miraspis Posted July 5, 2013 Share Posted July 5, 2013 Hi. The "star" at the bottom is probably rugose coral. The long think above could be some kind of an ichnofossil. Nice find A. Link to comment Share on other sites More sharing options...
TMNH Posted July 5, 2013 Share Posted July 5, 2013 (edited) The shape makes me think of the bryozoan Escharopora but I can't see the surface texture from the picture. If it is a bryozoan it should be covered in tiny pores. http://4.bp.blogspot.com/_kxlrXpSMTVo/S_20WWn74zI/AAAAAAAAAMU/0x1WcPlj88M/s320/IMG_3532.jpg Edited July 11, 2013 by TMNH Link to comment Share on other sites More sharing options...
piranha Posted July 5, 2013 Share Posted July 5, 2013 How about a trilobite spine? It also looks like a possible pygidial spine from Ceraurinella. Link to comment Share on other sites More sharing options...
Indy Posted July 5, 2013 Share Posted July 5, 2013 The shape is comparable to a trilobite spine Bev .. what is the length an width ?? Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
piranha Posted July 5, 2013 Share Posted July 5, 2013 The shape is comparable to a trilobite spine Bev .. what is the length an width ?? Good point to always include a scale in the photo. I'm not sure how that mesh surface correlates size, but it might be way out of bounds for a trilobite! Link to comment Share on other sites More sharing options...
Bev Posted July 5, 2013 Author Share Posted July 5, 2013 It's big. 2.5 inches x .5 inches. I don't think I'm seeing pores, but will try for a closer pic. Thanks guys for looking and taking a guess or two! Bev The more I learn, I realize the less I know.

miraspis Posted July 5, 2013 Share Posted July 5, 2013 The shape is comparable to a trilobite spine Bev .. what is the length an width ?? There is visible pattern on the table so the dimension could be 2-3 cm. I do not think it is trilobite Link to comment Share on other sites More sharing options...
Indy Posted July 5, 2013 Share Posted July 5, 2013 (edited) What ever the mystery represents ... I doubt it's a bryozoan or coral Edited July 5, 2013 by Indy Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
piranha Posted July 5, 2013 Share Posted July 5, 2013 It's big. 2.5 inches x .5 inches... That would be a good size for a complete Ceraurinella! Maybe Caleb recognizes this? Link to comment Share on other sites More sharing options...
piranha Posted July 5, 2013 Share Posted July 5, 2013 Bev, I'm confused, can you please make an exact measurement of the fossil only? Link to comment Share on other sites More sharing options...
Caleb Posted July 5, 2013 Share Posted July 5, 2013 I've seen these every once and a while, but I've always written them off as some type of trace/burrow. Caleb Midwestpaleo.com Link to comment Share on other sites More sharing options...
miraspis Posted July 5, 2013 Share Posted July 5, 2013 ..... written them off as some type of trace/burrow. I agree. Link to comment Share on other sites More sharing options...
Bev Posted July 5, 2013 Author Share Posted July 5, 2013 That was the fossil only. The more I learn, I realize the less I know.
