Tylothyris Brachiopod?


A somewhat crushed fossil but with excellent growth lines shown in this picture.  It appears to be a Tylothyris sp. brachiopod.  The Indiana State Museum web site was used for the identification (see link).

Thanks to Alan at the Falls of the Ohio State Park for providing another identification for this fossil. It could be a Punctospirifer subelliptica (McChesney).

This fossil was found in the Borden Formation of the New Providence Shale Member of Clark County Indiana.  Brachiopod is dated to the Mississippian Period.  Thanks to Kenny for letting me photograph it.

Aulopora on Orthospirifer Brachiopod


One of the easier fossils to prep with sand abrasion cleaning are specimens from the Silver Creek Member, North Vernon Limestone of Clark County, Indiana USA.  I believe it is this layer of limestone that the county's large concrete plant uses to manufacture product.  This fossil is the Orthospirifer brachiopod and it has a nice colony of Aulopora coral growing on it.  The brachiopod and coral lived in the Middle Devonian Period.

Thanks to Kenny for cleaning this one up for me!
