Tarchia (meaning "brainy one") is a genus of herbivorous ankylosaurid dinosaur from the late Cretaceous of Mongolia.
Discoveryandnaming
In 1970, a Polish-Mongolian expedition discovered an ankylosaurian skull near Khulsan.
In 1977, Teresa Maryańska named and described the type species Tarchiakielanae. The generic name is derived from Mongolian tarkhi, "brain" and Latin ~ia, in reference to a brain size presumed larger than that of the related form Saichania. The specific name honours Professor ZofiaKielan-Jaworowska, the leader of the expedition.
The holotype, ZPalMgD-I/111, was discovered in the Upper Cretaceous (possibly Campanian-Maastrichtian) BarunGoyot Formation (previously known as the 'Lower Nemegt Beds') of the Nemegt Basin of Mongolia. It consists of a skull roof, braincase and rear skull elements.[1] Maryańska referred three additional specimens: ZPAL MgDI/43, a large postcranial skeleton containing three "free" tail vertebrae, twelve tail vertebrae of the "handle" of the tail club and a scute; ZPAL MgDI/49, a right humerus; and PIN 3142/251, a skeleton with skull, that as yet remains undescribed.
