Green river formation fish


Recommended Posts

Got a sweet slab of green river fish today but I’m not sure on what type of fish they are, I’m pretty sure ones a knightia, but could someone give me an ID on the others

I think the big one is a Mioplosus, the others are probably Knightia Alta. But let’s see what the experts say.   Very nice find.

They all look like Knightia to me.

I agree. All are Knightia eocaena from the split fish layer of the GRF.

I also want to know whether or not these are Knightia alta or Knightia eocenea.

And I already know that three Knightias in the one slab of rock are eocenea because someone here told me, thanks.

No paint, natural. Notice the small brights spots of matrix within the brown areas. You will be having a hard time painting this that detailed.

You may have probably seen this specimen of Knightia, which is largely an impression and also unpainted:

When in doubt you can look to the fins as well. It's very difficult to paint those in detail that shows the alternating matrix and fossil colors between the spines. Even if someone was that talented it wouldn't be worth the time to paint them.

They are all Knightia eocaena.  (note spelling).

 

Knightia alta are much wider:

@Top Trilo no it didn’t :) Knightia Alta just has a thicker body than knightia Eocena

Yes, that’s what I meant to say.  I know K. alta are much fatter but it was late and I was tired when I answered.
