Need ID for fossil.

These are gifts that my father bought for me in his trip to Brazil more than 20 years ago. Knowing the country, I request this ID assuming what I have is probably fake. Attached photos. 2 specimen, I think both actually exist in present time.

They look real to me including the cricket in the first and last photo.

My goal is to leave no stone or fossil unturned.

These are real fossil insects, most likely from the Cretaceous Araripe Basin, Santana Formation in Brazil.

Looks like a very nice cricket, and not sure about the other - maybe a coleoptera?? Don't quote me on that.

Check through the PDF's that are listed here.

Nice acquisitions!

Thanks for posting them.

I believe the second (square piece) is a type of Cockroach.

The first appears to be a large, flattened blattodean or cicadomorphid; the second looks like some sort of orthopteran.

I think that, based on the size of the cerci and ovipositor on the first fossil, ... that it is a cricket.

The square shaped stone - not sure there is enough detail to be able to ID it, one way or another.

As far as the cricket is concerned, thanks for all the help in identification. In a way I was sorta testing to see how many respondents are knowledgable about ID of a fossil I already know. (I loved the study of entomology since I was a small child.) A female cricket is certainly the first specimen. Thank you Tim for clarifying on why it is a cricket. And DPS ammonite and Runner 64 for getting the ID spot on for the round fossil. The square fossil on the other hand... I knew it is some sort of moth, but the details are hard to see. Based on memory from what my late father told me, the second fossil is a moth, unfortunately any further details is up in the air.....

There appears to be preserved color patterning on the moth's wings; this might aid ID.
