The first fossil Proscopiidae (Orthoptera: Eumastacoidea)

This is a little outside of the general scope of BugGuide, but I thought that other members might be interested... I have recently published a paper describing the first fossil Proscopiidae. The specimens are from the Early Cretaceous Crato Formation of northeast Brazil and you can view a photograph of the holotype here along with a reproduction of the abstract and some links to press coverage. If anyone is interested, I'd be happy to provide a PDF reprint of the paper itself.

Best wishes to all,


That is a beautiful specimen! Brazil definatly has amazing stata!!

It's a great specimen
Apart from the holotype and paratype specimens, I'm not aware of any other proscopiid fossils from Brazil, or anywhere else for that matter. The fossil insects from the Crato Formation are truly wonderful to work on.

Isn't that always the way?

Here is the most amazing Orthoptera specimen that we have in the Stonerose collections. Its not from Washington though, its from "Grant County, Montana"

This is indeed a very nice specimen; I'd love to see a higher resolution image of this and would be very grateful if you could send one to me (

Best wishes,


I have sent a higher resolution image to you email. Let me know if there are any closeups you would like and Ill try mey best to provide them.


Thanks Karl
Much appreciated... it's a great specimen. I would be very interested in studying it, as it will fit in nicely with other work I'm doing on fossil tettigoniids in amber.
