Fiwi Posted November 11, 2009 Share Posted November 11, 2009 I'm usually out looking for indian artifacts, but lately I've come across a couple of fossils. Can you ID the first two for me and what, if anything is the third one? TIA! Link to comment Share on other sites More sharing options...
Auspex Posted November 11, 2009 Share Posted November 11, 2009 The first one is, I think, contains the cross-section of a crinoid ("sea lilly) stem. The second one might be Bryozoan ("moss-animal), but the pic is a little fuzzy. My take on the third is that it is a mineral formation.

Bear Posted November 11, 2009 Share Posted November 11, 2009 Agreed. Further the last one appears to be a pocket of worn drusy quartz crystals in a quartz mineral group parent stone like jasper, agate or quartzite. Link to comment Share on other sites More sharing options...

dutchhunter Posted November 12, 2009 Share Posted November 12, 2009 The first is what I believe is a cross section of a sponge. Link to comment Share on other sites More sharing options...
Ron E. Posted November 12, 2009 Share Posted November 12, 2009 The first is what I believe is a cross section of a sponge. I vote horn coral. Link to comment Share on other sites More sharing options...
Plantguy Posted November 14, 2009 Share Posted November 14, 2009 I vote horn coral. Hey Gang, I put in a 2nd vote for the horn coral ID for the 1st fossil. Moore's Invertebrates fossils has a number of figures showing solitary rugose cross sections (different genera) from different ages similar to this cross section. Stereocorypha sp.(Pennsylvanian),Metriophyllum sp. (Devonian), Zaphrentoides sp. (Mississippian) to name 3. Not sure if any are the actual one but I present them as examples of the flower-like pattern shown. Regards, Chris Here's also a cool link from the Kentucky Geological Survey on identifying fossils by shape. Will help explain the process of elimination we all go thru sometimes. Not definitive this time but explains different choices to eliminate. http://www.uky.edu/KGS/fossils/fossilid.htm Link to comment Share on other sites More sharing options...
