Florissant Beetle to ID

[connorp]

Curious if anyone recognizes this beetle (?) from the Florissant Formation (Eocene; Teller County, Colorado). I had a look through "The Fossils of Florissant" (Meyer 2003) but did not see an obvious match.

Heteroptera 100%, something like stink bug, but can't say more than that

That's really cool. Find a few tiny bugs from that same stuff but nowhere near that big.

Actually decent insects don’t seem to be easy to find. I’ve visited twice in person and purchased a couple boxes of shale, and this is the only good insect I found.

Scudder 1890 has some similar examples from Florissant:

Definitely not a Beetle. it's belongs in the family Pentatomidae, generally called stink bug or shield bugs.  I'm  not sure about what genus.
