Fish

[Fossilcollector4]

I was wondering if anyone knew the identification of this fish, and if it is a  genuine fossil?

Knightia eocaena, Green River Formation.

Perfectly genuine - a rather nice example compared to some I have seen out there.

Not saying Tim is wrong, but I want people to be aware of the miscellaneous cenozoic fish that resemble Knightia:

I agree with our friend Tim . It is a genuine fossil of Knightia eocaena bony fish, dated between the Eocene and Paleogene (approximately 50 Million years old). Green River Formation - Wyoming - United States. Congratulations, it's a beautiful fossil and worthy of any collection! By the way, before I forget, Knightia fish lived in the freshwater lakes and rivers of North America and Asia.

Yes,I noticed the university

Unfortunately not every fish that is a likely Knightia is possible to be accurately identified, even more so when all that is left out of the mouth is just the tail!

Just looking at the rock tells me Knightia.

I agree.  That is what I thought as well. 

The matrix is unmistakably Green River Formation matrix.

Also, if you take into account how prevalent these are on the fossil market, Occam's razor comes into play.   

I've never seen much in the way of other Cenozoic fish for sale. At least, not in the price ranges I look at.

Ive seen some purty nice fish, and I can afford them, but I almost never spend that kind of moneys!  and what is Occam's razor?

Ron, Occam's Razor is a problem solving principle. It states that when you have multiple possible answers to a problem, choose the one that makes the fewest assumptions.

Ive been around for 60 years now and I have never heard of that.  I must be spending too much time under a rock?

No, just not reading Scholastic philosophy (13th-15th c.). Very arid and plodding stuff; you probably didn't miss too much.

That is not possible, You can not spend too much time with rocks.

[doushantuo]

Totally agree with Ynot
