On December 28^th, 2017, (initially planned for November 1, 2017) Post Authority of Armenia - Haypost - issued a set of 2 commemorative stamps, showing some prehistoric animals - the flying reptile, pterosaur and the dinosaur Tyrannosaurus.
Even though some dinosaur fossils have been found in Armenia, there was not enough material to associate them with any particular species, so Haypost used the classic dinosaur and pterosaur for these stamps.

Pterosaurs were flying reptiles that existed during most of the Mesozoic: from the late Triassic to the end of the Cretaceous.

Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. Early species had long, fully toothed jaws and long tails, while later forms had a highly reduced tail, and some lacked teeth.

Many sported furry coats made up of hair-like filaments known as pycnofibers, which covered their bodies and parts of their wings. Pterosaurs spanned a wide range of adult sizes, from the very small to the largest known flying creatures of all time.

Tyrannosaurus is a genus of theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), is one of the most well-represented of the large theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 68 to 66 million years ago.
