Subfossil remnants of Black Guillemot from Western Spitsbergen
Abstract:
Two subfossil bones of auk (complete humerus and incomplete ulna), dated back to Late Holocene, were found in moraine gravel in Western Spitsbergen in 1975. Both of them belonged to young bird and have been determined as Black Guillemot. Proportions of the humerus and especially the sizes of the bone shaft cross-section in the midd-length are nearly identical as in the birds living now in the Spitsbergen Archipelago, belonging to the subspecies Cepphus grylle mandti (Mandt 1822).
