Cretaceous impact
Stato: Guinea Anno: 1993 Notizie: In 1993 the Republic of Guinea issued an airmail souvenir sheet showing several dinosaurs against the background of a volcano and an incoming cosmic impactor.

The dinosaurs pictured on the sheet include Diplodocus, Tyrannosaurus Rex, Longisquama, Plateosaurus, Allosaurus, Brontosaurus, a juvenile Albertosaurus, Coelophysis, and Parasauralophus. |
