Mediospirifer Devonian Brachiopod

Here is a brachiopod fragment from North Vernon formation in Clark County, Indiana. It might be a Mediospirifer from the Devonian period. Normally, one would not post an image of fragment but only whole brachiopods. When turned over this one reveals part of its lophophore that has been broken off. This tube series makes it pretty neat since you get a view of the fossilized inside of the lophophore.

A little dot is visible inside the coil of the lophophore.

Aulaphyllum Horn Coral

Here are some images of fossils that are probably Aulaphyllum horn corals from the Devonian period. It was found in north east Jefferson County, Kentucky.

Cystiphyllum Horn Coral

Here is a image of a Cystiphyllum horn coral found in north east Jefferson County, Kentucky. It is from the Middle Devonian period in the Jeffersonville or Beechwood Limestones. You can see evidence of the cysts or sacks on this coral.  This coral was later renamed Cystiphylloides I believe for the Devonian Period corals and Cystiphyllum was used for Silurian Period corals.
