Attached are photos of a fossil fish nodule collected in northeastern Brazil, South America in the early 1970's. It is about 26 inches (66 cm) long and about 6 inches (15 cm) wide. Uncertain as to age, but based on preservation, I assume it was collected from the Santana Group (? Crato Fm.), Lower Cretaceous. I'm guessing it belongs to the Amidae family, but I have no expertize in these fish. I'd appreciate any help as to identification. Thank you.

Hello everyone I was browsing on a well known online auction site a few nights ago and spotted this fish fossil. Thinking it looked interesting with a current low bid I put in a cheeky last second bid and got it. It was listed as 'prehistoric fish fossil, Sandstone, two halves' so that's not a lot of help in identification. Looking at the preservation before and after purchase I'm thinking it is from Brazil? Potentially the santana group? Preservation isn't preticualy great, especially around the head and it looks to have partially fell apart because of this I'm not sure of the identification. I'm thinking Rhacolepis? Mind you I could be completly barking up the wrong tree! All comments welcome.
