I am fascinated with the honey comb coral! I am still very new to rock hounding so i do a lot of reading about fossils and minerals, but i am stumped! I found some gorgeous stuff this weekend but some of it looks different than the honey comb coral. It really looks different! How do i tell which is coral or petrified wasp nest? It really looks like a wasp nest you would find on your home under eves! Thank you for your help! Also how do you upload pictures? I would like to put the pictures on here to show them but i can't.
Hello Jessica. The way you post attachments is you take the picture and with the aid of a photo program, make the file so that it is...I think, less than 120 KB. Then, below the message box you'll see "manage attachments". Click on that and it should allow you to upload your pictures. If the file size is still too large, go back to the photo program and shrink it some more.

I hope this helps sorta'.

Jessica, where did you find them and in what type of environment? (mountains, beach etc)
jessica koehne
I found them along with some beautiful horn coal in Osceola, Mo. i found them along some creek beds. Plus i found them along Osage river. Part of or trip was flat and them we came upon a very steep rocky area. That is where most were found. Also can geodes happen in sand stone? I have a few geodes and have never seen one in sandstone. I found a stone with quartz on the outside, i was an idiot and broke it and it was completely filled with quartz and smokey quartz. I am attaching more pics of the coral. Thank you for helping! You are the only one that has answered. I am new at this stuff and have only been on this a couple time.

Here are the quartz I was talking about. The black rock isn't sandstone but the others are. The crystal is more like a cubic shape and they are very fragile, coming off in layers. The rock that has the small pieces is the one that was more like a geode or nodule. Thanks :-)

I can't answer your questions much about what your specimens are - I figure that they are some type of coral - very doubtful that a wasp nest would petrify - they would fall apart if they got wet - would need to be something much more durable to have the possibility to be petrified.

even with pictures it is often difficult for items to be identified - give the "ists" who visit this site a bit of time and they will no doubt offer their very educated opinions as to what you have found

Mike Streeter
Hey Jessica,

Looks to me like your so-called petrified wasp nest fossils are actually colonial coral fossils.  These are not unusual for the area you collected them.

Jessica, I THINK (anyone out there please help me on this) "geode" is a round stone with a hollowed-out part. So I can't see why a sandstone cobble with a hollowed area can't be a geode.
Jessica Koehne
Thank u. Now i am anxious about going back to see if there are other geodes! I really hope that is what it is. We have found some nice chunks of quartz covering other sandstone rocks. Next time i will be a little smarter and not break it open like i did! Thank you guys for your help. If anyone know some other nice places to go rock hounding in Mo i really would love input. So far the only things we have found is some drusy, some geodes, horn coral and the other coral. My kids have a blast hunting to, my 9 year old girl wants to be a geologist! :-)
Jessica, I'm thinking the quartz you found is probably druse -- means it forms in a crust like formation on other base rock - i.e. the sandstone - it often forms within pockets/open spaces in the limestone/dolomite in this area of Missouri.   Anyway that is "possibly" what you found -have never heard of sandstone geodes but the only "ist" I am is hobbyist so I can not really say for sure.

you might consider going to the Missouri geology store and perhaps get one of their rock & mineral kits for you children - it has samples of the rocks/minerals found in Missouri along with a booklet with information about them.

the Missouri state stone - Mozarkite (name combination of MO for Missouri, ozark for the region and ite "rock") is found near Lincoln Missouri.  In the fall, I think 2nd weekend of September, the local Rock & Mineral club there has their show and they do fieldtrips to collect it.   I keep hoping to make the trip over for it but so far haven't done so.

I live near Salem, MO and in this area we have druse quartz and calcite in fair abundance, with occasional finds of bits of weathered pyrite/marcasite, hematite and limonite.

you can scroll down to the bottom of the page on here and find a link to McRocks field trip reports and perhaps find some ideas there too.   not sure what area of Missouri you live in or distance you will travel for rock collecting.  Geodes are found over in the Keokuk area in the northeast corner of the state - again in the fall they have a big geode weekend event or the various geode mines are open throughout the year, weather permitting.

perhaps you could post pics of the quartz sandstone find and that might help folks identify it.

Docea, I live in warrensburg, Mo. The man I am engaged to has a daughter that lives in Salem. I am not sure if you would want to show me the ropes , but I would love to go out and learn! My 9 year old would love it too, she loves druse and so do I. Plus I would love to find new stuff. We don't have much here, plus I am not sure how or where to look. I have seen some pics of the druse you have gotten on other subjects on the board. I would love to learn if you would be willing? Did my quartz pics not show up? If they didn't tell me and I will try to post them again.
jessica koehne
Docia, i am sorry i spelled your name wrong. Maybe if you are ever my way we can go geode hunting. I know a place to find them. We found 6 through the winter, just waiting for a good rain again! :-)
jessica Koehne
Docia, I am an idiot and somehow list your email. Computers hate me! Any chance you can resend it?
Kimberly Berry
Any idea what this is? Found it on our big sand hill. Mid Michigan, no real water nearby. ..

KIMBERLY,      You have found a piece of a fossilized colony coral. They are common in the Ordovician and Mississippian age sedimentary rock thru out the Midwest.
And, looking thru the earlier postings on this thread, there is no such thing as a "petrified wasp's nest". 
Timothy Boone
I believe your wasp nest to be fossilized Rugosa Coral. I have found and thought the same as you before.
