Documentation and Reporting

Proper documentation and reporting are critical components of fossil preparation. Keeping detailed records ensures that all steps in the preparation process are traceable, that scientific integrity is maintained, and that future researchers can understand how a specimen was handled. This section outlines best practices for documenting fossil preparation, including maintaining specimen records, capturing photographic evidence, and communicating findings to curators, researchers, and institutions.

9.1 Specimen Records

Comprehensive records are essential for tracking the condition, preparation, and conservation status of each fossil. These records must be kept accurately and consistently to maintain the fossil’s scientific value and legal status.

9.1.1 Initial Condition Reports

• Pre-preparation Assessment: Before any preparation begins, create a detailed report describing the fossil's condition, including visible features, fractures, areas of fragility, and the state of the surrounding matrix. This baseline assessment is essential for tracking changes during preparation.

• Materials Description: Document the material composition of the fossil and its matrix, noting any visible or suspected mineral replacements, organic remains, or fossilization types (e.g., permineralization, carbonization, etc.).

• Provenance Information: Include all available data on the fossil’s provenance, such as where it was discovered, the geological formation, stratigraphic layer, and the context of its collection. If the fossil lacks provenance, note this clearly.

9.1.2 Preparation Logs

• Detailed Log of Preparation Steps: Maintain a log of each stage of the preparation process, including the date, tools and methods used, and the person performing the work. Note any observations made during the process, such as new features discovered, areas of concern, or difficulties encountered.

• Chemicals and Adhesives: Keep records of any chemicals, consolidants, adhesives, or solvents used during the preparation. Document the concentrations, application methods, and reasons for their use.

• Changes in Condition: If the fossil’s condition changes during preparation (e.g., new cracks develop, surfaces degrade), document these changes and any remedial actions taken.

• Detailed notes on Tools marks etc list of tools used

9.1.3 Post-preparation Reports

• Final Condition Report: After preparation is complete, produce a detailed report on the fossil’s condition, highlighting any repaired areas, stabilizations, or changes from its initial state. Include any modifications made for display or research purposes.

• Maintenance and Conservation Needs: Provide recommendations for long-term storage, handling, and maintenance. Note any areas that may require future attention, such as fragile parts that may degrade over time.

• Specimen Cards

• • Each bone element gets its own card which stays with it throughout the preparation process. Information includes the field number with which it was collected, the bone Identification, and the preparator working on it. These can be found in the tool chest.

• Specimen Journals

• • Larger specimens with multiple bones may require more details that can be managed as a journal with generic and repetitive information recorded once.

• Specimen preparation log

• • Individual specimens require a specimen sheet to be filled out.

9.2 Photography and 3D Scanning

Visual documentation is a critical part of fossil preparation, as it provides a clear record of the fossil's condition before, during, and after preparation. Photography and, increasingly, 3D scanning are used to document fossils at various stages.

9.2.1 Pre-preparation Photography

• Overview Shots: Take high-resolution photographs of the fossil from multiple angles before beginning preparation. These images serve as a baseline reference and help document the fossil’s state at the time of discovery.

• Close-up Details: Capture close-up shots of important or fragile features, such as cracks, pathologies, or distinctive textures, to ensure these elements are recorded before any matrix removal.

9.2.2 Progress Photography

• Incremental Documentation: Take regular photos as the fossil preparation progresses, particularly when significant amounts of matrix have been removed or when new features are uncovered. These images provide a step-by-step record of the preparation process and can be helpful for troubleshooting or later review.

• Specialized Techniques: For particularly small or intricate fossils, consider using macro photography to capture fine details. For larger fossils, consider using a photographic scale for size reference in all images.

9.2.3 3D Scanning and Digital Models

• 3D Scanning: Where available, 3D scanning can create highly detailed digital models of fossils before and after preparation. These models are useful for virtual study, sharing with other researchers, and creating physical replicas for display.

• Benefits of Digital Records: 3D models allow researchers to study the fossil in detail without needing to handle the original specimen. They also provide a permanent digital record that can be revisited if the fossil is damaged or altered during handling or storage.

9.3 Reporting to Curators and Researchers

Fossil preparators must communicate effectively with curators, researchers, and institutions, ensuring that all relevant information about the specimen is shared clearly and accurately.

9.3.1 Preparation Summaries for Curators

• Final Preparation Report: Upon completion of the fossil preparation, provide a summary report to the museum or institution’s curator. This report should include details on the fossil’s condition, the preparation techniques used, any repairs or reconstructions made, and recommendations for future care.

• Conservation Needs: Highlight any special conservation needs the fossil may have, such as the need for climate-controlled storage or periodic checks on fragile areas. This information is critical for long-term preservation.

9.3.2 Scientific Reporting for Researchers

• Research-focused Documentation: Provide detailed preparation logs and condition reports to researchers who will be studying the fossil. Ensure that all treatment and modification details are transparent, as these could influence future research outcomes.

• Highlight New Discoveries: If new features or scientifically significant elements are uncovered during preparation (e.g., pathologies, soft-tissue impressions), clearly document and report these to researchers. Such discoveries may impact how the fossil is studied and interpreted.

• Digital Sharing: Where appropriate, share digital resources such as 3D scans or high-resolution photographs with researchers to facilitate study and publication without requiring direct handling of the fossil.

9.3.3 Public Access Reporting

• Display Notes for Exhibits: If the fossil is intended for public display, provide a layman-friendly version of the preparation report. This can be included in exhibit notes, signage, or online resources to help educate the public about the fossil’s preparation process and its scientific importance.

• Interactive and Educational Use: Encourage the use of 3D scans or models in museum exhibits, allowing visitors to explore the fossil virtually without the risk of damaging the original specimen.

9.5 Documenting Challenges and Solutions

Not all fossils are prepared without difficulties, and documenting challenges encountered during the preparation process is valuable for future preparators and researchers.

9.5.1 Noting Problems

• Unexpected Issues: If problems arise during preparation (e.g., unexpected brittleness, over-preparation), document these issues thoroughly. Note the steps taken to address the problem and the outcome.

• Learning Opportunities: These records can serve as important learning tools for future preparators, helping them avoid similar mistakes or develop new techniques for challenging fossils.

9.5.2 Recording Innovations

• Innovative Techniques: If new tools, techniques, or materials are used successfully, document these innovations in detail. This can contribute to the broader knowledge base in fossil preparation and help other preparators dealing with similar challenges.

By thoroughly documenting the preparation process and communicating findings effectively, fossil preparators play a key role in preserving the scientific value of fossils and facilitating future research. Detailed records ensure that fossils remain accessible and informative for generations to come, whether in museums, research labs, or public exhibits.
