Coral Fossil


There are two very distinct fossils on this rock. The first is a relatively large specimen of what is most likely coral. The second is a brachipod of some type (see spotting The rock measures ~41 mm (1.6 in) long, ~16 mm (.62 in) wide and ~17.5 mm (.69 in) thick. The fossil measures ~22 mm (.88 in) wide and ~11 mm (.44 in) tall. This fossil dates to the Devonian Period (416-359.2 million years ago).

I kicked this rock aside with my foot and noticed the brachiopod fossil staring right up me. The close up pictures were taken with a Digital Blue QX5 USB Microscope at 10x power.

I believe the limestone fossils in Florida are much younger than this, but I found something very similar here. What do you think?
