Fossils on samps of North Korea 2013


On November 11th, 2013, Post Authority of North Korea issued a set of three fossil stamps. These stamps issued as a booklets, one booklet with perforated and another one booklet with imperforated stamps.  On top of the stamps North Korean post also issued three postal stationaries with imprinted stamps of the same design: aerogramme, envelope and postcard with imprinted stamps.

All fossils that depicted on these stamps are uncovered in North Korea,  unfortunately the names of the stamps are  not valid taxonomic names, as they do not appear to have been properly published under the Code of Zoologicl Nomenclature.
Ditomopharangia fossil on stamp of North Korea 2013  Ditomopharangia
  
 Korean caption in Ditomopharangia says "Pterosaur fossil from Dooji valley", the valley located in the
 south of the Ryanggang Province of North Korea.
This is pigeon-sized pterosaur from Anurognathidae family, suborder Rhamphorhynchiodea, from Sinuji Series- approximately 25 cm long from the tip of the snout to the end of the tail, and probably had a wingspan of more than 80 cm. . [R1]
Dumangia fossil on stamp of North Korea 2013 Dumangia

Dumangia - Fossil fish from Duman river, the river along the North Korea- China border.
Dumangia  is not valid  genus name and the image on the stamp is not good enough to allow its identification. [R2]
Hormotoma fossil on stamp of North Korea 2013 Hormotoma synonym of  Murchisoniina
Alternative spelling: Murchisonia (Hormotoma)

Hormotoma  is a gastropod (moluscs) that is generally preserved as molds, from Paleozoic era.  There are reports of fossils of this genus from North America, Russia China, and Australia - from Ordovician and Silurian-aged rocks.
This gastropod was characterized by the long spiral shell separated by deep notches with round turns. The shell mouth was grooved and the surface was smooth. The scale length was 5 to 6¼ cm.  [R3]
The fossil shown on the stamp is more of a "form" genus - that Korean Post used it for high spired, snails that have similar shapes - because they are preserved as molds - they don't necessarily preserve other ornamentation that might actually be useful for classification.
Zelkova

Fossilized leaf of a tree from Zelkova genus.
Zelkova (from Georgian 'stone pillar') is a genus of six species of deciduous trees in the elm family Ulmaceae, native to southern Europe, and southwest and eastern Asia still alive.
They vary in size from shrubs  to large trees up to 35 m  tall . The bark is smooth, dark brown. Unlike the elms, the branchlets are never corky or winged. The leaves are alternate, with serrated margins, and (unlike the related elms) a symmetrical base to the leaf blade.  [R4]
