Hi all! I just joined this forum and want to thank everyone upfront for such a great resource and community. My wife and I recently relocated to north texas from upstate new york. We fossil hunted up there and since we moved to texas have found some great specimens. It has been amazing having the opportunity to hunt new deposits! Last weekend we went to mineral wells and post oak creek...both places we found from reading this forum! I think a lot of what we found is quite common but definitely very different from what we are used to in New York. We found shark teeth, shells, corals and some stuff we cannot identify...We even found what looks like a piece of native american pottery (reddish square on right side. Thanks again for looking and let me know if you see anything interesting. We are eager to learn!

Hello, my name is Jake. I am a young major fossil collector and am new to the Fossil Forum. I live in Middletown Delaware and am wondering where I can find the dredge piles at St Georges on the C and D Canal. I have been to the dredge piles at the reedy point bridge before and found a junk load of belemnites. I found it really fun. But me and my mom are major shark tooth enthusiasts and we did not find any. I know that you can find them there but they are not as common at that spot. What I do know is that the dredge piles from the marshalltown formation contain much more shark and vertabre material. So me and my mom want to find those piles. I know that it is in the area around the summit bridge on the north side, but it is a big area and could not find the exact location. I met someone there who had found fossils there before and told me that they are around the soybean field but that area is huge and could not determine the exact location. I was wondering if anyone knows exactly where to find the dredge piles and if you could, please insert a marker of the exact location on a google maps image. Thank You!

Okay, for all my friends who asked how I breakdown the matrix and look at it, this is how I breakdown the Martin Marietta Cretaceous marl type matrix. The Matrix I work, is from Martin Marietta Cement Quarry 5-8 inch thick phosphate pebble layer. 1. It starts with placing about 20 pounds or fill 1/2 of a 5 gallon bucket with the raw matrix. 2. Then I add about 4 bottles of Hydrogen Peroxide, to cover the matrix completely. Let this set for at least 24 hours. Then, it will be broken apart enough to sift. 3. I Sift it 5 different sizes. 1/2", 1/4", 1/8", 1/16", and 1mm. What falls thru the 1mm sifter, I usually use a gold panning technique to remove the remaining dirt, as the phosphate (everything black fossilized) is heavier than the marl type matrix. 4. Once sifted, I allow it to dry in the sun. This seams to setup or harden the fossils somewhat. 5. After a complete drying, I place them in individual ziploc bags and write the location and what it is on the bag. These are stored for rainy days when I can't get to the field to hunt. 6. Now it's just looking thru it under magnification to find the fossils. I use a 2-180X AMScope inspection microscope with wide field of view.. I made my own tweezers to fit my hand.Took a pair of curved tweezers and filed down the tip to allow picking up finer materials, roughed up the grabbing side of the tip with a file, and added a shaped wooden handle to fit my hands. I find about 5 aprox. 1/2" fossils per 20 pounds of matrix. I find several hundred small to micro fossils as well.

Splitting some mud stone/ shale from Arundel f and found this little beast. Shale is a misnomer too. But it was a noticeably "layered" piece of float in the College Park area. it is small. The fibers are from a q-tip, so maybe 1/16 of an inch, or slightly larger. Hard to photograph because of the dark background. Added 2 from a different device.

https://www.fhsu.edu/news/2018/08/fossil-data,-images-from-sternberg-museum-now-available-online This is pretty cool. Sternberg museum is putting everything on-line. The search function is awesome. They still have a lot of stuff to get scanned, but everything is at least listed now. This can be a great tool.

I cant do any fossil hunting anymore, but i can still prep. My youngest son is a real fossil hunter go gitter. He finds lots of stuff like his father used to do. He worked on this and then called me and asked if I would help out. He has a ME9100 that I gave him and he knows that I have a Junior Jack. A Junior Jack will remove 10 times the rock the 9100 will do. wish I had a before photo, but afraid not. Took me about 7 hours to get this far. Lots and lots of rock to remove. The appature on this Placenticeras is not correct but it was shaped in order to remove rock to expose this male Hoploscaphites crassus? My son May have a before picture. If so, I will post it and then you will understand why ive done what ive done. This rock measures 12 inches. Kinda heavy too! RB

I have several shark teeth from Post Oak Creek in Grayson County, Texas and I was hoping to get help with identification. From what I've read it is the Cretaceous period. Here are some of them. Thank you in advance.

