Other corals from Iowa

Here are some corals that my friend Nathan gave me from the Cedar Valley formation of Iowa (Devonian, Givetian stage).

A couple of Favosites: Specimen #1


Specimen #2

Side by side

A rugose coral of unknown species




Some more rugose corals

And then there is this brachiopod specimen with small coral growth remnants attached to the shell. I don't know what species they were but I do love shells with epibonts.
Thanks to Nathan for the specimens.
