Looks too good to be true. I vote fake. Did you find this or buy it. Looks like somebody did some prep work on it.

If you found it, where was it found. If you bought it, what info came with it?

Info: Craig Hyatt, retired software/electrical engineer

Experience: Beginner, fossil hunting less than a year

Location: Eagle Pass, TX USA on the border with Mexico, hot dry desert

Formation: Escondido, Marine, Upper Cretaceous

Materials: Sandstone, Mudstone, Shale, Chert, Chalk

Typical: Thalassinoides, Sphenodiscus, Exogyra, Inoceramus

Any further details you provide could help with an identification :)

This is a real fossil fish concretion (slightly enhanced).

It comes from the Araripe Basin, Santana Formation in Brazil - age is early Cretaceous.

The enhancement is where they gently "carved" the outline around the fins/body of the fish.

I'm not sure on the species of this - could be a Brannerion sp., or Tharrias araripe.

You could look through this PDF for further ideas.

It's Fakeichthys malefactus.

Easy on the 'trigger', guys; we're tryin' to catch some fish, here. :D

Years of google..... :P

EDIT: Actually, the more I look at that tail, (the positions of the caudal fin rays,and raylets ) the more I'm thinking it may be Araripelepidotes temnurus.

Not to be contrary, but I *still* think it looks fake. First, there's the perfect prep work, then the perfect color and detail, and lastly, how do you split a fish in half and get fins and scales on both halves? Where's the skeleton?

You are only seeing one side of the fish, a mold and cast.

The "middle" is destroyed during the formation of the fossil, sometimes leaving the imprints on both sides.

Madagascar fish nodules are similar.

My mom gave it to me cause I thought it was interesting . always wanted another fish, and can't forget to feed this one. Its about 8.5 inches long . rock looks geoed..ish. But im just as good one guessing at rocks as I am fossiles of fish . so next step is to figure out what fish it is ? And if its real.

Step 1. Ignore everything I said. It's a real fossil fish. :-)

Craig,

Tony is correct on this one - Mold and Cast

post-2806-0-06974100-1467343010_thumb.jp]

It is real, and possibly Araripelepidotes temnurus.

These nodules require little in the way of prep, usually.

They outline some of these to make them look more complete.

The fins are not usually well preserved, or not complete, so they make them look complete.

i agree with Tim.

the prep is usually rough with these fish from Brazil, and they will often "enhance" the fins (i think it's a off putting look). But to each their own.

nice hand me down piece.

So do I use it as a conversation piece and make my friends guess what kind of fish and fossile it is... Seeing as how I will now sound intelligent lol. Or is it a unique special little imortilized impression fish ?

How do o know if it fake

Most fish fakes are carved and painted to look like a fish. They have no fine details. If You see one it should be obvious.

So do I use it as a conversation piece and make my friends guess what kind of fish and fossile it is... Seeing as how I will now sound intelligent lol. Or is it a unique special little imortilized impression fish ?

Enjoy it as a relic of the past, and amaze Your friends at the same time.

The Brazilian government does not allow the export of these fossils any more, but they were plentiful many years ago.

You are in possession of a unique piece of deep time.

To think that that is all that remains of a creature that lived about 100 million years ago...

Heck of a wonderful conversation piece.
