Raul-

   Can you give some more information on the bed's geological
context (i.e., is it unique in the formation,or part of a
recognizable cycle? does it differ from the the underlying and
overlying beds in any sedimentological aspects other than
bioclastic concentration? Does it have evidence of a scoured
base, graded bedding, or cross-bedding?  Are the shells and
bones current-aligned?

A good place to start might be numerous papers on storm
sedimentation in this volume:

Cyclic and Event Stratification (Ed. by G. Einsele & A.
Seilacher), pp. 161–174. Springer Verlag, New York.

Another similar volume with the title "Cycles and Events in
Stratigraphy" was published in 1991, and is also worth
checking out.  The papers on the Triassic Musselkalk might be
especially interesting as they discuss both vertebrate and
invertebrate remains in storm beds, I believe.  They are both
available at the UCR library, not far from you.

             Good luck,
                             -Seth
