Thrift store 10" fish sederite nodule fossil find need help with ID

[Lost&Found]

This is a cross post from the Garage Sale thread. I need help in IDing it.

Found this specimen at a thrift store yesterday. At first I thought it was a child's DIY make a fossil but after seeing the mineralization it never left my hands. I would appreciate help in IDing it.

The nodule measures 11" x 5" and is quite heavy. The fish is 10" x 3".
I just noticed hand writing on the borders (haven't had time to decipher it yet) and will soon post better pictures then the ones posted now. Any help would be appreciated.

Might be a fish from the Cretaceous Santana Formation of Eastern Brazil.
