Productus wortheni Brachiopod Fossil


The Mississippian Period brachiopod fossils Productus wortheni found in the Knobstone Formation of Clark County, Indiana, USA. What is nice is the cast and its negative still in the matrix. Note the small divots in the negative marking where spines were.

Thanks for the image Kenny.

Syringothyrus Brachiopod Lophophore Fossil


Here is a fossil I do not think I have seen before. The Mississippian Period brachiopod Syringothyrus texta found in the Knobstone Formation of Clark County, Indiana, USA. What is special about this is the feeding tube (lophophore) is shown.

Nice find Kenny!
