Devonian Fish Bone Fossils

 

These pictures are of a somewhat unique and rare fossil found in the Louisville Kentucky USA area. The almost fossil bare New Albany Shale sometimes reveals a blue material that are the fish bone remains from the late Devonian Period. These fossils were found in the Blocher Formation of Clark County, Indiana, USA. The main pieces is about 2 cm in length. 

The fossils once belonged to Barbara Conkin(1928-2019) who taught geology at Jefferson Community College. Thanks to Kenny for taking these pictures.

Turrisasps elektor Fossil

Here are pictures of a primitive fish fossil called Turrisasps elektor (Daeschler, Furmes & Mullison, 2003). Note fingernails in picture on size of these fossils. It existed in the  Upper Devonian Period and was found in the Catskill Formation Duncannon Member of Red Hill Pennsylvania USA.

Thanks to Kenny for the images. 

 

Ageleodus pectinatus Fossil Teeth

Here is a picture of two sets of fossil teeth from a primitive shark called Ageleodus pectinatus (Agassiz, 1838). Note fingernails in picture of an idea of how small these fossils are. It existed in the  Upper Devonian Period and was found in the Catskill Formation Duncannon Member of Red Hill Pennsylvania USA.

Thanks to Kenny for the image. 

Hyneria lindae Fish Tail Fossil

On a recent trip to Pennsylvania, my cousin was able to see a collection of fossils. This picture is of one of them. The creature was an early lobe-finned fish like an Eusthenopteron (Whiteaves, 1881) related to tetrapods. This particular fossil has been identified as a Hyneria lindae (Thomson, 1968). It existed in the  Upper Devonian Period and was found in the Catskill Formation Duncannon Member of Red Hill Pennsylvania USA.

Thanks to Kenny for the image. 

Chonostegites clappi Coral Fossil

 

Here are some pictures of what appears to be a Chonostegites clappi (Edwards & Haime, 1851) coral fossil. It was found in the Jeffersonville Limestone of Clark County, Indiana USA. The fossil dates to the Middle Devonian Period.

Species appears to have been named for Dr. Asahel Clapp (1792-1862) one of the first medical doctors in New Albany, Indiana and a frequent collector of fossils from the Falls of the Ohio area. The holotype for this species is supposed to reside in the École des Mines of Paris France.

 Thanks to Kenny for the images. 

 

Ptiograptus percorrugatus Graptolite Fossil

 

These pictures are of what appears to be Ptiograptus percorrugatus (Ruedemann, 1908) graptolite fossil. It was found in the Jeffersonville Limestone of Jefferson County Kentucky, USA. It existed in the Devonian Period.

This fossil was first posted on this blog in 2011 where I mis-identified which layer it was in thus the wrong time period. Recently, I located the box this fossil was stored in and my cousin Kenny re-imaged it. New details emerged when he started taking negative images of the fossil revealing small pores in it. See images below.

 

 

 

Hippocardia cuneus Fossil

This picture is of a Hippocardia cuneus (Conrad, 1840) rostroconch fossil. It existed during the Devonian period. The fossil was found in Louisville, Kentucky USA. Fossil was on display at the Natural History Museum Vienna (Naturhistorisches Museum Wien) on August 2024.

Note: Their label does not appear to be correct. It listed the fossil as "Hoareicardia cunea" being a "schnabelschaler" of the "Karbon". If it was found in Louisville then it was not in the Carboniferous Period.

Alpena Michigan Microfossils

 

My cousin screened through a lot of micro material I brought back from Alpena Michigan USA in October 2021. It was found in the Potter Farm Formation and dates to Middle Devonian Period (Erian Age). 

The brachiopod fossil in boxes 110 & 117, 76-77, and another in 109 appear to be a Strophondonta crassa (Imbrie, 1959).

Rectangles 107, 108, and 115 appear to be Aulopora coral fossils with some that had grown on a branching bryozoan.

Cornulites appear to be in boxes 60 and 61.

A blastoid in cells 62, 63 & 66 could be Heteroschisma subtruncatum.

Cell 22 is a fish tooth fossil.

Fossil in rectangle 69 is some sort of bone fossil.

Thanks to Kenny for image and preparing all those fossils. Very nice work!

Aulopora Coral Fossil

This picture is of an Aulopora (Goldfuss, 1829) horn coral fossil. It existed during the Devonian period. The fossil was found in Caledonia, New York, USA. Fossil was on display at the Natural History Museum Vienna (Naturhistorisches Museum Wien) on August 2024.
