Collector cautions

Provenance questions

  1. What is the most precise locality that can be responsibly shared?
  2. What formation, member, quarry, or horizon is claimed?
  3. Who collected it, when, and on what type of land?
  4. Was export documentation required, and does paperwork accompany the specimen?
  5. What preparation, stabilization, repair, or assembly occurred after collection?

Why locality affects identification

Fossil groups have geographic and stratigraphic ranges. Matrix, preservation style, associated fauna, and preparation traditions can support or contradict a locality claim. A famous locality name should never substitute for documentation.

Build a comparison set

Use listings to compare morphology, matrix, preparation, locality claims, dimensions, repairs, and seller disclosure. Similar appearance alone does not establish identity or legality.
