Lithology and environment

| Lithology description: "The sediment immediately below and ancasing the carcass is composed of banded silt and silty clay composed predominantly of quartz." "...Intimately associated with the skeleton is a prominent discontinuous layer from 1-2 mm thick containing a black (N2.5/0) mineral... This black layer is composed of small tubules and strands that we interpreted to be hair." (pp. 103-104) | |
