One rock, two fossils. This rock has two mold fossils of brachiopods. The rock measures ~74 mm (2.9 in) long, ~63 mm (2.4 in) wide) and ~11.8 mm (.46 in) thick). Fossil #1 measures ~15.6 mm (. 61 in) tall and ~19 mm (.75 in) wide. Fossil #2 measures ~11 mm (.44 in) long and ~2.8 mm (.11 in) wide. These fossils date to the Devonian Period (416-359.2 million years ago). I believe the rock is limestone.
Rocky creek bed. Euclid Creek. Euclid, Ohio.
This rock was found in the summer of 1986 at the Euclid Creek Reservation, Welsh Woods Picnic area. I was skipping stones and picked this up to skip it but when I flipped it over I found this excellent brachipod fossil. It was not until 2012 that I realized there was a second fossil on the rock which appears to be another small brachiopod. The close up pictures were taken with a Digital Blue QX5 USB Microscope at 10x power.
