The findings, published in <a href=\"http:\/\/dx.doi.org\/10.1016\/j.cretres.2024.106046\">Cretaceous Research<\/a>, after a detailed analysis of a partial neck vertebra found in Kumamoto Prefecture, shed light on the diversity and evolution of these ancient flying reptiles in East Asia.<\/p>\n\n\n\n<p>The fossil, originally unearthed in the 1990s in the Mifune Group geological formation, was re-examined using advanced CT scanning and phylogenetic analysis. The study revealed that&nbsp;<em>Nipponopterus mifunensis<\/em>&nbsp;belongs to the Azhdarchidae family, a group that includes some of the largest flying animals in history. With an estimated wingspan of 3 to 3.5 meters, this pterosaur lived during the Turonian\u2013Coniacian stages of the Late Cretaceous, making it one of the earliest known members of its lineage.<\/p>\n\n\n\n<p>The sixth cervical vertebra of&nbsp;<em>Nipponopterus<\/em>&nbsp;displays unique features, such as a prominent dorsal keel, a ventral sulcus (a long groove on the underside), and an unusually positioned postexapophysis. These traits distinguish it from other known azhdarchids and place it within the Quetzalcoatl subfamily, closely related to the North American&nbsp;<em>Quetzalcoatlus<\/em>&nbsp;and a mysterious Mongolian specimen.<\/p>\n\n\n\n<p>Dr. Naoki Ikegami from the Mifune Dinosaur Museum emphasized the significance of the discovery: \u201cThis is a major step forward for Japanese paleontology. Until now, no pterosaur had been formally named from skeletal remains found in Japan. This discovery provides crucial new insight into the diversity and evolution of pterosaurs in East Asia.\u201d<\/p>\n\n\n\n<p>The fossil of&nbsp;<em>Nipponopterus mifunensis<\/em>&nbsp;is now on display at the Mifune Dinosaur Museum, offering the public a rare glimpse into Japan\u2019s prehistoric skies. This discovery not only fills a gap in the fossil record but also highlights the global distribution and evolutionary history of azhdarchid pterosaurs. Future research may uncover more about their behavior and ecological role in ancient ecosystems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A team of international researchers has identified a new species of pterosaur,&nbsp;Nipponopterus mifunensis, marking the first time a pterosaur has been formally named based on body fossils discovered in Japan.
