Comment:
In 1998, we were able to collect at the Bykovsky Peninsula more than 600 bones. Typically for permafrost regions, where fossil bones in summer rapidly emerge from frozen sediment and are delivered to the cliff foot by mud flows, most bones come from the shore and shallow coastal bars, mainly in the area of the Mamontovy Khayata cliff, and another site NW of it, provisionally called ”the Holocene Shore”. However, rather large amount of bones (145) was collected at the Mamontovy Khayata exposure itself. Among them, about 20 bones (location group ”a”) were discovered strictly in situ in the frozen silts and sands, and about 80 bones were found in the mud flows; the initial stratigraphic posi-tion of the latter could be reconstructed more or less precisely (location group ”b”). About 30 bones, listed under the last group, were found on the surface of fresh mud flows evidently related to certain baidzherakhs, or their closely ar-ranged groups, so the original position of these bones can be estimated within 2-4 meters of the baidzherakh height. The other bones, listed under the group ”b”, were found (sometimes in rather high concentrations) on the mud flows related to large exposed parts of the cliff, usually at the base of its upper steep part. The areas of these concentrations are labelled here as ”bone fields”; the possible altitude range of the original position of bones was usually estimated between the height of their occurrence (minimum) and the height of the cliff in this particular area (maximum). The bones referred to the location type ”c” have been found within the Mamontovy Khayata cliff, but their exact position remains unknown. Nearly 300 bones (group ”d”) were collected at the Mamontovy Khayata shore and on the more or less adjacent shallow bars emerging during the lower sea level conditions. About 150 bones were picked up at the ”Holocene Shore” (group ”e”). Finally, a few dozens of bones come from the other sites on the Bykovsky Peninsula (mostly NW from the Mamontovy Khayata), and a few specimens have been delivered from other locations in the Lena Delta (group ”f”).
