Page 6: More Brachiopods
Almost everyone found examples in good condition of the articulate brachiopod, Glyptorthis.
Quite a few Dry Dredgers that day were proud finders of the beautiful brachiopod, Hebertella.
The Hebertella can be easily distinguished from the Glyptorthis
by the triangularly shaped hing opening and by one valve (shell) being domed
while the other is a gentle wave shape.
(Note to the astute: The Plaesiomys subquadratus has
this description too, but has a more rectangular outline, among other unique
features.)
When you fossil hunt on these fossil-rich hillsides long enough, you don't
need technical details to tell these brachiopods apart. They begin to look so
different!!!

This Hebertella has an interesting hole in it that may be a boring
from a predator, possibly a platycerid gastropod (snail with an attitude).
