[Geology2] Rare 3D dinosaur footprints found in Chongqing

Rare 3D dinosaur footprints found in Chongqing
Xinhua News Agency [China], 2010-06-17

The China-U.S. Science Expedition recently found a number of rare
three-dimensional dinosaur footprints when they were investigating and
researching dinosaur footprints in the Lianhuabao Village of Qijiang
County, southwest China's Chongqing Municipality. Experts said the
discovery of the three-dimensional dinosaur footprints helps scientist
understand the way dinosaurs walk. At present, experts are further
investigating and researching these footprints. The group of dinosaur
footprints was found in Lianhuabao Village in 2003 and is currently the
largest from the cretaceous period. There are more than 300 dinosaur
footprints, including concave and convex footprints, distributed in an
area of 140 square meters and they belong to the Ankylosaurus,
Anatosaurus and Theropoda. During their research, the experts found that
some well-preserved convex dinosaur footprints have three toes, with a
mound-shaped metatarsal print at the heel and a hoof-shaped claw print
at each toe. The footprints are half a meter long and are much longer
than those found in the past which were only a few centimeters long. The
study shows that these footprints are really 3D dinosaur footprints that
belong to the Hadrosaurus.
