PETITION-Armored Mud Balls
Return to Historical Commission
Gill is one of the few locations in the world where armored mud balls are found. Embedded in sandstone, they date from the Jurassic Period, Mesozoic Era. Details of their formation may be found in GHC’s Riverside book on page 7.
Given their rarity, GHC is supporting the recognition of the armored mud balls as an official Massachusetts State Geological Symbol. If you would like to sign a supporting petition to recognize the mud balls, or want further information click here which is part of a lobbying effort organized by Richard Little, GCC Professor Emeritus.
