Description
Bioerosion trace density records independently identified traces per inspected surface area.
Bioerosion trace density records independently identified traces per inspected surface area.1
Surface density differs from volume abundance and depends on consistent inspection criteria.
When to use Bioerosion Trace Density per dm2 Calculator
Use this tool to apply the stated bioerosion trace density per dm2 calculator operation with an explicit input and unit basis.
How to use Bioerosion Trace Density per dm2 Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualIndependentlyCountedBioerosionTraceCount, actualInspectedSurfaceAreaDm2 and run the tool.
- Read result.value using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualIndependentlyCountedBioerosionTraceCount | Independently counted bioerosion trace count, on the basis specified in the algorithm. | number | required; finite; integer from 0 to 1000000; further conditions in the algorithm |
| actualInspectedSurfaceAreaDm2 | Inspected surface area dm2, on the basis specified in the algorithm. | number | required; finite; strictly positive; further conditions in the algorithm |
Require integer trace count 0–1,000,000 and positive inspected area in square decimeters. Divide traces by area.
density = trace count / inspected dm² Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Counted bioerosion traces per square decimeter. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
For a related operation, use MNI from Most Common Element Calculator. Minimum-number-of-individuals accounting uses paired elements to establish a lower bound within a resolved taxon and context.
For a related operation, use Dinosaur Bonebed Monospecificity Percent Checker. A focal taxon's specimen fraction measures its share of a taxonomically resolved bonebed inventory.
