Wrangellian Posted August 25, 2012 Share Posted August 25, 2012 (edited) I dont think I have contributed to this topic yet... Not that any of mine will top any of yours for showiness but here goes... These are all from my local Haslam formation, ~84my, and I wish I knew the IDs. The first one or two are what I call 'pancake echinoids' because they're flat and kind of nondescript - I cant even see the ambulacra on them most of the time, though that spotty sort of 'scale' covering them makes detail hard to see (but easy to spot them in the field) - scale weathered off of specimen on right: I'm not sure of the degree to which they are flattened during compaction (at least a bit), but the smaller ones are sometime fatter (on right): I can see the ambulacra on the one on right here, but it need prepping like just about everything else I have!: From other nearby spots, incl. a small heart urchin similar to one I think 'paleopix' Dan posted on p.5, roughly the same size and same Fm/area: Edited August 26, 2012 by Wrangellian Link to comment Share on other sites More sharing options...
Wrangellian Posted August 25, 2012 Share Posted August 25, 2012 (edited) A couple more: some un-ID'd small Regular echs I found years ago, which, as mentioned elsewhere, were found all together on one rock face (bedding plane) and because I was young and clueless we picked them all off one by one instead of digging out the boulder intact (too much work we thought at the time!). Still kicking myself for that. And to think how much more work I've since put into hauling out less-significant fossils than these, than would have been required here. Luckily I saved a few with the spines. Edited August 25, 2012 by Wrangellian Link to comment Share on other sites More sharing options...
Pristichampsus Posted August 28, 2012 Share Posted August 28, 2012 I have many samples of Lovenia forbesi that I picked in in Manum when I was a child, most were weathered out of the rock, so not great detail, still, some good specimens, this is what they look like, wsch mine looked this good. http://www.sciencephoto.com/image/171994/530wm/E4420732-Sea_Urchin_Fossil-SPL.jpg I also have a Madagascan sea bicuit which I bought.

Those should be publication worthy.Don Link to comment Share on other sites More sharing options...
Wrangellian Posted August 28, 2012 Share Posted August 28, 2012 (edited) I know, but who's gonna do that work?? I'm not sure all of the local Irregulars have been sorted out yet either, someone needs to do that work, if possible with the often crushed specimens we get...

RyanNREMTP Posted June 21, 2014 Share Posted June 21, 2014 Here are the three I found in one piece of matrix. I was for certain about one of them. The other two was a wild guess and I am glad I was right. Hemiaster calvini Cretaceous Period Del Rio part of the Grayson Formation Lake Waco Research Area, Waco, Texas.
