I was wondering if there was a common term used for the fossils that remind me of a glob of construction adhesive. Sometimes binding fragments together sometimes just an unrecognized mass sandwiched between pieces of limestone.

I don't now if there's a special word. 

We can talk about a mass mortality plate or bed when lots of organisms were killed in a catastrophic event and buried together, or we can have a crinoidal limestone, where much of the rock is made up from crinoid remains or an oyster bed containing largely fossil oysters etc.

Maybe Calcium Carbonate...

The common name for a rock with a lot of animal pieces is typically a "hash plate", but they are also referred to as death or mortality plates.

Or maybe coquina if it’s not quite limestone.
