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.
