Er-lianhaote Dinosaur National Geopark, Inner Mongolia
This national geopark is located in Er-lianhaote, Inner Mongolia Autonomous Region, and has a total area of 70 km2. It was approved by the Ministry of Land and Resources as a national geopark in August 2009. Cretaceous dinosaur fossils are the major attractions because they were first discovered and studied in this geopark. Many kinds of Late Cretaceous dinosaur fossils found here represent the biota in Asia 80 million years ago, including sauropods, archaeornithomimus, gallimimus, alectrosaurus, bactrosaurus, Xilingol gilmoreosaurus, ankylosaurus, neimongosaurus, erliansaurus, and gigantoraptor. The Er-lian Yanchi Iren Dabasu Formation geologic cross-section, which shows the Upper Cretaceous strata, is considered by palaeontologists to be the standard section of the late Cretaceous. It contains fossils of dinosaurs, ostracods, and associated vertebrates.
