To be honest, I can't see LBT 15 being a thing at all unless there is a dino resurgence like Nanotyrannus said. But even then. If it doesn't make enough money, Universal isn't going to make it. I can see sometime in the distant future (like 10-50 years), we might get a remake of the LBT movies. After all, there were several remakes running around this last decade. Who knows? It'd be cool to see a more accurate depiction of the gang and the other prehistoric creatures. After all, I'd like to see Pterano return in one of these remakes, mainly because I can't see Pterano ever returning in the current series. It would also be pretty cool to see some darker themes, like, not mature themes per se, but material that addresses more serious matters like racism, climate change, and immigration like in the first movie.
