    • Specimen collected from the north exposure of the Ausable river, westbound from the northern pit of Hungry Hollow owned and operated by Brampton Brick.

       

      Specimen (prone) complete and intact save for some minor pleural damage on the right side. Specimen retrieved whole with matrix. Preliminary preparation by K. Faucher to remove bulk matrix cover. Second preparation by Malcolm Thornley using a Comco abrasion unit at 7 PSI, with dolomite as the abrasion substance through a 320 mesh screen, 0.15 nozzle and subsequently 0.10 nozzle for more intricate matrix removal.

    A truly beautiful specimen and a rare one as it is complete and unscathed from a classical trilobite location. Thank you for sharing with us.
