The climate on the planet began to change, and huge dinosaurs needed a lot of food, which was not enough. On this basis, natural selection began, and forced selection joined it in the form of fights between groups of animals in Dinosaurs Merge and Fight. You will become the head of one of the groups and try to survive, repelling enemy attacks with ever-increasing strength. In order to resist them, we need to develop ourselves. You can combine two identical individuals on the field to get a larger and correspondingly stronger dinosaur that will cope with three weaker ones in Dinosaurs Merge and Fight on the battlefield.
