  • 16. Actinocrinites gibsoni
  • 17. Macrocrinus mundulus
  • 18. Undetermined
  • 19. Undetermined
  • 20. Camptocrinus myelodactylus

To me the keynote specimens are the wonderful Actinocrinites gibsoni with attached stem (#16), the uncommon Ophiuroid starfish Onychaster flexilis (#1), and the very rare Aulocrinus bellus (#10). Seeing a specimen like this makes it easy to understand how highly regarded the Crawfordsville site is as a location for the treasure trove of crinoids to be found there. This specimen is undoubtedly destined to be the cornerstone of any private collection, and is suitable for museum display. I will let the photographs speak for themselves. Customers outside the US should note that the shipped weight would be roughly 6 KG.
