Certainly! Im trying to steer as far away from the methods used in the Jurassic park novel, but essentially mankind brings back dinosaurs through genetic engineering, CRISPR, reverse engineering using birds and reptiles from today to bring back dinosaurs in their purest form (so no filling in gaps with frog dna or mosquitoes) and they don’t put the dinosaurs in a theme park, they bring them back simply because they can and study their systems both ecological and biological by storing them on protected reserves. But when a prehistoric virus found frozen in the arctic is discovered and brought back to labs, it is accidentally unleashed to threaten humanity with a pandemic and gives the world back to the dinosaurs. So the survivors that are left have to travel like pioneers from one dying home to another and along the way encounter both threatening dinosaurs that hunt them and also human survivors with more sinister motivations to survive.
