Lakhuti 2 Main collection (Pleistocene of Tajikistan)

Also known as Lakhuti-2 main

Where: Tajikistan (38.3° N, 70.0° E: paleocoordinates 38.4° N, 69.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kayrubak Member, Pleistocene (2.6 - 0.0 Ma)

• "the mammal remains originate from the silty inter-layers of the pebble-silty deposists of teh Kayrubak suite". At Lakhuti 2 main the bones are "associated with brown inter-layers of calcareous water-lain silts". "The pebble-silts of the Kayrubak formation are 13-14m thick here. They lie above the Jaramillo event and below the Brunhes/Matuyama boundary" (ie. between 1.0-0.78Ma). Lenticular accumulations of bones are found from the waterline to 2m above it and can be traced 60-70m along the bank.

Environment/lithology: fluvial-lacustrinelenticular, brown, silty, calcareous

• Bones are found in the Kayrubak suite which unconformably overlies Lower Pliocene red sandstones and underlies thick Pleistocene loesses containing many fossil soil horizons.
• At Lakhuti 2 main the bones are "associated with brown inter-layers of calcareous water-lain silts, which replaces the grey-green silts of the preceding locality" (Lakhuti 2 point). "The pebble-silts of the Kayrubak formation are 13-14m thick here. They lie above the Jaramillo event and below the Brunhes/Matuyama boundary" (ie. between 1.0-0.78Ma). The lenticular accumulations of bones are found from the waterline to 2m above it and can be traced 60-70m along the bank.

Size classes: macrofossils, mesofossils

Collection methods: bulk,

• Fossils were discovered in the 1950s and excavated from 1968 onwards by the Physics Institute, the Geological Institute and the Palaeontological Institute, the USSR Academy of Sciences and the Institute of Zoology and Parasitology, the TajikSSR Academy of Sciences.
