The 170 million-year-old two-toed dinosaur footprints have been found in iran's Mid-Jurassic formations.

BEIJING, July 12 (Xinhua Xie Hong) 12, China and Iran and other countries paleontology in Beijing announced that they found in northern Iran's Erbuls Mountains region of the Mid-Jurassic dinosaur footprints, which means that a class of feathered ferocious dinosaurs once roamed the Iranian land 170 million years ago.
Associate Professor Yan Lida of The University of Geology of China (Beijing), Associate Professor Nasrallah Abrasi of Zanjan University in Iran, and Professor Martin Lockley, Director of the Footprint Museum at the University of Colorado, USA, described the footprint specimens in a recently published issue of The Journal of Historical Biology.
" Balady's footprint is great! They are very 'fresh' and have only been exposed in recent years when roads have been built, which is very beneficial to our research.
"Abass introduced, "the footprints here are mostly round lizard foot footprints, three-toed carnivorous dragon footprints, but, in an expedition with Lida, we unexpectedly found two small footprints in the mountainside, footprints are very small, less than 10 cm long."
is that these small footprints have only two toes.
" two-toed dinosaurs refer to the most famous members of the Python species, the dragons (a.g., the dragons) that starred in the Jurassic Park series, all of which had large spring-like second-toes, which were the "killers" they hunted.
interestingly, the toes did not come into contact with the ground when the dinosaurs normally walked, leaving behind two-toed footprints, collectively known as claw-like footprints.
"In the early 1990s, the footprints of the dragons were first discovered in Sichuan, China, but the footprints were very few, only a few, " said Yu Lida, since then, China's Shandong, Gansu, Sichuan, southern South Korea and other places have been found, but these footprints are basically published in the early Cretaceous, individual in the late Jurassic, Iran's discovery set a new record, the distribution of such dinosaur footprints in the world ahead of the middle of the world.
the discovery echoes the fossil record in northeastern China.
Chinese palaeontologists have discovered a wealth of vertebrates, invertebrates and plant fossils, known as the Yanliao biota, in the Mid-JurassicGeorge and Kowloon Mountains groups.
a number of chilong dinosaurs have been discovered in the Yanliao biome, although they are tree-dwelling, but the two-toed foot type is very obvious.
" Interestingly, Iran's python footprints show that their creators are about 1 meter long, which is more in line with the records of China's Yanliao biome and subsequent hot river biomes.
