Maly Lyakhovsky Island
Maly Lyakhovsky Island ((ロシア語:Малый Ляховский)) is the second largest of the Lyakhovsky Islands belonging to the New Siberian Islands archipelago in Laptev Sea in northern Russia. It has an area of .
The Lyakhovsky Islands are named in honour of Ivan Lyakhov, who explored them in 1773.
==Geology==
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 wide. The Mesozoic rocks are covered by a relatively thin layer of Pliocene to Pleistocene sandy and clayey sediments of colluvial and alluvial origin. Near the coast, the alluvial sediments grade into nearshore marine sediments containing fossil marine mollusks and lignitized wood. Thick permafrost characterized by massive ice wedges has developed in these sediments.〔Fujita, K., and D.B. Cook, 1990, ''The Arctic continental margin of eastern Siberia'', in A. Grantz, L.

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. It was speculated that this find might reveal information about the cryoprotective properties of mammoth blood. The mammoth remains were taken to Yakutsk in Sakha Republic, Russia, for bacterial examination and tissues analysis, especially for a joint project of NEFU and Sooam Biotech Research Foundation in cloning a mammoth.〔Lupanov, N (2013) (''Sensational discovery: NEFU scientists have discovered a female mammoth.'' ) North-Eastern Federal University in Yakutsk.〕
