  1. Hmmm, Its a lophotrochozoan fr sure, but is it a Pecten-like bivalve or an Atrypa-like brachiopod? I'll take a wild guess at Aviculopecten a scallop-like bivalve.

  2. Brachiopoda, Order Rhynchonellida?

    Past that, well, it looks a lot like a picture of Soaresirhynchia, except for the color, and that might be a mineralization thing... so I'll go with that.

  4. I'm going to say a Pecten but I can't be more specific without more info.

  5. I must admit, it didn't occur to me that it might be mistaken for a brachiopod until after I'd put it up. I'm going to give two points to Neil, who got it right but didn't say why, and one point to Paleo. The main difference I can see to Dunbarella is that Daonella doesn't have the dorsal 'wing(s)' that Dunbarella (and Aviculopecten) have, but that might not be obvious in the photo if you didn't already know what it was.

  6. This is a Dunbarella. The line in the patten are specific. Also the shape contributes a lot to the species.
