MarcoSr Posted January 31 Share Posted January 31 I have a jacket with a string of flat shark centra from the Pierre Shale of South Dakota that look just like your specimens.

Marco Sr. Thanks! Do you think i should have jacketed them? Do you know how common these are to find in that formation? Link to comment Share on other sites More sharing options...

Too late now to think about jacketing them. Associated/articulated shark centra are uncommon in the Pierre Shale of South Dakota. Mine were firmly embedded in the formation. I didn't want to dig them out individually at the site. I was afraid I might damage them. I'll probably harden the formation around the centra and the centra themselves (They are quite fragile), and display them as they were found in the formation.

A jacket is mostly for fragile things but it might have helped keep them in order. You can carry them out in aluminum foil to keep them aligned as found but an in-situ photo is good insurance for correct reassembly. Did you keep them all right-side-up and in order?
