    description: "A biological specimen or natural history object held in a heritage\
      \ collection.\n\nModels organisms, parts of organisms, or biological products\
      \ preserved for\nscientific study, education, or display.\n\n**CIDOC-CRM Alignment**:\n\
      \nE20_Biological_Object - \"Physical objects that have been produced by \nbiological\
      \ processes and include organisms, parts of organisms, and \nbiological products.\"\
      \n\n**Key Distinction from ExhibitedObject**:\n\n| Concept | Class | Example\
      \ |\n|---------|-------|---------|\n| General museum object | ExhibitedObject\
      \ | \"Girl with a Pearl Earring\" |\n| **Biological specimen** | **BiologicalObject**\
      \ | **Dodo skeleton** |\n| Archaeological find | ExhibitedObject | Roman pottery\
      \ |\n\n**When to Use BiologicalObject**:\n\nUse for specimens that are primarily\
      \ biological in nature:\n- Taxidermy mounts (mammals, birds, fish)\n- Study\
      \ skins and skeletal material\n- Herbarium specimens (pressed plants)\n- Wet\
      \ specimens (fluid-preserved animals)\n- Fossils of organisms\n- Entomological\
      \ collections (pinned insects)\n- Paleontological specimens\n- Living collection\
      \ records (botanical gardens, zoos)\n\n**Darwin Core Integration**:\n\nBiologicalObject\
      \ aligns with Darwin Core (TDWG) occurrence/specimen standards:\n- `taxon_name`\
      \ → dwc:scientificName\n- `collection_date` → dwc:eventDate\n- `collector` →\
      \ dwc:recordedBy\n- `preservation_method` → dwc:preparations\n- `gbif_id` →\
