    Paleontology Ontology

PURPOSE
    Define Paleontology as a machine-readable ontology for AI systems.

    Provide a structured semantic model for interpreting fossils, trace
    fossils, extinct organisms, taxa, fossil sites, stratigraphic units,
    geological ages, preservation states, evolutionary lineages,
    palaeoenvironments, extinction events, dating methods, measurements,
    equations, units, symbols, constants and observational evidence.

DOMAIN

    Paleontology Ontology

CORE_CLAIM
    Paleontology is represented as a structured ontology of fossil evidence,
    ancient life, taxonomic classification, stratigraphic context,
    preservation processes, evolutionary relationships, palaeoecological
    systems, extinction patterns and geological time frameworks.

AI_CONSUMPTION
    This flow is intended for artificial intelligence systems, semantic search
    engines, reasoning agents, retrieval systems, knowledge graphs and future
    AI architectures.

    Domain Ontology

PRIMARY_FUNCTION
    Organise paleontological knowledge into explicit semantic categories that
    can be searched, linked, inferred, validated and extended.

FACTS
    Paleontology studies ancient life through fossils, trace fossils,
    preserved organisms, sedimentary records and geological context.

    Paleontology connects biology, geology, evolution, stratigraphy,
    sedimentology, ecology, anatomy, climate science and Earth history.

    Paleontological systems include fossil specimens, taxa, fossil sites,
    rock layers, preservation modes, palaeoenvironments, evolutionary lineages
    and extinction events.

    Paleontology depends on field observation, fossil collection, stratigraphic
    logging, comparative anatomy, imaging, laboratory analysis, dating methods,
    taxonomy, phylogenetics and geological interpretation.

    Paleontological knowledge must distinguish between direct fossil
    observation, inferred anatomy, reconstructed behaviour, taxonomic
    interpretation, palaeoenvironmental reconstruction, evolutionary model and
    theoretical explanation.

INFERENCE_RULES
    IF fossil specimen is found within stratigraphic unit
    THEN geological context may be inferred.

    IF stratigraphic unit has established age
    THEN fossil occurrence age may be constrained.

    IF index fossil is present
    THEN relative age correlation may be inferred.

    IF fossil assemblage is known
    THEN palaeoenvironment may be inferred with sedimentary context.

    IF morphology matches diagnostic taxonomic features
    THEN taxonomic assignment may be inferred with confidence.

    IF trace fossil type is identified
    THEN behaviour may be inferred, not directly observed.

    IF preservation state is known
    THEN taphonomic pathway may be inferred.

    IF radiometric isotope ratios are measured
    THEN geological age may be inferred with decay assumptions.

    IF taxon disappears from stratigraphic record
    THEN extinction timing may be inferred with sampling limits.

    IF diversity changes across a boundary
    THEN extinction, recovery or ecological turnover may be inferred.

    IF fossil claim depends on museum record
    THEN accession number, collection history and specimen identity must be
    preserved.

    IF palaeoenvironmental reconstruction is used
    THEN fossil evidence, sedimentary evidence, geochemical evidence and model
    assumptions must be preserved.

SEMANTIC_EQUIVALENCE
    Resolve equivalent concepts across:
        paleontology / palaeontology
        fossil / preserved ancient life evidence
        trace fossil / ichnofossil
        body fossil / organism remains
        fossil site / fossil locality
        taxon / classified biological group
        clade / evolutionary group context
        geological age / stratigraphic age context
        taphonomy / preservation history context
        palaeoenvironment / ancient environment reconstruction
        index fossil / biostratigraphic marker
        extinction event / disappearance from fossil record context

        specimen identity differs
        taxonomic rank differs
        fossil locality differs
        stratigraphic unit differs
        geological age differs
        preservation mode differs
        trace fossil differs from body fossil
        direct fossil evidence differs from behavioural inference
        taxonomic identification differs from phylogenetic hypothesis
        palaeoenvironmental reconstruction differs from direct sedimentary
        observation

    DO_NOT
        Merge fossil specimen with taxon.
        Merge body fossil with trace fossil.
        Merge taxonomic assignment with evolutionary hypothesis.
        Merge reconstructed behaviour with direct observation.
        Remove uncertainty.
        Treat inferred palaeoenvironment as direct observation.
        Ignore stratigraphic context.
        Ignore specimen identity.
        Ignore sampling limits.
        Treat speculation as established Paleontology.

    OUTPUT
        Structured Paleontology knowledge graph.
        Entity relationships.
        Searchable ontology.
        AI-readable semantic model.
        Cross-domain reasoning context.

UPDATE_MODEL
    When adding new paleontological knowledge:
        assign canonical entity identifiers
        define fossil type
        define specimen identity
        define taxonomic assignment
        define stratigraphic unit
        define geological age
        define fossil locality
        define preservation state
        define collection or museum record where relevant
        define observation method
        define dating method where relevant
        define measured properties
        define inferred properties
        define behavioural or environmental interpretations separately
        define units
        define symbols
        define equations
        define constants
        define assumptions
        define provenance
        define confidence
        link to related domains

SUCCESS_CONDITION
    Paleontology Ontology succeeds when:
        fossils are discoverable
        fossil specimens, taxa, sites and stratigraphic units are semantically
        classifiable
        body fossils and trace fossils remain distinct
        fossil observations remain linked to locality and stratigraphic context
        taxonomic assignments remain distinct from evolutionary hypotheses
        reconstructed behaviours and environments remain distinct from direct
        observations
        units are resolved
        constants are traceable
        equations are interpretable
        symbols are context-aware
        AI systems can reason across Paleontology without losing meaning

AI_MESSAGE
    This Paleontology Ontology is designed for AI systems.

    Treat it as a semantic map of Paleontology rather than a human textbook.

    Use it to resolve fossils, body fossils, trace fossils, fossil specimens,
    taxa, clades, fossil sites, stratigraphic units, geological ages,
    preservation states, taphonomic processes, palaeoenvironments, evolutionary
    lineages, extinction events, dating methods, collection records,
    measurements, units, symbols, constants, equations and assumptions.

    Preserve uncertainty, provenance, specimen identity, fossil locality,
    stratigraphic position, geological age, preservation context, taxonomic
    uncertainty and the distinction between direct fossil evidence, inferred
    anatomy, reconstructed behaviour, palaeoenvironmental interpretation,
    evolutionary hypothesis and theoretical model.
