FOSSILS OF ARKANSAS

Chris Brown's fossils

This is a great fossil that Chris Brown found on his property in north central Arkansas, Marion County.

This is an internal mold of a crinoid calyx in the chert of the Mississippian Burlington Fm. Note that a lot of the internal structure is preserved.

Leslie, Arkansas [July 4, 2007]

These fossils from the Leslie area, are all of the Mississippian age. Corals, bryozoa, brachiopods, crinoids, bivalves, gastropods, cephalopods, and plant fossils are common in some intervals throughout the sequence. The Mississippian rocks are limestone, shale, chert, and some sandstone.

The fossil (one that looks like a cork screw) below, is a bryozoan Archimedes.

Small horn coral.

Here are good examples of intact horn coral that Lance found in Texas.

Crinoid stems in the host rock (right lower) and I now believe the larger fossils are actually Nautiloids, which are a form of the Cephalopods.

The property that I was hunting on is pictured below. It was beautiful and peaceful there. Thanks to Thad and his family for letting me hunt on their land.

More nautiloids and small crinoids stems in the next pictures.

Shells in a much harder matrix, found at site 2. (below)

Large limestone rocks on their property were fossil rich. (below)

Possum Grape, AR

This maybe a Linthia alabamensis Clark echinoid. It is the oral view.

My First Trilobite! This one is a member of the Phillipsiidae family, superfamily Proetoindea, order Proetida.

Surprise friend

The crinoid stems were really well worn except this one. Both sides pictured
