Testimonials

BRILLIANT! AMAZING! amazing too stellar customer service !!! love my ancient fossils!

Thank you In Stone Fossils!

Brianna Uriostegui

Placed online order. Fast shipping, great communication, great price, and best of all great product! Very happy with order! Highly recommend them!

Kevin Pete

Found this site while searching for Green River formation fossils. I bought 25 of what was said to be partial fish. Some of them were very good examples of partial fossil fish but about 10 of them were complete fish and very good quality. Some were a little light in details but still and EXCEPTIONAL VALUE, great customer care and service and fast shipping with well packed fossils. HIGHLY RECOMMENDED.

Phillip Dudziak

I was looking for a unique gift and found the perfect thing at In Stone Fossils. The fossil arrived, just as pictured, packaged beautifully. From purchase on Sunday afternoon, the package arrived on Wednesday! I am very satisfied and am looking forward to doing some more shopping with them!

Holly Pimpinelli

Great little fossil store. Museum quality pieces. Vast price range. Stuff for a couple bucks to $45,000. Did I mention Museum quality?

Joseph Spivey

Love it!! I ordered a spino tooth for my brothers birthday and he was super overhelmed. I got a very sweet handwritten card and even a gift! Super sweet people giving super cool quality fossils! I live in Norway, it literally traveled around the world and the package was still in perfect condition. I can recommend in every way and i will definitely order other things!! ❤️❤️❤️
