Hello. Every once in a while I see these "juvenile Diplomystus" listed on our favorite auction site. The fins seem to match Diplomystus, but it would be great if someone with more GR knowledge than me could shed some light. The little guy is 1" long, tiny :)

I'm not sure how they can ID these when they haven't fully formed yet, unless the professional diggers/paleontologists know for a fact this is what they looked like.  :headscratch: :unsure:

I suspect it may have something to do with the number of vertebra in the spine,or the shape of the skull/mouth.  :shrug:

 

These aren't a great display fossil, so, I resist paying what they want for some of them. I'd only be willing to spend a few bucks on one of these. 

At the prices they are listed at, you could get a nicer specimen of a different fish. A few dollars more, and you could get a prep your own kit.

I suppose you're right about that. They are a little pricy. Thanks for the info :)

This is my “juvenile Diplomystus”, at least I think it’s a juvenile. It’s 1.75 inches long and looks very similar to my adult one. Not the best preservation, but for £3 it was hard to turn away because honestly I liked the small size, regardless of what it really was.

 

 

Yours is so tiny, it’s hard to make out any defining features. Unless it’s a very low price, or if you’re super in love with it, I would pass. :(

It can be tough to ID juvie fishes from the Green River Fm.  A nice in-focus photo would make it easier.  : )

Cool! I only recently found Grande's information on GR fish. I've been gleaning through it, interesting stuff! That first picture looks a lot like the fish I have here, but at this point I think I'll look for an older diplomystus with more detail. :)
