Uncle Siphuncle Posted October 14, 2010 Share Posted October 14, 2010 Echinoids rock. They are small and therefore store and display easily, and they retain the original calcite surface structure unlike most of the other fossils found in association such as ammonites, gastropods, and certain bivalves, which often occur as steinkerns (internal molds lacking original surface detail). Alas, Ma Nature has made another believer.... Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...

If you are not familiar, there is a good article titled "A Skeleton Made of Calcite Crystals, Sea Urchins and other Echinoderms" by Rupert Hochleitner and Pete Richards in CALCITE extraLapis English edition No. 4. It is worth the read. Now back to cleaning echies Bill Edited October 14, 2010 by calciteguy Link to comment Share on other sites More sharing options...

In particular some material out of faults north of Hutto. Link to comment Share on other sites More sharing options...
MB Posted October 20, 2010 Share Posted October 20, 2010 (edited) Good info on the claw, Alex. Did it change from Palaeopagurus to Pagurus? As far I know, Miss Rathbun named it Pagurus banderensis in 1935 I ignore if later it was called Palaeopagurus sometime, will see it. See you soon , John Edited October 20, 2010 by MB http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...
