Fossildude19 Posted July 15, 2018 Share Posted July 15, 2018 Check the crystals by putting a drop of vinegar on one. If it fizzes, it is calcite. If not, it is quartz. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Coco Posted July 15, 2018 Share Posted July 15, 2018 Yes I think. But you have to take from now on the good habits : size of the sample, the origin (a little more precise than Kansas !) and age of the sediment when you know it Coco 1 ---------------------- OUTIL POUR MESURER VOS FOSSILES : ici Ma bibliothèque PDF 1 (Poissons et sélaciens récents & fossiles) : ici Ma bibliothèque PDF 2 (Animaux vivants - sans poissons ni sélaciens) : ici Mâchoires sélaciennes récentes : ici Hétérodontiques et sélaciens : ici Oeufs sélaciens récents : ici Otolithes de poissons récents ! ici Un Greg...

DPS Ammonite Posted July 15, 2018 Share Posted July 15, 2018 The lower left part of the first rock appears to have a high spired gastropod, point facing up and aperture facing towards viewer. (Or, is this a case of pareidolia?) I cannot quite make out the crystal forms from the photos. If the long prisms of the crystals have six faces and the points have six faces (hexagonal crystals) then quartz is likely. If a knife blade cannot scratch them then quartz is likely. Please test them. 2 My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

Wrenchchik Posted July 15, 2018 Author Share Posted July 15, 2018 The crystals scratch with my thumb. I thought my hand was good for scale. Ellsworth County, Kansas. Yes definitely some kind of gastropod. I found several others also. 1 Link to comment Share on other sites More sharing options...
ynot Posted July 15, 2018 Share Posted July 15, 2018 I think they are selenite crystal. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."
