Sanj talks about the collection of Kalmyk skulls stored at the Moscow State University and a genetic project that he did in 2007. He says that the collection is stored at the Anthropological Museum of the Moscow State University. This collection may include skulls that belonged to Khoshud individuals. There is a research published on this collection in 1937 by Levin and Trofimova. Apart from that, there is no other research available on the anthropological characteristics of the Khoshuds. One of the first genetic researches on the Kalmyks was done in 1991, resulting in several articles. In 2007, Sanj studied 100 Khoshuds by taking their photos and blood samples. He argues that the Khoshuds consist of three haplogroups.
