ZHANNA ANTIPUSHINA
Profile ADK-009
56 – 107 cm Layer II
56 – 64 cm Fine-grained material: compressed, ductile, adhesive, saturated with crashed shells. The thickness of this layer is decreasing toward to right
corner, the stratigraphy is getting disrupted.
64 – 107 cm Heterogeneous layer: sea urchin plates prevail in the upper part of it, charcoal streaks are found at the depth of 71 – 73 cm and 93 – 97 cm,
gastropod shells appears below 99 cm.
107 – 123 cm Layer III
107 – 112 cm Fine-grained material: brown, wet, ductile, adhesive, saturated with bones.
112 – 123 cm Layer of crashed shells and sea urchin plates, almost without fine-grained material.
123 – 140 cm Layer IV
123 – 128 cm Brown fine-grained material saturated with crashed shells and bones.
128 – 140 cm Heterogeneous layer of midden: crashed shells and fine-grained material constitute the upper part of it, the lens of see urchin plates is found in
the right corner.
140 – 166 cm Layer V
140 – 150 cm Brown fine-grained material saturated with crashed shells and bones.
150 – 166 cm Light-brown fine-grained material, unstructured, adhesive, with sparse grains of clastic ash. The upper 5 cm of it are darker, saturated with bones only.
166 – 173 cm Underlying bedrock
The molluscs from these shell middens include:
6 species of chitons (Polyplacophora), 22 species
of gastropods (Gastropoda) and 12 species
of bivalves (Bivalvia) (Table 1). Among these species
the following were the most frequent species
in the sample: a foolish mussel Mytilus trossulus, a
Nuttall’s cockle Clinocardium nuttallii, a limpet
Lottia pelta, a periwinkle Littorina sitkana, and a
chiton Katharina tunicata (Table 2).
According to ethnographical data, these shellfish
species were important as food resources for
Aleutians (Zubkova 1948, McCartney 1975,
Veniaminov 1984).
There were identified 2500 mollusc remains at
ADK-171. Bivalves dominate the sample followed
by gastropods and chiton remains.
The analysis shows that mollusc taxonomic
composition changed significantly during the existence
of the ancient settlement (Fig. 2). The foolish
