this is a world where only big, thick, busty, muscular dino girls lives. unlike regular know dinosaurs, those girls more durable, tough, smart, strong and intelligent. they have auto controls that they evolved not to need any male. trex girls hunts down other large dino girls, triceratops are large, strongfat women with mucular gut and big horns, and etc. and they are very well developed and seems like this world full of survival and domination
