Hi there!
I’m very new to the forum. I’ve recently been collecting various specimens - crinoids, fish, brittle starfish, trilobites, etc. I’ve come across the attached Cordulagomphus. The seller has said he/she purchased the fossil from a shop in Tucson, Arizona in the past and that it was found in Brazil, but I’m almost scared it’s a bit too good to be true, and I don’t want to get burned after paying the price. Can anyone take a look and tell me what they think? I really appreciate it!
