Recently I took a trip to a new spot in the Maastrichtian of Maryland. I did not manage to recover too much vertebrate material, though I have been quite intrigued by one piece that I collected. The main question regarding this piece is whether it is bone or whether it is simply a suggestively shaped rock. If it does turn out to be bone, would it be possible to determine what it may have come from? The main marine reptiles that are recovered from these deposits are mosasaur and marine turtle. A few photographs of the specimen in question. If better photographs are needed/photographs from a different angle, I would be more than happy to attach some to this thread. Thanks in advance for all suggestions and opinions!

I’m very curious about these “ripple marks” that I have seen posted a few times on the forum. From what little research I have been able to do (so far...) they seem to be caused by wind or water erosion of the rock. However, there is mention of them possibly being fossilized rippled sediment from the floor of a body of water. So... are these geological erosions or some type of fossilized evidence of water movement? I can see how the erosion would work, but wouldn’t the sediment be compressed during lithification/fossilization and destroy the details if it was from a body of water millions of years old?

Finally got around to my bucket of unwashed rocks and discovered this. Don't know what to make of it, it's either Cretaceous or from QAL. It was so pretty wet I put a flat clear coat on the top side to bring out contrasting colors, bottom and side are natural. Kinda looks bonyish or turtlish heck I don't know!

I am just stumped on these. All came from banks of canal at the bottom of a hill. These are all on the shallow level side of canal amongst sandstone, and they are everywhere. On other side of canal a little further down it's grey clay with big red concretions and fossils shown but these aren't present. These whatever they are aren't very heavy but hard like limestone. Only found one with inclusion, and broke one open and it's smooth. Included pictures of both. They kinda stick to tongue.

I have mentioned before that I typically grab two or three random non-fossil geological pieces when I am out hunting. They either go on my “cool rock shelf” or to my rockhounding twin. Here are a couple of my latest finds. Both were from the same limestone road cut in central Kentucky. My knowledge is very much lacking in identifying minerals, and really anything geological that is not fossil related, so feel free to chime in with any info. However, I’m not specifically looking for an ID. I mainly wanted to share. I found them interesting and thought others might too. I think this one is a calcite(?) deposit inside of a void (vug?) in limestone. I actually found two of these still sitting nicely in the rock like this. I have seen them before, as they are fairly common around here, but they are typically eroded out and laying loose on the ground. Here is the larger one still stuck in the rock. front side: back: This is one such deposit that eroded out of the limestone. I found it interesting that it looks to be two minerals mixed together. I think calcite(?) and quartz(?). The back is rounded and has matrix stuck to it indicating, to me at least, that it was once embedded in the limestone. Anyway... I thought they were neat and wanted to share. These minerals are found in my area a lot, but I don’t typically see them in this fashion. Enjoy!

KYANA Geological Society Annual Mineral, Gem, and Fossil Show
FossilNerd posted a topic in General Fossil Discussion
The KYANA Geological Society is hosting their annual mineral, gem, and fossil show next weekend (Nov. 22-24). I attended last year and it is a small, but fun event. I’m not sure which day I will be there, but I plan to take the family. Just passing along the information in case anyone is in the Louisville area and would like to attend. If you can’t make it, don’t worry, I will come back with a full trip report. http://www.kyanageo.org/showflier.htm- 28 replies

This came in a big box of mixed fossils. This is an orphan without a label or bag. It looks interesting, like a cross-section of something in the rock matrix. The object is circular in profile and cone or tooth shaped. There appears to be more than one of them, but the other is still partially obscured by matrix. Is this a mineralized fossil of some sort, or is this just a strange geological specimen that got mixed in? Could this be some kind of stromatolite? I wish I had some locality info on it, but I don't. Any help would be appreciated.

ID needed: Mystery rocks / minerals in my collection.
ziggycardon posted a topic in Rocks & Minerals
Hi, yesterday I did a bit of cleaning in the fossil room and my mineral showcase and I realised that there were 2 stones and 1 stone/mineral which I still don't know what they are. Perhaps someone here can clear things up? The first is a button shaped, with something resembling growth rings in the middle. I've had this thing for as long as I can remember, I got it as a child when it was part of a magazine for kids that included a rock or mineral with each issue. But I lost the magazine and I have no idea what it is. And then the other mystery items are two metallic rocks that were found when we were excavating our swimming pool in the back yard which is in Tongeren, Belgium. They are as said metallic, have some edges that seem like they are molten, they are very magnetic and are extremely heavy for their size. The weird thing is that they were found in a clay soil, which seems to me an odd place to find metallic rocks? So are they geological? Or are they perhaps manmade? The only weird thing is that there has neven been any construction in that part of the garden before and we are the first building there, it was just an empy lot before. Perhaps historical? I live in the oldest city of Belgium, we have archeological remains of the Gauls, Romans, and so forth and according to liguists the name of the village I live in derived from the Latin word for Smithy, so perhaps a remain from an old smithy? Or perhaps even a meteorite, although that seems very unlikely since no meteorite has ever been found near. So I am very curious about what you all think. Thanks in advance!.jpg.132df94937f0b4ea80fb13104865483e.jpg)

I’m gonna need some help on this one... I’m not even sure whether it’s a fossil or just geological. Found at Sugar Creek in Crawfordsville, Indiana

Found this piece while digging into the hillside behind the house near lake Wister in Southeast Oklahoma. The area is primarily Pennsylvanian and I have found some beautiful specimens on the land. There are a lot of limestone and sandstone ledges and outcroppings all over the property. I do t see any tooling marks on the edges so believe the shape is natural but not sure what the texturing is. Any help would be appreciated.

