Scholars from the Sino-German Footprint Expedition recently announced that they have discovered the largest group of early Jurassic lizard footprints in China in the town of Maotai, Guizhou Province.
this discovery is of great significance for the study of the distribution and evolution of dinosaur fauna in the early Jurassic period in China.
the remains of lizard-footed dinosaurs, an important branch of dinosaurs, have been found on all continents, but the discovery of these footprints was a complete surprise.
it is understood that the group was found at a winery construction site in Maotai Town in the summer of 2013, and in the summer of 2017 the company's employees informed Associate Professor Yan Lida of the China University of Geosciences (Beijing) that it had been confirmed to be a presence of early Jurassic lizard-footed dinosaurs. "I was very excited when I saw the photos provided by the staff of the winery, "
.
" Yu Lida recalls, "the dinosaur trails are very narrow, claw marks are long, this is a typical early lizard foot characteristics, but also in Yunnan Lufeng and other places found such bone fossils."
" he said, Maotai town found the largest dinosaur footprint fossils about 40 cm long, about 30 cm wide, toe depth of about 5-6 cm.
at least 250 dinosaur footprints on the scene, about 180 to 190 million years ago.
interesting, there are some special extended toe marks on the footprints, which scholars have speculated may be the lizard-footed swim.
this extremely rare footprint indicates that the area was flooded at some point, with some lizard-footed dinosaurs swimming through the area, with their toes scraping to the ground and leaving footprints.
it is understood that the early Jurassic dinosaur footprints are very rare, the domestic Jurassic early lizard foot footprints only Sichuan Ancient, Zigong Fushun, Chongqing Dafoot and Guizhou Bi festival 4, and these footprints have traffic inconvenience, severe weathering, rare number or difficult to protect, and this newly discovered footprint group to save well, a large number, has important scientific research value.
at present, the team is in communication with the relevant parties to develop protection plans, so that this footprint group is better protected and more valuable.
