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.
