grendel67 Posted September 13, 2009 Share Posted September 13, 2009 Hi everyone Just have a nother fossil my son have he didn't find it. I bought it at a local auction from a fossil and rock collector. I got it with other fossils in a box and this one didn't have a Id tag with it. To me it looks like a skin print or fossilized skin. I think North Dekota the others in the box was from there. Its about 5 inchs by 3 inch and 1/4 inch thick. Has ridges on one side and not on the other.

Seldom Posted September 13, 2009 Share Posted September 13, 2009 Looks like a eggshell fragment maybe protoceratop. Do you have a picture of the other side?

Auspex Posted September 13, 2009 Share Posted September 13, 2009 I think it's way too big to be an eggshell fragment, and the pattern is wrong in any case for either that or a skin impression. My first thought was that it is coral-like; maybe a calcareous algae or something of the sort?

Algae maybe don't know would still the other side if you can get a picture. Will try to find picture and scan it. Galveston Island 32 miles long 2 miles wide 134 bars 23 liquor stores any questions?

PaleoPutz Posted September 13, 2009 Share Posted September 13, 2009 (edited) That doesn't much look like the shell on any of the eggs that I have. Nor does it look like the skin positives that I have. I don't know what it is, but it is interesting for sure. I believe you should be able to identify egg shell frags from a cross section. You would need access to magnification though. Edited September 13, 2009 by PaleoPutz Link to comment Share on other sites More sharing options...

Seldom Posted September 13, 2009 Share Posted September 13, 2009 HI The second picture is the backside of the piece. Thanks OK not shell!! So coral or algae ?

John K Posted September 14, 2009 Share Posted September 14, 2009 (edited) Coral or algae are possibilities, but my first thought was calcareous sponge. I have a piece from Nora Springs Iowa almost identical. Edited September 14, 2009 by John K Link to comment Share on other sites More sharing options...
lawooten Posted September 14, 2009 Share Posted September 14, 2009 I think JohnK is right. Really cool specimen you found. The best days are spent collecting fossils Link to comment Share on other sites More sharing options...
