[The Epoch Times, 12 settembre 2022](Compiled and reported by Epoch Times reporter Zhang Yufei) JapanOkayama University of SciencesThe research group recentlyMongoliafromGobi desertmore than a thousand foundend of the Cretaceousfromdinosaur footprintfossil. The team said the discovery will help archaeologists understand the walking style and posture of the dinosaurs, and the results are very valuable.
According to comprehensive Japanese media reports, in June of this year,Okayama University of SciencesA dinosaur research group eMongoliaA joint investigation team from the Institute of Paleontology of the Academy of SciencesGobi desertAn investigation was carried out in the southeastern and central part of China and 23 well-preserved continuous dinosaur footprints were found. The longest “tracks” lasted about 30 meters and the total number of footprints reached more than 1,000. of which the largest footprint was 90 cm long.
Paleontologist Shinobu Ishigaki, curator of the Dinosaur Museum at Okayama University of Science, said the footprints can be traced back 70 million to 90 million years ago.end of the CretaceousIt is assumed that it was left by the herbivorous dinosaur “Titanosauria” with a body length of about 6 to 25 meters.
Ishigaki said: “These important clues help us understand the posture, movement, behavior and position of the large sauropods at the end of the Cretaceous period, and from the Titanosaurus skeleton, their legs appear to be in genu varus, commonly known as , but judging by some of the footprints found this time, they’re not all O-legs. “
Usually, the forefoot prints are easily trampled by the hindfoot and therefore difficult to leave behind, but this time it is rare to find many traces with both the forefoot and the hindfoot. Additionally, this is the first time a dinosaur footprint with footprints has been found in Mongolia.
Indeed, this joint investigation team collaborated many years ago. In August 2016 they also excavated a 106 cm long in the southeast of the Gobi Desert.dinosaur footprintFossils, presumably also left by the Titanosaurus 70 million years ago. Since footprint fossils over a meter long are rare in the world, this discovery is of great research value.

According to anotherNational GeographicIntroduction, the largest dinosaur ever found in Patagonia, Argentina, “Patagotitan mayorum”, is the largest land animal in history and belongs to the genus Titanosaur in the classification. . Its weight is equivalent to the combined weight of 12 elephants and may have reached the size limit of land animals.The fossil is fairly well preserved and helps experts understand its body structure.
