Knightia or Diplomystus?


Top Trilo

Recommended Posts

I bought this prepare your own fossil fish either knightia or diplomystus so I could prepare something for the first time which is why it looks like this don’t judge. I was wondering two things actually, one is it a knightia or diplo? And two are all green river fish this hard? I know I didn’t do a good prep job but was the fish poorly preserved as well? It was paper thin in some places and the fish doesn’t look whole it looks like its bones got moved after it died. Oh it’s also about 3 inches from the mouth to the “end” of the tail5573D3C8-FFA4-4028-8D3F-59657AB8EC35.thumb.jpeg.e9d45301c50d5755b292341adbc684c1.jpeg

It is a poorly preserved, disarticulated specimen. 

The easily identifiable features are not present. 

I would say it's a Knightia, but I'm not sure how you would go about proving that. 

I'm not seeing the humped back, thickened post cranial bones, fins, caudal fin, or body shape of a Diplomystus

But again, it is a very poorly preserved specimen. 

The thickness of the tail that is showing, and the size lead me to Knightia for this.

Thank you Tim, when you say its a poorly preserved disarticulated specimen, are you saying its not only because I did a bad prep job, its actually that I did a bad prep job on an already poor specimen right?

I don't know that you did a bad prep job. ;) 

But yes, it was badly disarticulated and poorly preserved before you even touched it.  :b_wdremel:

Thanks again. I guess since it is my first time I shouldn't be comparing a badly preserved fish to the fish prepped by Ptychodus or RJBs crabs. I hope to get there some day though :)

That seems to be an example of what I call an “exploded fish”. For that specimen and for your first fish prep you didn’t do badly and you got experience that will help you on your next one! I am curious about wether there are too many pieces for just one fish or if there are parts of multiples in there along with the more complete one. And don’t worry! They aren’t all like this. Each prep job is it’s own dance and experience. Some come easy, some come hard, and some don’t come at all. But they are all worthwhile in my opinion! Good luck on your next one!

Thank you, I will definitely prep again and I've learned things since then that will help.

Yep even if it doesn't turn out as well as you hoped every prep is a learning experience. I'm currently halfway through a very difficult prep that from a monetary perspective looks like the piece won't be half worth the time I'm putting into it. However, the learning makes up for the (somewhat) wasted hours. Keep at it, I look forward to seeing what you do next.
