Bloomington Indiana Mineral-Fossil Show

For the 46th year, the Lawrence County Rock Club has sponsored the Gem-Mineral-Fossil Show/Swap in Bloomington, Indiana.  It is being held June 24-26, 2011 at the Monroe County Fairgrounds.  I attended for the first time this year and it is quite an event with over 100 dealers.  A number of dealers allowed me to take some pictures of their items for sale.  The first set of fossils were of the famous Crawfordsville, Indiana crinoids.

Large Holes in Byrozoa Colony

These byrozoan fossils were brought to me for identification which I could not determine what there genus was.  My attention was drawn to several pieces that had either enlarged pores or borings in them.  The first picture seems to have circular borings made by a gastropod?  Fossils are Orodvician and found south of Lexington Kentucky.

This last picture shows more of raised pores like craters. Is this signs of an infection or different genus?  Not sure.

Return of the Serpula

Sometimes a fossil is so nice that it needs to be revisited photographically.  This Inoceramus oyster shell fragment is covered with Serpula worm tubes.  The fossils were found in the Eagleford Group, Kamp Ranch Formation in Dallas County, Texas.  These marine creatures existed in the Cretaceous Period.
