Trading Places in a Devonian Sea

 

My cousin Kenny sent me some pictures of some fossils he screened from micro material I brought back from Alpena Michigan USA. What I found interesting was two specimens show the interactions between bryozoan and coral fossils. One specimen shows a coral growing on a bryozoan and another shows the reverse. First picture shows an Aulopora (Goldfuss, 1829) coral growing on what appears to be a Fistulipora (McCoy, 1849) bryozoan. The next image shows an Aulocystis ramosa with a matting Fistulipora bryozoan growing on top of it.

The next image shows the same type of coral fossil with a matting bryozoan. Field of view (FOV) in these images is about 12-15 mm.

It was found in the Potter Farm Formation and dates to Middle Devonian Period (Erian Age). Thanks to Kenny for image and screen material to find fossil.

Strophondonta crassa Brachiopod Fossil

Screening through a lot of micro material brought back from Alpena Michigan USA. This brachiopod fossil appears to be a Strophondonta crassa (Imbrie, 1959). It was found in the Potter Farm Formation and dates to Middle Devonian Period (Erian Age). The length is about 13 mm. The fossil shows signs of having a worm tube or snail attached to it. Also maybe an Aulopora coral in the bottom left part of the shell.

Thanks to Kenny for image and screen material to find fossil.
