Favosites "Emmonsia" tuberosa

Favosites "Emmonsia" tuberosa found in the Jeffersonville Limestone in Jefferson County, Kentucky (Louisville).  Originally named by Carl Rominger in 1876.  Identified using Silurian and Devonian Corals of the Falls of the Ohio by E.C. Stumm, 1964 (page 68).  Coral existed in the Middle Devonian Period (397 to 385 million years ago consisting of the Givetian and Eifelian Stages).

Described as "Corallum hemispherical to elongate subcylindrical, composed of pentagonal or hexagonal corallites averaging 3 mm in diameter interspersed with smaller trigonal or tetragonal corallites. All corallites with thin walls. Squamulae prominent but relatively short, typically about 1 mm long. Mural pores very large, either parallel or offset biserial. Tabulae typically incomplete, wavy, closely set."

 

 

 

Pennsylvanian Period Plants

Fossil plants from the Pennsylvanian Period (about 318 to 299 million years ago) on display at the Indiana State Museum.

This first fossil is a Neuropteris plicata.  It is some type of seed fern.

Next fossil is an Annularia stellata.

 

This next fossil is an Asterotheca oreopteridia.

 

This last fossil is an Annularia radiata.

 

Devonian Period Plants

Devonian Period (about 416 to 359 million years ago) plants found in the New Albany Shale. These fossils are on display at the Indiana State Museum.


This first two fossil images are of a Callixylon newberryi trunk fossil.  More than likely the tree trunk floated into an area of Indiana and then sank.  Over time the trunk became fossilized.

 

These last two images are of what might be a Calamites in the New Albany Shale.  The Calamites has a relative alive today referred to as Horsetails.
