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.

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.

Red Hill Fossil

A while back my friend Herb gave me a piece of matrix from Red Hill roadcut in Clinton County, Pennsylvania, USA. After leaving the sample outside for weeks it began to break apart. In one of the pieces, I found this impression. It looks to me to be some sort of brachiopod with radial lines (costae or plicae) and a light blue layer with maybe muscle scars on it. If it is a brachiopod it is very compressed.

Looking for more information about Red Hill locality (Duncannon Member, Catskill Formation), I consulted the Devonian Times web site. It lists the site as a Late Devonian area (Famennian Stage, 361 million years old). The area was an area that flooded due to a near by river. If this was a river, I am not sure about this fossil since I thought brachiopods were marine creatures.
