Nashville Brachiopods

Here are some brachiopods I saw earlier in the week in Nashville, Tennessee. I am guessing they are from either the Nashville or Maysville Groups in the Ordovician Period. This first brachiopod might be a Resserella (aka Dalmanella).

These next brachiopods might be Lepidocyclus (Orthorhynchula).


This might be the bottom half of a Hebertella brachiopod.



Maybe a Lepidocyclus brachiopod.

Again another mixture of Lepidocyclus brachiopods.

Some sort of Resserella or Hebertella brachiopods.


Thanks to the website at www.nashvillefossils.com for help with identification.

Devonian Fossils Found Today

I am tired after collecting at a KYANA field trip this morning. A large group showed up of both KYANA members and a junior group from Evansville. The weather was great and everyone seemed to have a good time. I took a panoramic picture around noon.

This is a trilobite (maybe a Crassiproteus) found in what I guess the North Vernon Formation in Clark County, Indiana. It was not found by me but someone else on the trip. It was enrolled and I don't think it was a molt.

This blastoid was found by the same person who found the trilobite. It is probably an Elaeacrinus verneuili (Römer [aka Roemer], 1851) found in the Jeffersonville Limestone in Clark County, Indiana.

Silurian Period Stromatoporoid

Here is a mounding stromatoporoid or calcareous sponge. It was found in Jefferson County, Kentucky. It appears to be from the Silurian Period and from the Louisville Limestone layer. The picture of the inside of the sponge is neat. It reminds me somewhat of an agate with its layers.
