Starting at the Beginning

Great find!

If only it was complete, But it is still awesome!

Yeah it was definitely weathered out, the reason why I couldn't find the rest of the amphiscapha is because that was the end piece poking out. Sadly I found this a few days before I moved (go figure lol) but I have found huge bellerophons in the Kereford limestone before but never trilobites. The exposure is really small compared to stuff down in Kansas but if you are prepped for some knee deep river action its an alright place. I might be heading back later this month as im doing an independent study on my old fossil sites/giving the localities to my geology professors for future students to enjoy. Ill have to quickly make a few other glances and grab some slabs when I head back up.

Great find! Was the specimen weathered loose? I ask because the elusive Ameura trilobites I found in Nodaway County had either silver, or a chocolate brown colored shell. Most of the weathered out specimens had turned a white coloration.
It's definitely worth going back out to that locality, and looking over that specific layer well. I would be trying to pull large slabs of it out, if possible to take home and carefully split.

Thank you for the information.

This is not a pecopterid but rather some neuropterid.

Magnificent fossil collection!

Now I read your post over again I think I understand it is a DP4 Tooth, Thank you @Harry Pristis!

So would that make it a P3? I can't seem to find one that looks like these.

Stunning!
