Deinocheirus mirificus
Deinocheirus is a genus of very large ornithomimosaurian dinosaur that lived in what is now southern Mongolia during the late Cretaceous period around 70 million years ago. The genus Deinocheirus contains one species, Deinocheirus mirificus. D. mirificus was long thought of as a very mysterious dinosaur, known only from a set of gigantic fossil arm bones. The discovery of more complete skeletons helped to solve this longstanding mystery, revealing a very strange, giant, bipedal omnivore. Deinocheirus mirificus was a large ornithomimosaurian, measuring up to 11 m (36 ft) long, and with an estimated upper weight of 6.358 t (6.258 long tons; 7.008 short tons). Though it had many of the typical skeletal features of its group, its overall appearance was very different from its relatives. While other ornithomimosaurians were light and fleet-footed, Deinocheirus had evolved to outsize its predators, and effectively became slower and bulkier.
Tarchia gigantea
Tarchia (meaning "brainy one") is a genus of ankylosaurid dinosaur from the late Cretaceous of Mongolia. It is currently the geologically youngest known of all the Asian ankylosaurid dinosaurs and is represented by five or more specimens, including two complete skulls and one nearly complete postcranial skeleton. It was discovered in the Upper Cretaceous (possibly Campanian-Maastrichtian) Barun Goyot Formation (previously known as the 'Lower Nemegt Beds') of the Nemegt Basin of Mongolia. It had a bony tail club, like many ankylosaurids. Tarchia is one of the largest known Asian ankylosaurs, with an estimated body length of 8.5 metres (27.9 ft), a skull length of 40 centimetres (16 in), and skull width of 45 centimetres (18 in). Tarchia may have weighed as much as 5 tonnes. Named for its massive skull (Mongolian tarkhi meaning 'brain' and Latin ia), Tarchia currently includes only the type species, T. gigantea. The rocks in which they were found likely represent eolian dunes and interdune environments, with small intermittent lakes and seasonal streams. Hence, we know that Tarchia was a desert animal. The morphology of cranial sculpturing seen in Tarchia, an assortment of bulbous polygons, is reminiscent of that of Saichania chulsanensis, another ankylosaurid from the Barun Goyot Formation.
