I have been prepping out bivalves from the Edmunds Fm. Below are the ones I have prepped and collected so far. Most of them were consolidated with Paraloid. They are all rather incomplete, but still show the characteristics of their respective species.
A right valve Eurymyella shaleri. The external mold was practically destroyed, but the cast survived mildly well. It is 5cm long.
And a Nuculites corrugatus, with the external mold having survived better this time. The cast, though, shows more detail. Cast is on top, it is 4 cm long; external mold on bottom, it is 5 cm long.
