Conservation note: The mineral marcasite
(orthorhombic iron disulfide, FeS2) is
present in some of the fossils and
matrix. It may be visible as a dark
brassy material in cavities of bones, as
above, natural size, and 4 x
magnification. More often it exists as a
greenish black component in matrix, where
it can be recognized by the persistant
sulfur odor. Mineral and rock specimens
containing marcasite often tarnish,
corrode, and crumble over several years
or decades. Measures will need to be
taken to assure this does not happen.
