Hipockets Posted November 22, 2018 Share 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. 3 Link to comment Share on other sites More sharing options...

Sort of both. I'm pretty sure they are internal structures of this star. 2 Link to comment Share on other sites More sharing options...
