On December 28th, 2017 (initially planned for November 1,
2017) Post Authority of Armenia - Haypost -
issued a set of 2 commemorative stamps, shows some prehistoric animals
- flying reptile: Pterosaurs and Tyrannosaurus dinosaur.
Even though some dinosaur's fossils found in Armenia, it was not enough
to associate it with any particular specie, due this reason "classical"
dinosaur and pterosaurus are
depicted on the stamps.
were flying reptiles 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.
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.
