Altirhinus kurzanovi

(Kurzanov's high nose) Etymology
Altirhinus is derived from the Latin "altus" (high) and the Greek "rhin-(rhis)" (nose or snout) named "in recognition of the highly arched nasal bones of the skull which give the snout of this animal a distinctively elevated profile." The species epithet, kurzanovi (koor-zuh-NOH-vie), is named in honor of Dr. Sergei M. Kurzanov of the Paleontology Institute of the Russian Academy of Sciences, Moscow.
Discovery
The remains of Altirhinus were discovered in the Khuren Dukh Formation (previously part of the Shinekhudag/Shinehuduk Formation), 80km south of Choiren railway station, Dornogovi Province, Mongolia, by Kurzanov in 1981. The holotype (PIN 3386/8) includes a skull which is well preserved on the left side, plus bits of hands, feet, shoulders and hip. All remains were originally assigned to Iguanodon orientalis.
