Its fossil Friday, so share a pic of your latest fossil acquisition, or prep. This is my latest prep project, a large Mioplosus from the Green River fm of Wyoming. Its not 100% finished but getting very close. Sadly it had already lost 1/2 to 2/3 of the tail before I found it, it has some damage to the rear dorsal fin, and the original break/exposure was through the head so it will take extra work to remove the glue used for an improvised field repair. I did learn a good lesson and will be bring proper consolidates and glues when I go fishing this year.
