  1. Hello everyone, Yesterday my girlfriend & I went fossil hunting for birthday. This was the first fossil hunt the two of us did on our self, our previous hunts were all excursions with the Belgian Association for Paleontology. We visited two locations, but locations are part of the Formation of Gulpen, around 68 million years old, dating back to the Maastrichtian (these outcrops are part of the Maastrichtian type location where the first mayor Mosasaurus discovery was done). The first location we visited was a limestone outcrop next to the Albert Channel here in Belgium, only a 20 minute drive away. I discovered this outcrop while looking out the window whenever I drive to Maastricht and yesterday we decided to check it out. It is quite a little outcrop, no more than 70 meters wide, but one of the few places left where you can hunt in Limburg. We hunted here for around one and a half hour and we only searched the fallen and loose bits of limestone that were the results of erosion. We didn't want to start hacking in the rock. We mainly found ancient sea shells of different species and some bryozoa's in this location. And a some pieces of wall where teeming with urchin fragments, but we didn't find any intact one near the surface. But since the urchin graveyard was deeply enbedded in the rock and we didn't want to hack in it, we left it as it was The second location we visited was the "Grote Bos" in Beutenaken in The Netherlands. Here there are holloways in the forest that expose some limestone outcrops. This spot is known for it's belemnite which can be found on the forest paths, because the soft limestone gets eroded but hard belemnites remain, making them very easy to find. We found around 25 belemnites during our 1 hour hunt there as well as a shell imprint and a mystery fossil. Like the previous location, the patch of limestone where these belemnite can be found is also only around 70 meter long, but luckily very rich.
  2. I am enjoying learning about the rocks in our yard. I found one that had something embedded in it, so I decided to try to remove the items from the matrix. I brushed and cleaned it well with vinegar and water and then used dental tools to pick the matrix away from it. How fascinating it was to see the matrix fall away - it was NOTHING like I expected it to be! There were two items embedded - and they may have originally been one whole piece. It is hollow and I have no clue if it is a fossil of some sort or a different type of rock that was embedded into a limestone rock. It took hours to remove these two items, but it was worth it. I did take some photographs along the way, but unless anyone is interested in seeing those, I will just post the end result. These two photos are of the first piece to be removed. This first piece is not deep - it seemed like maybe a "top" to the other piece, although they were laying side by side in the limestone. I have photographed both sides. Measurements are about 1.5 cm x 2cm. Thanks! Ramona
  3. My grandson and I found this chunk of fossiliferous limestone in our yard today and I cleaned it with vinegar, but it is very crumbly. I can tell that it contains mostly fenestellan bryzoa and crinoids, which is what we find most of in our yard. What is the best way to preserve this fossil to keep it from crumbling? I am hesitant to clean it anymore due to the fragility of it! Thanks! Ramona
  4. Antiquatonia maybe? (Brachiopod)

    I think this is the genus Antiquatonia, but I’m looking for some confirmation. I found this back in April, going through my finds and trying to ID. Found in Limestone. Glenshaw Formation (Conemaugh Group)
  5. Unidentified crystalized Brachiopod

    Hi everyone! A few months ago I recieved this little brachiopod with crystalization on the inside, it was a nice piece which came very cheap. Unfortunatly there was no information on this piece, no ID, no location and no age. All I know is that it came from an old collection and that the previous owner had lot's of fossils from Scandinavia & Germany. The matrix in very soft limestone, comparable to the Maastrichtian limestone from my region, I know similar limestone formations can be found in the UK, France, Denmark & Germany, to name a few. So I was wondering whether anyone can give more information on this piece, I know it's hard to ID something when no information is available, but maybe someone has a piece similar to this or knows the species when he sees it? Thanks in advance!
  6. Limestone Mystery

    I'm working on my fossil limestone sink and there are a handful of fossils showing up in the polished bowl. Most are horn corals or shells, but this particular one caught my eye. It might just be a shell or something, but I figured I'd let trained eyes give it a shot. It's about 1inch long.
  7. taking a rock (fossil?!) apart

    I have been watching Youtube videos about cleaning fossils and have learned quite a bit. Since I have SO many rocks in my yard I decided to kind of take one apart and learn about it. I originally thought this was some sort of coral/sponge fossil, but now I am not so sure. It has been thoroughly cleaned with vinegar and then I started removing what I think is the "matrix" with a dental pick. It's okay if I damage this - I am doing it so I can learn! I basically dug out any soft areas and have been surprised at what is emerging. In fact, I am not so sure it is a fossil at this point? Question: Will a fossil be damaged by scratching matrix out from around it? How can you tell what is matrix and what is fossil if you aren't completely sure what the fossil is? And I mostly have fossiliferous limestone, which is hard/impossible to remove all of the matrix from (this rock is not fossiliferous, but I have a lot of them laying around!)? All input appreciated! Thanks Ramona
  8. Petalodous Teeth

    To date, I've found 4 teeth, all in the same general area. One is shallow, the others are a big longer. The 3rd is a bit broken, I don't think I have a photo online right now of it. All are attached firmly to the limestone and I don't have any hope of ever getting them out clean. 1st Tooth: 2nd Tooth: 3rd Tooth No photos of this one. Sorry I promised 4 teeth, sadly only photos of three. 4th Tooth:
  9. What is this?!

