ghosts you see are older. However, the longer they’re around the more likely they are to finish their business or to get over it and move on.

They probably got a lot more fibre in their diets than modern day humans do, so it wouldn’t take them as long to finish their business.
