Not sure how out of date the research is, but in the original Jurassic Park book, there are roaming packs of these things that overwhelm and kill people.
Though the on screen scene of them killing people happens in the second movie, it actually takes place in the first book IIRC… anyway, they’re basically depicted as land piranhas.
(Again, IIRC, Jurassic Park the book basically gets set in motion with a family of tourists being eviscerated by a pack of compys… but the first movie dropped this from the story, then when the second movie comes out they basically use this scene as the intro for that, but its on a different island and used to set off an entirely new story?)
