The fantasy version of the Dharma Initiative (OK, the medieval fantasy version) brought them there. Problem solved.I mean either way, the issue with T rexes on the Isle of Dread is that Tyrannosaurus lived in either the subtropical flood-plain that was Hell Creek, or the semi-arid plains at their southern reaches.
Meanwhile the Isle of Dread is mostly jungle which is just, not Tyrannosaurus rex territory at all.
(In this case, they could be guard dogs for the kopru.)
