Devonian Fossils |

 |
|
The Devonian Period, The Age of Fishes, lasted for 60 million years ending 359 million years ago. Fish poliferated and sharks appears. The first four-limbed animals made it onto land. I've collected Devonian fossils from several deposits. |
These are from quarry southwest of Albany. The brachiopods are unusually large, 2 or more inches for each specimen. In most cases, the shell material has dissolved leaving casts.

This brachiopod is from another site near Albany. It's about an inch across. |

 Leptaena sp. |

I thought this was a tabulate coral but recent information leads me to believe it may be a receptaculite, a calcareous algae. More research needed. The second image is many branching and lacey bryozoan. |
