Any microfossils ?..the matrix is gathered like in five gallon buckets and then screened through many screens and picked out with magnifier type equipment...actually a fun addictive way gather fossils...thanks...jon

Oh what small teeth you have! My son likes to collect shark teeth. I think he can recite all the episodes on Shark Week word for word.

That method of collection kind of makes you wonder who invented it and what where they looking for before they discovered the teeth.
Pretty cool finds
