A pioneer comprehensive study of several diminutive last-generation woolly mammoth teeth (M3) found on the coast of the East Siberian Sea between the mouths of the Alazeya and Malaya Kuropatoch’ya rivers was conducted. Two teeth belonged to one individual. These teeth have a similar lamellar frequency and enamel thickness as teeth of Mammuthus primigenius Blumenbach. The molar crowns from the lower Alazeya region are similar in size to those of the small Late Pleistocene–Holocene mammoths from Wrangel Island. However, the number of plates (17–19, excluding talons) is much lower than that in the teeth of typical Late Pleistocene M. primigenius (23–25). The age data of the examined teeth are beyond the limits of the 14C dating method (>45 000 years BP). Nevertheless, palaeobotanical data allow correlation of the enclosing sediments with the warm Kazantsevo Interglacial (Eemian, MIS 5e) and reconstruction of the average annual temperature, which was warmer than present-day temperatures. These conditions are confirmed by the d18O isotopes from the structurally bound carbonate in tooth enamel. The ancient landscape was wetter and more forested than modern landscapes. The diminution of M3 size and loss of posterior plateswere a result of the overall decrease in body size, likely in response to landscape change and narrowing of resource space. Mammoths from the lower Alazeya region demonstrate a stage of significant size reduction, although the dwarfing was not finalized. Their teeth are the oldest amongst the small teeth found in west Beringia.

As exemplified by other species such as forms. An example of this was the pygmy Mammuthus Palaeoloxodon and Stegodon dwarfs from the islands of exilis (Stock & Furlong, 1928), a descendant of the Sunda Archipelago (Sulawesi, Flores, Timor, Sumba Colombian mammoth that lived in North America, and Java), the landscape and remote location of the from the Channel Islands near the coast of southern isolated territory were not the only decisive factors in the California (Agenbroad et al. 1999; Agenbroad 2009; reduction of these elephants’ body size.

Remains of a dwarfed mammoth such as interspecific competition are also assumed to be referred to as M. lamarmorai (Major 1883), considered important (Crockford 2008; van der Geer et al. 2016).
