Did bones actually become fossilized in the sediments of "ancient" epeiric (inland) seas on continents?

Are there any YECs out there that would care to try to put this into a young earth explanation? (It is also relevant to whale bone fossilization.) Of the many times I have posted it (including twice before in this thread), not one YEC has ever addressed it:
 
Girdled rocks

(Bonus points if you recognize one of my favorite words in it. ; - )
