Maly Lyakhovsky Island

Maly Lyakhovsky Island consists of Upper Jurassic to lower Cretaceous turbidites, also known as flysch, covered by a thin veneer of Pliocene to Pleistocene sediments.

These Mesozoic rocks consist of sandstones, argillites, and shales deformed into east-northeast striking folds about 7 to 20 km (4.3 to 12.4 mi) wide.

The Mesozoic rocks are covered by a relatively thin layer of Pliocene to Pleistocene sandy and clayey sediments of colluvial and alluvial origin.

[2][3][4] On 29 May 2013, an expedition of North-Eastern Federal University found the remains of a 10,000-year-old carcass of a female mammoth on Maliy Lyakhovsky Island.

It was reported that liquid blood was found in ice cavities below the belly even though the temperature at the time of excavation was −7 to −10 °C (19 to 14 °F).
