Brachiopoda from the Soom Shale Lagerstätte (Upper Ordovician, South Africa)

  • Michael G. Bassett (a1), Leonid E. Popov (a1), Richard J. Aldridge (a2), Sarah E. Gabbott (a2) and Johannes N. Theron (a3)...

Within the Soom Shale Lagerstätte of South Africa (Upper Ordovician, Hirnantian), two brachiopod taxa preserve traces of organic tissue. In Trematis, presumed bands of periostracum are preserved on the flanks of the pedicle notch, and clay mineral casts of the pedicle are preserved in many specimens of Kosoidea. Both these genera are organophosphatic-shelled Linguliformea, together with a third genus identified as Plectoglossa. A fourth brachiopod taxon in the fauna belongs within the calcitic-shelled Rhynchonelliformea (Plectothyrella). Kosoidea cedarbergensis is a new species of discinoidean.