I found this in a dump on the edge of town. Not a property dump or minden, just a dump in a tree line at what used to be just outside of town and is now developed. It did not at all seem to have been a burn pit, it is not near a waterway, nor did it yield anything terribly interesting, but this. I got nuthin.....

I know that jade is practically non-existent in and around Wyoming by now, but this looks very unlike serpentine or amazonite or unakite. I believe jade has an outer crust similar to this piece I found, but I have found nothing like this in PA nor here in Colorado/Wyoming so I have nothing to compare. You might not see it well in the pics, but the light from the phone doesn't get through the thicker part of the rock but does illuminate the material at the thinner end. Please help ID. I will post more to follow

Hello, I found this at the beginning of 2018 and haven't given it much thought until I saw the post from 2016 about a strange specimen that looked like Native Americans carved. The topic has been linked below. Below is the specimen I found and was curious if its the same process and is also counter septarian? I also thought they might be beekite rings. Any thoughts and ideas would be greatly appreciated. Best regards, Paul

Gorgeous Complex Rock/Minerals Containing Microscopic Fossils
InfoHungryMom posted a topic in Rocks & Minerals
I was looking for specimens with barnacle plates and rediscovered many UNBELIEVABLY GORGEOUS rocks/minerals/microscopic fossils - an iPhone does not do this justice. “Inside lighting” makes it appear blue/green. When viewed outside, it is fabulous purples, greens... this “rock” is quintessential Israel. No matter what your religion is or isn’t- there is a spiritual feeling gained just from being there. This rock represents the best of that to me- ancient, diverse, mutualistic symbiosis,...

Hi all, While sifting for sharks teeth in the pebbles we came across these different looking ‘stones’. The top and bottom specimens are the ones we are questioning. Stones? Seeds? Scute? (Top one). Any help would be welcomed. Thanks in advance

Again, it's small enough that pics are tricky to get with my phone. I've posted the interesting side, the side, and the flip side. What do you think?

Hey Hi Boys and Girls, Ladies and gentlemen, and all others! I have noticed that the phrase "It is just a rock" is used quite often when a non fossil rock is posted for an ID. I think that this is a bad choice of wording that can cause confusion. Most fossils and all trace fossils can be described as being just a rock also. (lithified life) I humbly request that We refrain from using this terminology to describe a non fossil rock. Regards, Tony

Hi all, I was recently introduced to a really neat website that allows you to look at geological maps similar to google maps. The only problem is that I don't know what age the colors correspond to, or what the acronyms such as Tma, or Tmf stand for. Where can I find a list to identify these? https://ngmdb.usgs.gov/ngmdb/ngmdb_home.html Thanks

Is this a fossil? Or just a rock?
-
Found these in the San Angelo formation near Grape Creek, TX. I'm not sure what to make of the (as if that surprises any of the regular contributors in this forum). There were plenty of rocks in the area but these were different than the rest. On the first item the exterior is fairly hard but the interior is softer and disintegrates easily. I'm guessing a softer limestone? The second is is very dense and has similar patterns to the belly of a tortoise or turtle. Any help or direction would be appreciated and thank you for your patience. Michael

hi guys, would just like to mention again how helpfull and interesting this well run forum is. I am wondering if anybody has an idea what this specimen is ? Location is 'somewhere in australia', from an old collection i aquired, item is 466 grams, and 15cm wide cheers, kevin

Found this interesting stone with white wavy lines running through it. The lines are not solid but have a segmented look to them, and are slightly raised in texture. It has a somewhat fibrous texture that reminds me of petrified wood, but this looks nothing like the brown or caramel colored jasper-ized wood I find around here. Found in the Palmer Divide area of Colorado, Cretaceous. Is it something interesting, or just a pretty rock? It is about 4 inches square. Thanks for peeking

I'm quite sure all members of the TFF have purchased a book in the past , present and perhaps in the future on topics relating to the geology and the fossils you hope to find in your part of the world. So whose going to finish that book this year and complete the promise you made to yourself. Tell us what your reading....i love a good book. ( I can just see you leaping to your bookcase now ). Regards, D&E

While returning from another fossil collecting trip, photos posted later, I took a photo of this geological formation. Can you name the site and the state? I'm off to North Dakota, (collecting with FF member Bev is on the agenda) so will check in when I can. PS: Albuquerque Rock and Fossil show is coming the first weekend in October, I'll be there, hope some members will be also. More on this later. Jim Old Dead Things
