KEY TO ORGANIC MATTER
1. organic fragment composed of more than 5 connecting cells,
1.1. belonging to more than one tissue type
: organ residue (specify type
of organ);
1.2. other, composed of only one type of tissue:
tissue residue (specify type
of tissue)
2. other organic fragments composed of groups of 5 or less interconnected cells or individual cells: cells
3. other areas of holo-organic matter without recognizable cell structure amorphous organic fine material.
3.1. amorphous organic fine material of uniform
colloidal texture, with less than 5% inclusion of coarser organic elements,
showing desiccation cracks in sections of air dried material: monomorphic
material
3.2. other amorphous organic fine material with
more than 5 % coarser organic elements included: polymorphic
material
4. other organic material occurring as very dark or opaque grains of about 1 mm in the inorganic micromass: punctuations
5. other organic material staining the inorganic micromass: organic pigment
