I'm entering my first crocodile vertebra. I found it 4-14-17 along the Potomac river at an exposure of the Aquia formation. The layer here has lots of bones, but most are unidentifiable, so this made me pretty happy. Most of the bones here, including this one, have a lot of (limestone?) matrix stuck to them, and I haven't figured out how to remove it yet.

Actually the substrate of the Aquia Formation tends to be glauconitic sand, or in some cases a type of marl (not limestone). Marl is a form of calcium carbonate, and should dissolve in diluted vinegar without affecting the calcium phosphate that makes up the bone.

I've tried vinegar, it doesn't work. This piece soaked in undiluted vinegar for a week or so without any difference in the matrix.

Then it isn't marl or limestone. My next best guess is just hardened sand (essentially sandstone), possibly with iron oxide/hydroxide acting as a sort of "glue" along with specks of calcium carbonate material from shells. It could also be calcium phosphate leached from the bone into the original substrate.

Any ideas on how to remove it?

 

 

Maybe just try scratching it off with some prep tools, there can't be that much on it. Otherwise maybe try Iron Out or a similar product on a test sample of the same matrix and see what happens.

 

If it's leached calcium carbonate phosphate then physical assertion is your only route of attack as far as I know.

Here is a coral i found on april monday the second in the department of Charentes-Maritimes in France on a kimmeridgian layer.

According to my documentation it is, a priori, a Pseudocoenia hexaphyllia.

IMG_0010.thumb.JPG.7aa7ce8bb8068c0ee8da97360dacf9ce.JPG

The name of Pseudocoenia is, for some zoologists specialized on the corals, synonym of Stylina.
