One interesting comment that Dr. Briggs made 

towards the end was that the Herefordshire 

Lagerstätte is still unique for soft bodied animals

in carbonate concretions in bentonite. He felt

that there surely must be additional lagerstätte

of this type is just nobody has systematically 

and specifically looked for them. This seems

like a project where fossil hunters, who know of 

carbonate concretions in bentonite bed(s) 

could make a contribution to paleontology.
