The new Royal Mail First Day
Cover dedicates its new collection to the Dinosaurs. Dinosaurs were a hugely
successful group, dominating the land worldwide for more than 60 million years
and ranging in size from less than a metre long to 50-tonne monsters. During
this period, ichthyosaurus and plesiosaurus were the top marine predators,
while flying reptiles, the pterosaurs, ruled the skies. The collection gives
information on 10 dinosaurs. It is a first introduction to these prehistoric
lizards.
