mommabetts Posted September 15, 2009 Share Posted September 15, 2009 (edited) I can't tell which one for sure but it is in the Neithea Family. I want to say it is texana. Edited September 15, 2009 by mommabetts Link to comment Share on other sites More sharing options...
JohnJ Posted September 15, 2009 Share Posted September 15, 2009 I can't tell which one for sure but it is in the Neithea Family. I want to say it is texana. No brachiopod, Daniel. As mommabetts noted you have a Neithea texana...very nice. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Shamalama Posted September 15, 2009 Share Posted September 15, 2009 Those Neithea are confusing to me, they really look like Brachiopods unless you get down to fine details. The Gryphea and Pyncodonte oysters are the same way for me. Pelecypods are supposed to have equal halves down the hinge line! grrrr Are there any other orders like the Ostreoida and Pectinoida that are inequivalve? -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

jkfoam Posted September 15, 2009 Share Posted September 15, 2009 Shamalama, Lets see, the Order Isodonta are inequivalve also the Order Pachyodonta which includes the Suborder Rudistacea. The Rudist clams seem to have the most inequal valves. In the Rudist clams the minor valve is not hinged to the Major valve and does not "swing" open. The minor valve opens by being raised straight up like taking a hat off your head. JKFoam The Eocene is my favorite Link to comment Share on other sites More sharing options...
Shamalama Posted September 15, 2009 Share Posted September 15, 2009 JKFoam, makes me wonder if they shouldn't all be grouped in a Superorder or combined in a single order. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.
