It is currently unknown as to whether or not there will be a Season 2 of Jurassic Fight Club. At first, there were talks of producing one. However, it was then postponed, until further notice, for unknown reasons. In a recent interview, Dinosaur George stated that the History Channel would think of the possibility, but, until then, the project is cancelled, due mainly to the CGI in the show being way too expensive. In that same interview, George Blasing also revealed some ideas that he had for the proposed 2nd installment in the series, if it ever gets made. Among them was an enormous series finale, with Tyrannosaurus Rex, Spinosaurus, Giganotosaurus, and Carcharodontosaurus all fighting with each other, despite the fact that they did not ever live in the same time, or in the same place, together, and that there is no fossil evidence of such a fight.
And, so, the conclusion about Season 2 of Jurassic Fight Club is that it is very uncertain, currently, as to what its future holds, for it. As of now, it appears that it will be very unlikely to be made in recent years. However, the History Channel might possibly produce it, if they manage to get more funding.
