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 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]
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.
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]
