Hollie Bird Posted September 30, 2020 Share Posted September 30, 2020 Hi eveyone I bought these fossil insects online a while ago now. Seller said they were from the crato formation in brazil. I would love to know peoples thoughts on them. Are these sort of insects generally 100% natural? Also how are they prepped? Thanks 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted September 30, 2020 Share Posted September 30, 2020 Yes, they seem real. Prepped very carefully! It seems a water wash and gentle rub are used to reveal surface detail, and then pins if necessary. Sometimes, if they want to reveal more of the detail a 10% acetic acid or 5 to 10% hydrochloric acid solution is used, the specimens maybe transferred to resin blocks during this process. 3 Life's Good!

Hollie Bird Posted September 30, 2020 Author Share Posted September 30, 2020 I find it truly amazing that something as long dead as these insects can exist today with the level of detail they show!! 1 Link to comment Share on other sites More sharing options...

Me too. It's astonishing. I have looked up the prepping process for you and added it to my comment above. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Bobby Rico Posted September 30, 2020 Share Posted September 30, 2020 They look good to me . I also are amazed with any very delicate material that becomes fossilised. I had a couple of Christmas ago a cockroach purchased from a member here by MrsR as a gift. It also was from Brazil and quite lovely. Exporting fossil from Brazil has now stopped so they becoming more rare, I believe . Cheers Bobby Link to comment Share on other sites More sharing options...

What's so wrong with someone like me being in wonder of a common fossil which holds no great scientific value. Although not my country, not my laws, not my business i guess.

I guess there's not much wrong in you owning and being in wonder of a common fossil like this. However, it's difficult for customs departments to judge both the authenticity and scientific value of fossils crossing their borders and this should, in fact, not be their duty. Thus, what would you rather do as a country: risk fossils of scientific value being exported illegally, or just simply place a blanket ban on the export in general? Though, often, even with a blanket ban, it is still possible to export fossils, if you get the right permits (which, then again, is frequently a hassle and may be quite costly)... But, yeah, these are spectacular fossils! Difficult to imagine the rare taphonomic conditions needed for such preservation! These specimens look authentic to me 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
Wrangellian Posted October 17, 2020 Share Posted October 17, 2020 It's odd to see an insect fossil in this type of matrix, that looks as though it had to be exposed by scraping it with a scalpel. Usually (as in Green River, McAbee, Liaoning, etc) the insect is exposed just by splitting the layers, with at most a little pin work to flake off some thin bits of matrix covering the margins of the insect. 1 Link to comment Share on other sites More sharing options...
Pemphix Posted October 20, 2020 Share Posted October 20, 2020 Real imho - but as said fossils from Brazil are not allowed for export. Keep in mind, that esp. with insects there's still a lot of scientific work to do from this site.... 1 Link to comment Share on other sites More sharing options...
