Frozen treasures

Found two nice stingray mouthplates almost two years ago along the Potomac.  I went collecting by rental-boat on both the MD and VA side of the river.  Found a few teeth here and there, and then stumbled upon two ray plates still in clumps of matrix.  I didn't have anything to wrap them in so I stripped down to my t-shirt, took it off, wrapped each mouthplate, then got dressed.  It was freezing cold and my skin was numb from the wind and winter drizzle. 

I forgot about these ray plates and had them stored until recently when I re-discovered them while looking for something else.  One came out nice and clean, while the other I prepped to stay on the matrix since it is fragile.  I might stabilize it with a 50-50 mixture of elmers-water, then try to remove it from the matrix to see the root structure.

It's really great to find them still complete like this!
