Look at this picture, fundamental early splits in amniote evolution are documented in their temporal fenestrae - openings behind the orbit that probably function in reducing the weight of the skull and in conserving calcium. The argument is that bone is costly to produce and maintain, as well as being heavy, and it can be advantageous to dispense with it where it is not required.Much of a skull is under stress from the movements of the jaws and neck muscles, but some spots, in the cheek region and palate, are under very little stress, and openings may appear, and the skull becomes an engineering marvel of struts and braces without reducing the effectiveness of the skull. Fenestrae also provide additional attachment edges for specific jaw muscles, and they allow jaw muscles inside the skull to be out.With the curiosity of dinosaur skull, there are many dinosaur skull replicas appeared.
