Dictyonella reticulata Brachiopod

Dictyonella reticulata brachiopod found in the Waldron Shale of Clark County, Indiana.  Creature lived in the Middle Silurian Period (412-425 million years ago). This species is my first find and while not perfect it has taken me some time and effort to find one!  Hopefully more of the matrix will come off once it is sandblasted.

UPDATE:  Tony at the Fossils and Other Living Things blog has posted a very informative entry about this species of brachiopod. It was once known by the genus Eichwaldia and in 1994 renamed Eodictyonella by Wright in Journal of Paleontology July 1994. He also reviews what caused the pattern on the brachiopod shell. Dave at Views of the Mahantango also reviewed the Dictyonella found in New York with this posting.

Next image shows its unique diamond shape patterned surface under the microscope.  Very cool!
