It was named for Vladimir Lenin, one of the leaders of the Communist Revolution in Russia, but not directlу: the museum where fossils is housed is located within the Lenin Memorial and Lenin school complex in Ulyanovsk; accordingly, the generic name reflects the geohistorical location of the find.
The specimen was discovered in 2012, on the banks of the river Volga near the town of Kriushi in a limestone nodule. There are several other fossils from the same time period near it, including ammonites, lamellibranchs and fish remains. Only part of the skull was found.
