Dear Paleocommunity,

I am currently working on an Upper Ordovician crinoid assemblage from Kentucky and have come across some interesting results in XRD of the deposit. We have found a halo of phosphorus around crinoid specimens within a siliciclastic mudstone bed from the Cincinnatian Series.These specimens are beautifully preserved and hence, rapidly buried...

Does anyone have any idea/hypotheses/literature pertaining to phosphorus around preserved specimens? 

I would certainly appreciate any insight or suggestions on this topic!

Much appreciated!
