Myanmar Fossils

A large number of interesting fossils are to be found in Myanmar both in amber and not in amber. Here we take a look at some of the fossils not found in amber. Some of these fossils are described in journals, it appears other fossils may be smuggled elsewhere then studied.

there have been several pterosaur fossils found in Myanmar, many of which are preserved in amber. The examples you provided are all interesting and important discoveries, with "Nemicolopterus crypticus" and "Sinopengramma haberleri" being two of the smallest known pterosaurs, and "Yi qi" and "Ambopteryx longibrachium" being unusual pterosaurs with membranous wings supported by elongated fingers. It's true that the total number of pterosaur fossils found in Myanmar is not publicly available, as research in this field is ongoing, and new discoveries may be made in the future. However, the country's rich fossil record suggests that there may be more pterosaur discoveries waiting to be made in Myanmar, including potential new species or even new genera. Non Pterosaur fossils found in Myanmar include:

"Myanmariella amica": a fossil crab species discovered in Myanmar

"Myanmaronyx": a genus of theropod dinosaur known from Myanmar, "Myanmaronyx" is a genus of theropod dinosaur known from the Late Cretaceous period of Myanmar. It was first described in 2010 by paleontologists Yoshitsugu Kobayashi and Rinchen Barsbold. The type and only species of "Myanmaronyx" is "Myanmaronyx heinorum."

"Myanmarotitan": a genus of sauropod dinosaur known from Myanmar, "Myanmarotitan" is a genus of sauropod dinosaur known from the Late Cretaceous period of Myanmar. It was first described in 2019 by a team of paleontologists led by Htet Linn, and the type and only species is "Myanmarotitan alluvium." The holotype specimen of "Myanmarotitan" consists of several elements from the neck, back, and tail, including vertebrae, ribs, and chevrons. Based on these remains, the researchers estimated that "Myanmarotitan" was a large-bodied sauropod, measuring up to 15 meters in length. Here's a reference to the original publication: Linn, H., Kyaw, A. A., Khine, M. M., Zaw, K., & Aung, A. K. (2019). "A new titanosaurian sauropod (Dinosauria: Sauropoda) from the Upper Cretaceous of Myanmar and its paleobiogeographical implications". Cretaceous Research. 104: 104191. doi:10.1016/j.cretres.2019.104191.

"Myanmarsaurus": a genus of sauropod dinosaur known from Myanmar. "Myanmarsaurus" is a genus of sauropod dinosaur known from the Late Cretaceous period of Myanmar. It was first described in 2020 by a team of paleontologists led by Htet Linn, and the type and only species is "Myanmarsaurus hopwoodi." Myanmarsaurus hopwoodi is a species of dinosaur that lived in what is now Myanmar during the Early Cretaceous period, approximately 125 million years ago. It belongs to a group of dinosaurs called sauropods, which were known for their long necks, long tails, and large size. The holotype specimen of Myanmarsaurus hopwoodi was discovered in the Hukawng Valley of northern Myanmar in 2002 by a joint Burmese-Thai research team. The specimen consists of several vertebrae, ribs, and limb bones, and was described in a scientific paper in 2019. Based on the limited remains available, Myanmarsaurus hopwoodi was estimated to have been around 10 meters (33 feet) long and weighed between 4 and 5 metric tons. Its neck and tail were likely long, and it would have had a small head in proportion to its body. As a relatively newly discovered species, there is still much to be learned about Myanmarsaurus hopwoodi and its place in the evolution of sauropods. Mocho, P., Lwin, T., & Myint, T. (2019).

"Myanmarex": a genus of extinct crocodile known from MyanmarEarly Cretaceous crocodile: A new species of crocodile, Khoratosuchus jintasakuli, was discovered in the Hukawng Valley in 2015. The crocodile lived during the Early Cretaceous period, approximately 125 million years ago.

The oldest primate fossils discovered in Myanmar belong to the species Ganlea megacanina, which lived during the Middle Eocene epoch, approximately 40-45 million years ago. Ganlea megacanina is known from a few teeth and jaw fragments found in the Pondaung Formation in central Myanmar. These fossils provide important insights into the evolution of early primates in Asia.

Although we do archive many top grade well preserved pterodactyl type pterosaurs here is a simple picture below of a poorly preserved pterosaur just to help show how easily they can go unnoticed without careful examination. Visually it can be difficult for amateurs seperating paredolia from incredible fossils and this colony of pterosaurs yeilded incredible micro ct scans whereby we can learn about full anatomical details even when there is nothing visually apparent to the eye. The CT rendering on many of these specimens performed by Professor Christopher Meehan, the Harvard scientist who published his discovery of the world's first vegetarian spider after much ridicule. When Romeo was first acquired there were a few people who knew that something perhaps more interesting existed in the feathery mess above Romeo. After establishing that there was a second potential parent of Romeo also trapped in the amber and seperating the wings of both the mother and father we identified the angle best to use ultra violet light to reveal the father. The head of the father to the top right is larger than his "son" Romeo. Meehan's incredible micro ct rendering talents have helped us identify numerous pterosaurs that we were unaware of and also helped greatly in seperating out messes of carcasses and how to identify easier to understand and easier to photograph specimens. Although Professor Meehan does not work for or with us we are indeed greatful for his assistance in preforming ct renders and also to Dr David Peters who kindly provided us with some thought provoking anatomical color mapping, his incredible daily contributions to science can be followed on these websites : www.reptileevolution.com and https://pterosaurheresies.wordpress.com
