The GeoSciML Fossil package contains classes for representing Fossils. These may be: FossilMold or TraceFossil. They are linked to living or once living things by the Organism class. It is recommended that a fossil(s) behaving as a "material" should be described asa "constituent part" of an earth material. v2.0.1 - all links to elements in GMD namespace 'by reference' v2.0.2 - inserted XML declaration A fossil that is a negative image of some organism or part of an organism. Considered a structure because the mold has the same relationship to its material substrate that a geologic structure does--the mold is in the substrate, it is not the substrate itself. Specifies the related Organism that produced the fossil in the original substrate material A sedimentary structure produced by the life activities (other than growth) of some organism. Neuendorf et al. (2005) restrict to structures produced by animals; further consideration needed on how to deal with structures produced by other life-forms. Specifies the related Organism that produced the fossil in the original substrate material Broad class to represent any living or once living thing. This is the connection to taxonomy/biology for fossils.
