Manganese Staining Coverage Percent

Aggregate caller identified manganese stain coverage from bone masks with physical pixel-area correction; staining chemistry, mineral identity and depositional history remain external.

Description

Stained bone coverage needs an observable bone mask.

Stained bone coverage needs an observable bone mask. Physical pixel areas matter when images use different scales.

Aggregate caller identified manganese stain coverage from bone masks with physical pixel-area correction; staining chemistry, mineral identity and depositional history remain external.

When to use Manganese Staining Coverage Percent

Use this tool to aggregate caller identified manganese stain coverage from bone masks with physical pixel-area correction; staining chemistry, mineral identity and depositional history remain external.

Prepare the fossil measurements or occurrence records and the chosen calibration parameters. Retain the stated coordinate, age and measurement conventions.

How to use Manganese Staining Coverage Percent and understand its results

Prepare the fossil measurements or occurrence records and the chosen calibration parameters. Retain the stated coordinate, age and measurement conventions.
Enter stainedPixelCounts, observableBonePixelCounts, pixelAreasMm2 using the field table and calculation rules, then run the tool.
Read perSpecimenStainedCoveragePercent, pooledPhysicalAreaStainedCoveragePercent. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
stainedPixelCounts	Stained pixel counts	list of number	Required
observableBonePixelCounts	Observable bone pixel counts	list of number	Required
pixelAreasMm2	Pixel areas mm2	list of number	Required

Align nonnegative integer stain counts, positive integer observable counts and positive pixel areas. Require stained no greater than observable; return local and physical-area-weighted percentages.^[1]

Paired lists must be nonempty and have equal lengths.

pooled stain percent = 100 × Σ stained pixels × pixel area/Σ observable pixels × pixel area

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
perSpecimenStainedCoveragePercent	Per specimen stained coverage percent	list of number
pooledPhysicalAreaStainedCoveragePercent	Pooled physical area stained coverage percent	number

Limitations and assumptions

Mask attribution does not identify mineral chemistry or depositional history.

Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Trampling Mark Misidentification Flag Checker: Apply explicit caller shallow-mark/intersection confound screen; a flag preserves uncertain mark attribution and is not an automated trampling or cut-mark diagnosis. For a complementary task, use Coprolite Phosphatic Content Bulk Estimate: Report a background-corrected equivalent phosphate-mineral mass on caller phosphorus stoichiometry; signed nondetections and values above physical mass fraction are model diagnostics, not actual mineral identification or coprolite authenticity.