    I've got to stop picking up rocks when I take the dog out... I already have so many in the house that I need to clean and study more, but I went and did it again today. It looked interesting, but now I am baffled. I cleaned this just a little bit with a weak vinegar solution and then looked at it. I am used to seeing fenestellan bryozoan, so these little round things caught me off guard. Are they branches of the bryozoan fossils? I I do seem some fenestellan bryozoan elsewhere on the rock, I think, but these little things look like eggs or snails? Point me in a direction and I will go research - again?! Thanks so much for being patient with me and my neverending questions! Ramona
  10. I think I have completed my first full cleaning of a fossiliferous limestone rock. I will post a series of macro photos of the rock here and would welcome input. I am new at this (like I said, it is my FIRST full cleaning) so would appreciate input and suggestions. I first soaked the rock in a vinegar and water solution for a couple of days, taking it out every once in a while and brushing it with a soft bristled paint brush. I had ordered some essence of vinegar to have a stronger acid, so when that arrived I used a very small amount of it on the brush to continue cleaning the rock. I then placed it in a baking soda and water solution overnight, again brushing and rinsing it every once in a while. It seemed to have stop bubbling this morning, so I declared it "done", but would like thoughts on whether it looks completely cleaned or not. I mostly see fenestella bryozoan fossils in it, in different stages and at different angles, so please let me know what else, if anything, you see in this rock. The size of the rock is as follows: 5cm long, 3 cm wide, 2.5 cm tall and I found it in our yard in Huntsville, Alabama. I am posting a number of macro photographs of different areas of the rock and I may ask questions on some of them. Thanks for any and all input!
  11. I though maybe the invert folks would get a kick out of these two limestone slabs. I picked them up several years ago when driving home from Kentucky along the AA highway. I cleaned them up a bit, but with the soda rig that @Gizmo loaned me. I don't really know what the critters are, but they look neat.
  12. Carboniferous Limestone

    This piece of limestone looked like sea shells (clams or brachiopods) at first glance. However it’s one bumpy continuous surface. Any idea? The rock would be around 305 million years old. The rock broke easily along this surface which made it easy to see. Shells typically show white preserved Agagonite on them as well. No such preservation on this surface. Rock from Western Pennsylvania, United States. The surface is wet. Ruler is in inches.
  13. Limestone polishing

    I’ve been collecting for a year now. I started to make a limestone sink, because I love the limestone that I find marine fossils in locally. Well part of the process was polishing the bowl I cut out, and wow, polished black limestone is a thing of beauty. It even has some fossils in it. I’ll post the sink one day. Naturally, I wanted to try polishing a fossil focus piece. I found this nice coral, likely Rugosa. I polished it to 3,000 grit with a Dewalt polisher and a set of stone polish pads. It was a quick experiment but I liked how it turned out.
  14. Triassic fossil

    Need help identifying the following fossil. Found this fragment in the limestone in the locality Theokafta of the Argolis Peninsula, near the Ancient Theatre of Epidaurus (Greece, eastern Peloponnesus). The limestone contains condensed ammonoid beds of the Hallstatt facies (Triassic: Anisian–Ladinian). The size of the fragment is about 1,5 cm. Any suggestion would be much appreciated!
  15. Ear Protection for Fossil Hunting?

    I know that eye protection, padded gloves for hammering to reduce harmful vibrations, and many other safety measures have been oft repeated on this forum to guard against injury, but I haven't seen much about ear protection specifically in regards to fossil hunting. First, an unnecessary backstory: I recently came to the realization that I have tinnitus and, being a bit of a hypochondriac, got myself freaked out over it. But that is, of course, silly since I can remember having tinnitus for years but just not really thinking about it. After calming down and realizing that I have had it for years, that it's very minimal tinnitus, and that it's not as bad as cancer, I have been considering ways that I can avoid making it any worse. Along with wearing earmuffs while vacuuming, I have begun to look for other strategies to avoid hearing damage. Now, some of these may be stupid questions (don't let anyone tell you, "there is no such thing as a stupid question."), but here it goes. The formation in which I hunt the most is the limestone/chalk Atco formation. One of my main means of finding fossils is just whacking on chunks of chalk, hoping to luck into some ammonites, echinoids, fish, or a perfectly articulated pterosaur clasping a new species of cretaceous mammal in its talons, and I have had much success (maybe not the last part). I mostly use an Estwing 4lb sledge and Stanely chisels with hand guards to do the job, but sometimes also use a 10 pound sledge for the harder and larger chunks. This works fine, but because I am dealing with relatively hard matrix the pinging of the sledge against the chisels can get annoying, but could it over time also cause tinnitus and hearing damage? Since I have gotten ear protection aware I have begun wearing EP3 Sonic Defenders when fossil hunting which have the great feature of allowing sounds like normal conversation and ambient noise in while reducing any noises above 85dB when the caps are off and greatly reducing all noise when the caps are in. Some of their other plugs like the EP4 and EP7 do the same thing and have more protection with the caps in, so I might get one of those too. So, my questions are: 1-When is it appropriate to wear ear protection while fossil hunting? 2-Could the pinging of my hammer against the chisel and/or chalk chunks cause hearing damage and thus tinnitus over time? 3-What kind of hearing protection do you recommend? Is what I am using ok? BONUS QUESTION-Any recommendations for padded gloves to get?
  16. Wormholes? Or bryozoan tubes?

