State: Voronezh Oblast


County: Novokhopyorsky


Coordinate: 51.099998° N, 41.616669° E
Coordinate basis: stated in text

Formation: Tiraspolian Faunistic complex

Time interval: Middle Pleistocene

Max Ma: 0.78

Min Ma: 0.533

Age basis: other

Geography comments: The Novokhopersk locality is situated 1.2 km North of the city of Novokhopersk, next to the Khoper River, Voronezh region, Eastern Russia

The Novokhopersk locality has been dated to the "Tiraspolian Faunistic complex" which has been established between 0.780 - 0.533 Ma

Environment
Lithology: siliciclastic (mixed)

Taphonomic context: fluvial deposit

Habitat comments: Bed D7 is comprised of Large-medium grained sand with iron oxide, small gravel, washed carbonate concretions, mollusc shells, and "gray clayey clumps"

Bed D7 is part of the ancient alluvial deposits around this section of the Khoper River and seems to have been deposited by a rapid current close to the bank of the river

The rapid current may have washed out the faunal remains and deposited them downstream

Methods

Sampling methods: screenwash

Sample size: 1911 specimens

Sampling comments: 652 small mammal remains were recovered from Novokhopersk-1

A rich mollusc fauna was also recovered from Novokhopersk-1

Faunal remains were recovered via screenwashing with sieves of a 1 mm mesh size
