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.

I recently inherited this fossil fish from my stepdad, who traded a pair of moccasins for it at a rock show in the 80s. The seller claimed it was from the Green River formation, but given the matrix, color, and three dimensionality I highly doubt that. A quick Google search leads me to believe it’s probably from the Santana formation in Brazil and possibly a Rhacolepis buccalis? I’m a geology student but living in invertebrate country I can’t say I know a lot about fish identification I’m happy to add more pictures as needed or provide what little info I can. Thanks in advance!

Brazil has some of the most incredible fossils in the world, and I feel not enough appreciation is given, especially to the fish of the Crato Formation! I have briefly been obsessed with the fossils from Brazil as I purchased my first and only fish from there, a small Dastilbe! With the import ban these fish are becoming rarer and rarer I would love to see what some of the older people got while the market was still open! I would also be interested in seeing the isolated teeth from the Spinosaurid from Crato!

Hello all Today this fish came in my mailbox together with a specimen of Rhacolepis buccalis. This fish does not seem to be of the same species, but the skull, fins and tail are in bad shape or even absent. Most of the 'skin' is gone, uncovering some of the bones beneath. I know this will make it hard to ID, but maybe one of the fish experts can help me out. It's from the Cretaceous Santana formation of Brazil and it's about 21 cm long. Thanks in advance.

Abundant in Santa do Cariri. Exceptionally large ones occur rarely in Jardim. 5db5f6529e3cd_Tharrhiasararipisreconstr.JPG.50423fc298c70e4279ed389ed0986837.jfif

Scales and form look similar to Rhacolepis Buccalis, but puzzled by the rather elongated slender body Thanks

Here are two fossilized insect specimens from the Santana Formation in Brazil during the early Cretaceous period. Do let me know in your opinion, what type of insects do you think they were and if possible, their genera or species names will be much appreciated. Thanks.
