Hipockets 21 Report post Posted November 22, 2018 My son has couple of pieces of aldebarania ( starfish) found in Pee Dee formation from Rocky Point NC, that have great preservation. On one piece there is an object that appears to be a sponge maybe ? Any ideas? Thanks. Share this post Link to post Share on other sites
