Hawkeye Posted July 7, 2009 Share Posted July 7, 2009 I'm still kicking myself for not taking pictures of these guys in situ, but when you get in that hunting zone it's very hard to remember the camera. That, and it was about 98 degrees out. This was a site pointed out to us by NALhunter that we stopped at on the way to Point-A Dam. The echinoids were all over the place! I thought I was getting a few different species but it turns out I just got one species in various states of decomposition. Here is the site again Here are a couple of matrix shots before I worked the echinoids out After quite a bit of air scribing and a little bit of vinegar, this is what I got These oysters were pretty abundant as well, and yes, the small one really is green! I'm hoping somebody can help me figre out what this is. It's about the size of a half dollar and seems to have a very thin shell Top, bottom, front, back Thanks again Del!!!!!

Guest N.AL.hunter Posted July 7, 2009 Share Posted July 7, 2009 You actually ended up with some good specimens from that site. Way to go. can't help with the Id of the thing. Link to comment Share on other sites More sharing options...
LanceH Posted July 7, 2009 Share Posted July 7, 2009 Can you take a picture of the bottom of one? That would be helpful with the ID. So far I'm thinking a Hardouinia echinoid, but don't know exact species, maybe bassleri??. I'm just going by a similar echinoid online. This would be an upper Cretaceous echinoid if the text is correct. Link to comment Share on other sites More sharing options...
Coco Posted July 7, 2009 Share Posted July 7, 2009 Nice finds. Is somebody knows the name of these sea urchins ?

bj aurora Posted July 7, 2009 Share Posted July 7, 2009 Nice echinoids! I can't really help with the mystery fossil except a wild guess - I am not familiar with the fauna of that area, but it reminds me of a bivalve of some sort... Link to comment Share on other sites More sharing options...
Roz Posted July 8, 2009 Share Posted July 8, 2009 Those echs preserved in excellent shape. Unusual to see the plates so clear like that. Great finds! Welcome to the forum! Link to comment Share on other sites More sharing options...
jkfoam Posted July 8, 2009 Share Posted July 8, 2009 I believe Lance is correct. The echinoids are Hardouinia bassleri. As for the other fossil shown, it looks like an oyster that was growing on top of another clam. That is why it shows the ribbed appearance. JKFoam The Eocene is my favorite Link to comment Share on other sites More sharing options...

JohnJ Posted July 8, 2009 Share Posted July 8, 2009 Very good echies! I agree with JKFoam; some kind of oyster that grew up on another clam. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

jpbowden Posted July 13, 2009 Share Posted July 13, 2009 The last four appear to be an Exogyra laeviuscula, but very compacted. Contrary to the nice ones seen in collections, a lot of then look like this and are never ID'ed. I have so many oysters that even have formed echinods, looks like an oyster with a tattoo.

Shamalama Posted July 14, 2009 Share Posted July 14, 2009 Very nice Ecinoids! -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

jpbowden Posted July 14, 2009 Share Posted July 14, 2009 If you will look at the bottom four photo's and at the first one, on the right hand side under the attachment scar you will see what looks like a curl. This is common with Exogyra. And to the right of the first photo, is the bottom of this animal, though filled in you can still see it's outline. See how the lower right hand side has an area that seems to roll out in layer, this is found on smaller Exogyra laeviuscula. Now on photo four, bottom right, you will see how thick it is, Exogyra laeviuscula is a very humpy oyster and has a thick shell across the back, this would help maintain this thickness even with such a massive scar.
