fifbrindacier Posted February 27, 2018 Share Posted February 27, 2018 Hi, i tried a new spot : marls from the Maestritchian with ridges of marly limestones, above them are limestones from the Dano-Montian. There, according to the geologic informations i have, you can find Pachydiscus, Hamites, Echinids, Inocerams, Brachiopods. I found this piece and i first thought it was an oyster, but now i wonder if it could be a part of a rudist. It is about 11 centimeters long for about 10 centimeters of width. The whole block is very heavy. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

fifbrindacier Posted February 27, 2018 Author Share Posted February 27, 2018 So if it's not a fossil, those strays must have occur when the stone detached and fell, or could there be another cause ?

fifbrindacier Posted February 28, 2018 Author Share Posted February 28, 2018 Thank you all for your answers, funny slickenslides so, and probably shell bits but i'll only know it when i'll crack it up.

abyssunder Posted February 28, 2018 Share Posted February 28, 2018 Without a transverse cut (perpendicular to the fibers axes) everything is just a guess. It could be geological (like satin spar or similar), petrified wood, rudist or something else.

fifbrindacier Posted March 20, 2018 Author Share Posted March 20, 2018 As @abyssunder asked i cut it perpendicular to the striations.

abyssunder Posted March 20, 2018 Share Posted March 20, 2018 When I said a transverse cut, I was referring to a transverse section through the specimen. We have to see how it looks in transverse section.

ynot Posted March 20, 2018 Share Posted March 20, 2018 The new pictures show the features are surface only and the "grain" of the rock looks uniform. I am still thinking it is not a fossil.
