JUAN EMMANUEL Posted July 11, 2017 Share Posted July 11, 2017 So excited when this echinoderm I bought online arrived today! It is Camptostroma roddyi specimen from a private property at Lancaster County, Pennsylvania, from the Kinzer Formation. I dont know much about this enigmatic Cambrian echinoderm nor the formation it came from but I cant wait to add this to my small collection of echinoderms. 1 1 Link to comment Share on other sites More sharing options...

Miocene_Mason Posted July 12, 2017 Share Posted July 12, 2017 Good snag, I've hunted once in the kinzer and fossils are not common, so it's definitely a worthy piece for any collection. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

It's questionable, I may have found one, but mineral percipitates make it hard to tell. To give you some perspective, I hunted for three hours and came up with a sponge piece, one possible campostroma, and one worm burrow. It's my understanding that camptostromas are relatively common (more common than the trilobites) but relatively common is rare in my opinion. Yours is definitely real, and almost complete. Here's a picture, it is the porous orange material, it's fragmentary if it is one. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Wrangellian Posted July 12, 2017 Share Posted July 12, 2017 Nice score! I missed that one. Have seen them occasionally, but never at the right price. Link to comment Share on other sites More sharing options...
RJB Posted July 15, 2017 Share Posted July 15, 2017 Wow! Not having a clue to what those are i would have walked right over that or tossed it aside. Again, ya learn something new everyday. Nice find! RB Link to comment Share on other sites More sharing options...
