Claiborne Amber (Cockfield Fm., 41.3-38 Ma)
1.4g translucent specimen measuring (mm) 16x15x10; one side presents an unbroken exterior, with slight remnants of sand, clay, and lignitic matrix. This material was recovered from the Malvern Clay Pits, east of Malvern, Arkansas. FTIR spectrum comparison of Claiborne amber to modern Shorea sp. resin points to the Dipterocarpaceae as a probable source for this middle Eocene-aged amber.