    It's me again! And I promise that this is NOT a piece of concrete! ;-) (Joke from previous post.) This is the bottom of a limestone rock that has a lot of bryozoan fossils in it, found in our yard in Huntsville, AL. Do the holes look like trace wormholes? Or could they be from the digestive systems of the fenestalla bryozoans? I can get a closer photo tomorrow, plus photos of the rest of the rock if that would help. I left this one in the yard, but I know where it is! Thanks! Ramona
  17. I haven't posted in a while, due to traveling and then starting a new job, but I find it hard to stay away from the rocks in our yard. We recently moved into a house (Huntsville, AL), where I soon discovered that we had a wooded area with a creek bed full of fossils. From what I have seen so far they are mostly common bryzoan, crinoid, etc fossils in what I have learned is fossiliferous limestone (mostly). I ventured out today and photographed some rocks, as there are simply WAY more than I can bring into the house to study. I am wondering about this rock... According to what I have learned here, it is likely limestone with fenestella bryzoan and crinoid fossils? Oh, and the hitchhiker looks like some sort of insect. LOL It's well camouflaged, so you might have to zoom in to see it. If I am correct on this identification, the thanks goes to you guys! Ramona
  18. Is it a fossil??

    Hi guys, Today I was going trough some old boxes of not very well preserved fossils and I stumbled upon this rock which i found before a few years in a limestone deposit on a fossil beach here in Bulgaria. (Echinoids and ammonites are common for this site). When I found it I thought it really resembled a fish spine, so I took it just in case it really was a fish spine (although I doubted it). So can anybody tell me if this is really a fossil of some sort or is it just some natural rock markings. Best regards to everybody!!

  20. Found this chunk of limestone at my Lake Michigan's sand depleted "beach". Due to the extremely high water level, storms have washed away pretty much all the sand at this beach, exposing the large underlying rocks. What do you think of the almond-shaped preservation of the interior parts, while most of the shells themselves have been dissolved away?
  21. Help identifying poss fossil..coral? Texas

    My boss has a collection of fossils picked out of the Brazos river, TX. Most of his are pet wood/plant but this one perked my interest.
  22. I am trying to wrap my head around what these things looked like in "real life" so I can recognize them better. This is a limestone rock with what I think are fenestella bryozoan fossils, found in Huntsville, AL. Mississipian age. This photo is looking down at what I call the "top" of the rock. The next photo will be from the side, looking at the same area but from the "inside" of the rock. Can anyone point me to a site where I might find a diagram of these to better help me understand what they looked like? Thanks! Ramona
  23. This is my first post in the Fossil ID section - I am SO excited to find this resource! A have found a few very helpful folks in other places, but this group is a huge wealth of information! A bit of background - we moved into a house just outside of the city limits of Huntsville, AL, a couple of months ago. After finding a couple of fossils laying around in the yard, I decided to investigate the wooded area at the back of our property a bit more. Whoa!!! There is a creek bed on the property and the closer you walk to the creek the more rocks you have to walk over. Every single rock I picked up had some kind of fossil in it. The sides of the creek have rocks embedded in them, too. It seems like someone may have looked around a bit in the past (found a small pile of rocks) but many (MANY) of these rocks are in their natural state. Most of them, in fact. It seems overwhelming to me, but I have been delving into understanding the treasures I am finding. I don't understand all of the classification systems, but I found a place online that seems to indicate that we are in the Mississipian Age? The rocks which have been identified so far are all limestone, so I am assuming this one is limestone as well. The soil is VERY red (someone called it ochre red?) and some of it always remains on the rocks after I clean them. The fossils that have been identified so far are fenestella, bryzoan, crinoid. And I think the word fossiliferous was also used? I am a photographer by trade and macro photography is my FAVORITE, so I will post plenty of photos. This particular rock is a very small one compared to most of them. It is also harder than the other ones I have worked with - less "crumbly". The first couple of photos are of the top and the bottom of the rock, to get a general idea of the size and shape of it. The rest of the images are close ups of various areas. Any and all input is appreciated! Is it common to find an area like this where rocks such as this one are very abundant? From what I can tell these are all common fossils, but a great springboard for learning! Hints on how to clean and store the rocks appreciated, too, since there are so very many of them? Thanks!! Ramona

  25. Ammonites from Nigeria!

    Hi, everyone! Recently I got some ammonites from Nigeria, but I can not found any reference. So I have no idea how many species of them, I need your help!
