Buxtonioides gjeliensis (Ivanov, 1935)


A medium sized productid with strong shell curvature and
cross-hatched pattern of concentric and radial ribbing. This gives a
beaded appearance to the ribs and spines grew from the tops of the
beads over much of the ventral valve (Ivanov, 1935).

Viewer comments:

This brachiopod has a cross-hatched pattern of ornamentation on
the early-formed part of the shell, produced by close-spaced small
concentric ribs crossing narrow radial ribs, a pattern that is common
in dictyoclostid brachiopods. Swollen spine bases on the tops of ribs
increase the irregularily of the surface. This genus is part of the
family Productidae, a family of brachiopods with spines limited
(mostly) to the ventral valve.
