Remaining creatures in the park break out. All creatures that escaped from Prehistoric Park are prehistoric creatures including Tyrannosaurus Rex, Triceratops, Elasmotheriums, Parasaurolophus, Mammoths, Ornithomimus, Microraptors, Incisivosaurus, Titanosaurs, Stegosaurus, Toxodons, Terror Birds, Smilodons, Nyctosaurus, and Deinosuchus, and modern animals such as elephants, rhinos, gorillas, giraffes, Nile crocodiles, hippos, lions, tigers and cheetahs. But will they survive without us, will they really have second chance, and is extinction forever?

All escaped creatures from Prehistoric Park have survived. They can survive without humans because they either lived before humans evolved or they quickly adapted to their new surroundings. There are now prehistoric species and nonnatives in future North America, with Mammoths, Elephants, Rhinos, Hippos, Lions, Tigers, Gorillas, Giraffes, Cheetahs, Elasmotheriums, Toxodons, Smilodons, Terror Birds, Troodons, Saurophaganax, Triceratops, Ornithomimus, Parasaurolophus, Tyrannosaurus Rex, Stegosaurus, Dryosaurus, Brachiosaurus, Microraptors, Incisivosaurus, and Titanosaurs living in and near the Great Plains alongside deer, bison, cougars, wolves, bears, pronghorns, and other native Great Plains species, and with Nile Crocodiles, Elephants, Rhinos, Hippos, Gorillas, Lions, Tigers, Giraffes, Deinosuchus, Parasaurolophus, Tyrannosaurus Rex, Triceratops, Nyctosaurus, Ornithomimus, Toxodons, Terror Birds, and Troodons living in southeastern United States' swamps. So extinction isn't forever and they finally got their second chance.
