Dinosaur tracks at the Nemegt locality: Paleobiological and paleoenvironmental implications

摘要: Abstract The Nemegt locality is one of the most famous dinosaur localities in Mongolia ever since site was discovered 1946. It yields abundant skeletons; however, little attention had been given to footprints at locality. only footprint study focused on descriptions footprints, gave a few taxonomic implications, and provided no comparison with other tracksites. This reports newly recorded (hadrosaurs, sauropods, theropods) during Educational Expedition 2016. A single footprint-bearing horizon that extends several kilometres examined within Formation determine ichno-taxonomic assemblage dinosaurs. significant difference identified between compositions based skeletal remains footprints. Although vast majority elements collected area belong theropods, suggest dominated by herbivorous suggests previously inferred Tarbosaurus dominant composition result preservational bias. size distribution studied hadrosaurs an adult-dominant multigenerational population structure. Comparisons tracksites Cantwell (Alaska, USA) Tremp (Spain) formations show structure body sizes were similar those high-latitude hadrosaurs. more open higher plant productivity than area.
