From the album: Lime Creek Devonian Rockford Iowa
Cyrtospirifer whitneyi - the most variable in shapes of all the brachiopod species at Lime Creek Formation. No one knows why its so variable as the only thing close to it is oysters, jewelboxes and such but they lives on hard substrates not on stalks on muddy bottom like spirifer brachiopods. One half may be nearly flat, or greatly inflated. Wings can be so extreme that it look more rectangular or may be absent. Sulcus may be greatly reduced in juvenile forms. Ribs can vary from fine to coarse. -
Gravel find so a bit worn. First of these seen in rocks from this pit. Could it be cyrtospirifer?

I've always wanted one of these and it's just arrived! I spotted it on the usual auction site where it was being sold by an antique seller as a possible fish in slate . It is true slate but is a legendary Delabole Butterfly, a metamorphosed Cyrtospirifer extensus, almost certainly from the Delabole slate quarry in Cornwall, UK. Although quite famous and widely referred to, there's not that much solid information. They appear to have been sold to tourists, largely in the 19th century and this split specimen seems typical. I think they're quite rare though - most photographed specime
