This mold seems large to be from a Crinoid stem. It’s almost 1 cm in diameter. But I can see faint horizontal lines that the camera is not picking up. Any help or guidance appreciated.

I apologize, I am not used to dealing with dolostone of this hardness. The rock of the Niagara Escarpment is serious stuff! What type of equipment besides cold chisels, dental tools and hydrochloric acid should I consider purchasing?

Hi all, I found this rock with an assortment of fossils in Israel and i am looking to find an answers to some questions i have out of curiosity. Info: Location found - Ayalon Valley River, Israel Mineral - The stone is Limestone with partially metamorphic dolostone The fossils and the imprints are crystalized, if i were to guess i would go with dolomite or calcite crystals. Basically my questions are: What type of fossils are these? From around which period are these fossils and imprints? Is it usual to find the variation found here? What is the best way to clean it? Thanks!

So I need help identifying Limestone and Dolostone from each other. I would like to be able to properly id, describe, catalog, etc finds. This also would help me date my finds. From what I know from Wikipedia is basically dolostone, is limestone, that dolomite replaced the magnesium in limestone. Obviously limestone contains high calcium carbonate. Dolostone can come in brown, pink, and white colors. Also I have seen pictures of grey colors as well. This is confusing as what I know as limestone comes in white and grey. Dolomite also crystallizes? Would this make it appear to be more grainy like sandstone? Can somenone break this down to me? Basically articles on the internet just tell me over and over dolostone contains dolomite! Arghh! Lol. Feels like I am banging my head againt a wall! Thanks for your help!!!
