Dinosaur stamps of Japan 2022

On June 16th 2022, Post Authority of Japan issued a Mini-Sheet with 10 self-adhesive stamps "50th anniversary of the establishment of Japan - Mongolia diplomatic relations".
The Mini-Sheet contain stamps of slightly different sizes with motifs of the scenery, culture, and creatures that symbolize Mongolia.
  1. Altai Tavan Bogd National Park, is a national park in Bayan-Ölgii Province of western Mongolia.
    The park includes the Mongolian side of the Tavan Bogd massif, which is divided by the triple border with Russia and China in the Altai Mountains. It is the highest mountain in the country.
  2. Eagle Hunter The westernmost province of Bayan-Ulgii in Mongolia is inhabited by Turkic Kazakhs. Eagle Hunt is a part of Kazakh culture that trains and hunts golden eagles.
  3. Reindeer grazing. An ethnic minorities called "Tsaatan", live in the Taiga region near Lake Khuvsgul in Mongolia, who breed reindeers.
  4. Eurasian wolf
  5. Scabiosa the national flower of Mongolia.
  6. Ger, Mongolian Traditional Dwelling. The carcas is made of wood and the cover is made of felt.
  7. Amur Ito (Taimen), salmonid fish. It resembles "Ito", which is famous as a "phantom fish" in Japan, and is one of the largest fish inhabiting rivers in Mongolia.
  8. Grazing scenery In Mongolia, nomadic farming (a lifestyle of grazing livestock while moving according to the season) has been practiced. Mongolia Nomads graze and care for livestock every day as shown in this picture, and sheep are bred all over Mongolia.
  9. Bactrian camel and Gobi desert. Bactrian camel (Camelus bactrianus), also known as the Mongolian camel or domestic Bactrian camel. In particular, a population of wild Bactrian camel has been discovered to live within a part of the Gashun Gobi region of the Gobi Desert. The Gobi Desert is a large desert or brushland region in East Asia. The Gobi Desert is very famous by dinosaur discoveries.
  10. Dinosaur Saurolophus and its footprints.
  11. Selvage: Sauropod dinosaur and its footprints. It depicts the world's largest ichnofossil (trace fossils) found in Mongolia and the sauropod dinosaurs that are believed to have made those footprints.

    Saurolophus is a genus of large hadrosaurid dinosaur from the Late Cretaceous period of Asia and North America, that lived about 70 million to 68 million years ago.
    It is one of the few genera of dinosaurs known from multiple continents. Saurolophus is distinguished by a spike-like crest which projects up and back from the skull. The most unusual feature for a hadrosaurine is the long, protruding, solid crest that extends upwards diagonally from the back of the skull roof. The crest, most likely, use in sexual identification. Unlike lambeosaurines, the crests are made up completely of the nasal bone.
    It was a herbivorous dinosaur which could move about either bipedally or quadrupedally. Its teeth were continually replacing and packed into dental batteries that contained hundreds of teeth.

    The first species, Saurolophus osborni, was described by American paleotologist, Barnum Brown in 1912 from Canadian fossils. The estimated length of the adult dinosaur was about 8 meters long, including 1 meter long skull and has estimated weight of around 3 tonnes.
    The fossil is on display in the American Museum of Natural History

    The second species, Saurolophus angustirostris, was described by Soviet paleotologist, Anatoly Konstantinovich Rozhdestvensky in 1947 from Mongolian fossils, in Nemegt Formation in Gobi desert.
    The 1946–1949 Soviet-Mongolian paleontological expeditions discovered the large skeleton that became Saurolophus angustirostris. The fossil is on display in paleontological Museum in Moscow.

    The Mongolian species is larger as the American one, had a longer skull and the front of the snout (the premaxillary bones) were more upwardly directed. The length dinosaur length was about 13 meters long, including 1.2 meter long skull and has estimated weight of around 11 tonnes. Aside from size, the two species are virtually identical.

    In 1998, some fossils and footprint of Saurolophus were discovered by Japanese-Mongolian paleontological expedition.

    The first discovery of dinosaur footprints in Mongolia was made by Polnish paleontologist Namnandorzhi in 1957.
    The first discovery of dinosaur footprints by Japanese paleontologists was in 1995, when the Hayashibara Museum of Natural Sciences (HMNS) — Mongolian Paleontological Center (MPC) Joint Paleontological Expedition (HMNS-MPC Expedition) discovered abundant dinosaur footprints in the Upper Cretaceous of Shar Tsav, 275 km east of Dalanzadgad, South Gobi Aimag. A total of about 18 000 footprints were discovered at Shar Tsav.

    The Hayashibara Museum of Natural Sciences, from Okayama - Mongolian Paleontological Center Joint Paleontological Expedition performed its fieldwork in the Gobi desert during the period from the mid of June to beginning of September of 1998. The main goal of the expedition was observation and acquisition of geological, geographical and paleontological data for the reconstruction of the paleoenvironments of the several dinosaur localities in the central and western part of the Gobi desert and search for fossils of prehistoric animals.
    By the 2008 field season, the HMNS-MPC Expedition had discovered 18 new dinosaur tracksites and more than 20 000 dinosaur footprints from the Upper Cretaceous of Mongolia, including some footprints of Saurolophus.

    In August 2016, joint paleontological expedition of Okayama University of Japan and the Mongolian Academy of Sciences , discovered in Gobi desert 106cm by 77cm dinosaur footprint. The footprint formed when the dinosaur walked in what was once soft ground.
    The footprint was discovered in a geological layer formed 70 to 90 million years ago and belongs to Titanosaurus.

    Titanosaur, (clade Titanosauria), diverse group of sauropod dinosaurs classified in the clade Titanosauria, which lived from the Late Jurassic Epoch (163.5 million to 145 million years ago) to the end of the Cretaceous Period (145 million to 66 million years ago). Titanosaurus, literally meaning 'titanic lizard', was named after the mythological Titans, first described by Richard Lydekker in 1877, based on fossil find in India.
    Titanosaur fossils have been found on all continents except Antarctica and include some 40 species. The group contains the largest terrestrial animals known. They are thought to have been more than 30 meters long and 20 meters tall.


    • Many thanks to fellow collectors Mr. Ruben Guzman-Gutierrez from Mexixo and Mr. Mitsuhiko Sakanoue from Japan for their help finding an information about these stamps and the dinosaurs depicted on them.
