I believe it is green river so 50 +- million.

The Florissant Formation is Late Eocene/ Early Oligocene; +/- 34 MYBP.

This is a wasp from the U.S. Florissant Fossil Beds website:

I think Rockwood's is something else, as the head and thorax on his are proportionally smaller.

Maybe a robberfly, or even a winged ant?

Do these typically come in swarms ?

In my (modern) experience, no, robberflies are fairly solitary.

Hope you don’t mind me cropping and lighting your bug.

Not at all. Might even make a good trout fly if you get it light enough. :)

I found a few that could be. I'll keep working on them.

Well I was close. Only 16 million off, that is not to bad.:blush:

The quantity does appear to favor the winged ant ID. Here are the last three.

You were spot-on for the Green River Fm. :)

I would like to add a note to anyone visiting this site. There is no doubt in my mind that the folks who run the quarry would have identified this for me. I just chose to use the time collecting.

I ended up sleeping from Chicago until somewhere over Vermont as it was.

Collectors should all put this place on their bucket list, and parents should pack a picnic lunch and introduce the young ones to fossils out at "gramma's" quarry. :)
