A nice Rheaboceras sp. from Cowley, Wyoming USA. I recreated the aperture. Quite a challenge to get colours and texture matching. #FossilFriday #fossilprepping #paleontology

Latest personal prep: Euhoplites nitidus from Escalles #capblannez #France. The most complete #shell I have seen. The last bulea and clavi are reduced in size. Suggesting adulthood. #fossilfriday #ammonites #fossilecapblancnez #capblancnezfossils #Fossilprepping

I polished two cretaseous #marcasites (pyrite nodules) from the chalk at #capblancnez #France I collected these while #fossilhunting. They become very pretty! Polishing #pyrite is a hell though. The black cutting water is very hard to clean up. #fossils #beach #cotedopale

Again an #ammonite from Aube /Courcelles #France for #FossilFriday. This time a Hoplites bennetianus. The preservation is awsome! Also for a client.

Hoe bepaal je hoe laat het is als je stenen onderzoekt? Vraag het de ammoniet! Deze fossielen leefden in de zeeën langs de huidige loop.

Sadly I wont be joining you this year. Enjoy!
Our very own paleontologists are headed out for their 8th dinosaur fossil dig season out on the Jurassic Mile in the Big Horn Basin! Stay tuned throughout the summer for dig updates! Here's a little about what they study while out there: https://t.co/vg4LQloJjc

The #Opal is not a valid mineral but mineraloid. However, opals have outstanding variety of forms and colors - from precious colorful opals to clear hyalite or common opals. Learn more in our in-depth opal overview: https://t.co/b79rp13RO1

Opal is a colorful variety of silica, most valued for the play of colors it exhibits.

The last few times I was @DinolabN I worked on a #triceratops sacrum. #beforeandafter Its tough going, its very fragile. Prep, glue, prep, glue etc. Small steps keep this bone in one piece. #dinosaurs #fossils #fossilprepping #museum

Play of colour in precious opal comes in 2 ways: the normal way and contra lux. In the last colour is created by light coming through the stone. It happens more frequent when silica source is vulcanic ash. #opal #gemstones #precious #colours #gemcutter
