Modern Coral How To Get It Out


TMD23

Recommended Posts

Hello,

I am brand new to your forum but I enjoy reading through it. I have lived in Illinois for the past 26 years but I recently got back to my hobby of rock hunting

I went out the other day and I found Modern Coral fossils. very large amounts of them and some are some 2-3 inches around., some are pointy but most of them are stuck in what appears to be Limestone. Some have crystals in them that you can see from the top.

How do I get them out?

I tried a hammer but I broke the fossil not the rock! Now I am kind of stuck trying not to break any more!!! can anyone help?

thank you

Tim

Welcome TMD23 from Northeast Illinois. A muriatic acid and water solution should dissolve the limestone. You may want to research the process a bit before attempting to do it. What county were the fossils found? Depending on the matrix even vinegar may dissolve the matrix. Anyway.. welcome to the forum!

well thank you! nice to hear form a local. I found them in Will county there seems to be a very large deposit of them along the river but up on the shelf above a ravine I found some then more then allot more I couldn't possibly touch them all., it looks like a very healthy reef was at this site. I am hoping to find a fish or bird in all these. there must be more than just coral and ferns here at this site the reef looks to have been huge.

thank you for your reply though.

Don't know if it will work for you, but I've had luck getting mudstone off of fossilized shells without damaging the shells. It involves using a vibratory tumbler and soluble oil and water. This will take off mudstone but has no effect on other types of rock. I'll send you the details if your interested.

Ron thank you! I think any advice is good advice. I will try the vinegar first then the muriatic acid then your method. this is true limestone sop I am not sure your method will work on it. but I am open to try new things. thank you!!!!!

Since you have abundant samples at your disposal, you are in the enviable position of being able to experiment with techniques for their extraction. Practice!

Hi, and welcome to the Forum. :)

For some clarification, can I ask what you mean by "Modern Coral fossils"? :unsure:

Regards,

Wow this is quite overwhelming. Thank you all for your input and welcomes! Thank you to the UK for your support.

I have only named them Modern Coral because the Internet showed a picture of something that looked like my fossils and they called them that. I am not sure if it is correct or not.

I will post pictures tonight of some of what I found.

Thank you all again.

You must have the best fossils out there.

I know about muratic acid for sure. I just never thought of it as a rock dissolver

Thank you!
