[NHCOLL-L:4617] Inquiry about a paleo fish

[Bryant, James]

A patron brought in the fossil depicted in the attached image. The
specimen is preserved in one half of a limey concretion that is just
over 9 inches long. There are numerous, small calcite crystals thoughout
the concretion and in cavities of the fossil. The remains appear to be
of a ray-finned fish with cycloid scales, but the patron has no
information on its source (it was simply "found in the garage"). In my
limited experience, the preservation of some fish fossils is quite
distinctive, so I wondered if anyone would want to venture a guess as to
the origin of this fossil?
