Skull identity and boundary Establish what evidence makes the subject a skull and which anatomical structures the model includes.
Anatomical recognition
Record the anatomical and material evidence supporting skull identification.
Evidence for skull identification
Capture observed cranial landmarks and material evidence without treating appearance alone as identification.
- Which visible structures support identification as a head skeleton rather than another skeletal element? definition
- What observations or records distinguish biological skull material from a cast, replica or reconstruction? provenance
Included cranial structures
Define the represented skull's anatomical extent and links to neighbouring structures.
Jaw, teeth and associated elements
Make inclusion decisions explicit for jaws, dentition and other associated head structures.
- Does this skull record include the lower jaw and teeth, or link to them as separate things? boundary

Preservation and alteration
Record changes affecting cranial surfaces, form and structural stability.
Located condition observations
Locate deterioration, deformation and repairs while keeping proposed causes distinct from observed features.
- Where are surface loss, deformation, loose teeth, unstable fragments or repaired joins present, and how extensive are they? measurement
- What evidence, if any, supports attributing each alteration to biological processes, events after death or later treatment? provenance
Skull context and permitted intervention Connect the skull's biological and specimen context to decisions about examination, movement and intervention.
Biological and specimen context
Establish the skull's relationship to an organism and the history relevant to its present interpretation.
Organism and specimen history
Record whether the skull remains in an organism or exists as a specimen, including documented preparation and custody.
- Is the skull part of a living organism, part of remains, or a detached specimen, and which linked record establishes that context? boundary
- What documented recovery, preparation, reconstruction or custody history affects interpretation of its anatomy? provenance
Examination and handling decisions
Evaluate proposed actions against anatomical vulnerability, evidence needs and documented authority.
Conditions for skull intervention
Specify the evidence and permissions needed for an action involving the skull or its constituent elements.
- Which cranial regions, detached elements or repairs constrain support, positioning and movement during the proposed examination? action
- What documented authority and specimen-specific restrictions govern the proposed imaging, cleaning, display, reconstruction or sampling? action
- Which anatomical landmarks or future examinations could be compromised by the proposed intervention? action

What it is Filled
This model owns the skull as the biological skeletal structure of a head, whether part of an organism or a detached specimen, including its constituent elements, their anatomical relationships and evidence relevant to its condition and permitted treatment; uncertain boundaries around jaws, teeth and associated structures must be recorded explicitly.
In scope
- Recognition of a skull, partial skull or skull element supported by anatomical evidence
- Cranial elements and their relationships to the braincase, face, jaws and tooth-bearing regions where applicable
- Anatomical completeness, articulation and association of detached elements
- Observable preservation, damage, alteration and structural stability
- Specimen origin, identification confidence and restrictions affecting examination or handling
Out of scope
- The organism's complete anatomy, life history and health record
- Brain, sensory organs and other soft tissues as independently modelled structures
- Postcranial skeleton and whole-body remains management
- Standalone dental models and detailed tooth-level treatment
- Skull-shaped artwork, protective helmets and manufactured replicas as physical artefacts
- Legal determinations, clinical diagnoses and forensic conclusions requiring specialist assessment
Why it exists Filled
Enable an agent to recognise a skull, assess its anatomical completeness and physical state, and determine appropriate examination, handling and use.
Distinguishing features Filled
- Identify anatomical evidence of a head skeleton, such as a braincase region and related openings or facial elements, rather than relying on a skull-like silhouette.
- Distinguish a complete skull from an isolated jaw, tooth or cranial fragment by recording which anatomical regions are actually represented.
- Distinguish skull from postcranial bone through supported anatomical landmarks and relationships; retain an unresolved classification when these are absent.
- Distinguish biological remains from a cast, reconstruction or replica using material observations and documented manufacture or specimen history.
- Distinguish one associated skull from a composite assembly by checking element fit, duplication, preservation differences and provenance.
What robots and AI may and may not do Filled
Must not
- Handle, display or trade human skulls outside the laws and ethics that govern human remains.
- Disturb a skull found in the field that may be evidence of a crime or a burial.
- Treat ancestral remains as curiosities against the wishes of their descendant communities.
- Assign identity, age or cause of death to human remains without qualified examination.
Only with a human decision
- Reporting found human remains to the police or coroner.
- Returning, transferring or destructively sampling a skull in a collection.
May
- Describe a skull's anatomy, species and condition from observation and published references.
- Record a specimen's provenance, catalogue number and handling history.
- Flag a skull of possible human origin to the person responsible for the collection.
Moral aspects Filled
- Human skulls are the remains of people and must be treated with dignity.
- Many museum skulls were taken from colonised or marginalised peoples without consent.
Who is affected
- Descendants and source communities
- The dead themselves
- Collections staff and researchers
Owners Filled
Steward
The museum or collection holding it, or the coroner where remains are found; for living animals, the keeper.

Open questions
- Does the registry intend skull to cover all biological head skeletons, including cartilaginous examples, or a narrower anatomical class?
- Should lower jaws, teeth and other associated cranial structures have a uniform inclusion rule or a documented convention for each taxonomic group?
- What minimum anatomical evidence justifies classifying an isolated fragment under skull rather than a neighbouring skeletal-element model?
- Which reference protocols should govern cranial landmarks, completeness assessments and condition terminology across different organisms?
- Which neighbouring models own human-remains governance, fossil preservation and clinical intervention, and what decision-relevant information must this model retain?