Ok, so I found this in the creek and being a newbie I didn't know what it was so I brought it home. I really thought it was like a rusty old drawer pull. That's the shape it had. I had my son split it and it seems like bone. I hate that I deleted the picture of it before we broke it, but I tried to put it back as best as I could to how it looked. Any ideas on what it is? Thank you.

[WARNING: A lengthy read, but hopefully enjoyable] Last summer Chuck @megaholic invited me to go out with his fossil friends to dive the Meg Ledges offshore from Carolina Beach, NC. We could not make it that year as we were several time zones and about 2700 miles to the west in Cascade, ID to see the total solar eclipse as it streaked across the US on August 21, 2017. (It was well worth the cost and effort to see this impressive astronomical event. This year Chuck tried again and I was happy to be able to take him up on his offer to join his group for some meg tooth dives. Initially, I started checking for airports nearby and started hunting for inexpensive airfares. Chuck quickly pointed out that it really isn’t that far of a drive from South Florida and that he usually covers the distance in one long day of driving. The idea of driving up to North Carolina sparked the concept of an epic roadtrip with several stops along the way bookending the diving portion in the middle. The six potential diving days of the charter were fixed at the last couple of days of July and the first few of August and so with that anchoring the middle of the trip, I was able to build out from that time to lay out a fun itinerary with lots of stops along the way. I’m pretty good at composing lengthy journeys and had fun mapping this one out. My wife Tammy has been planning her retirement for some time and though her employer was successful in tempting her back for longer than she had planned on working for them, she was finally at a good stopping point with her project wrapping up. She actually based her last work day before retirement on my finalized schedule. She had her farewell lunch and said her goodbyes and was back reasonably early on a Wednesday and we had the car packed up and were heading out just after the morning rush hour died down on the following Thursday. Our first port of call on this roadtrip was north-central Florida. I had a number of specimens that I wanted to drop off in person to the Florida Museum of Natural History (FLMNH) in Gainesville. Along the way I had made plans to visit the first of many TFF members on this trip. Harry @Harry Pristis is a great authority on the types of items we pull from the rivers and creeks here in Florida and anybody who has read any forum topics about these items has undoubtedly noticed Harry’s excellent photographs of his enviable fossil specimens which are invaluable in confirming IDs. Harry also has a wonderful collection of old bottles and that is also a bit of a side passion of mine (I like hunting for all sorts of things). Harry and his wife invited us in when we arrived and we were able to indulge in one of my other favorite hobbies—talking about things which interest me. After some wonderful conversation we got a chance to marvel at some of the spectacular fossils (and other items) in Harry’s display room. The walls were covered with all sorts of interesting bottles that drew my attention equally as much as the fossils we were soon to see. Harry (as you would expect) has his items very well ordered and cataloged so it is much more like visiting a museum than a personal collection (a concept that would be repeated throughout this trip). Harry stores his fossils in custom made cabinets with shallow drawers based on the type of cabinets that shell collectors like to use. The tops are inset with nice areas to highlight some pretty things under glass. Harry has collected for many years and as such has built up a terrific assortment of enviable fossils. It was quite a treat that could easily be summed-up as “like a kid in a candy store”. There were just too many wonderful things to see it was too easy to forget I was holding a camera. I asked Harry select a couple of his favorite items for a couple of example photos. He selected an odontocete mandible (Goniodelphis cf. G. hudsoni) from the Pliocene which was recovered from the phosphate mines (when it was still possible to access them). The other stunning piece was a rhino tooth from Teloceras cf. T. hicksi (also from the mines). Truly special items to be able to see up close and personal.

Found on the shoreline in shanklin on the Isle of Wight, UK. Local fossil hunter told me that whilst dinosaur bones are rare, marine reptiles are more common because of the shoreline geology. Found in lower greensand (Cretaceous) deposits. Photograph is difficult to capture the unusual shape - I really have very little clue as to what it could be, I'd be amazed if any detailed identification was possible but would be nice to find out what it vaguely is, even if it's absolutely nothing! The shape definitely strikes me as some kind of joint that has maybe been fractured a long time ago and weathered? Any input would be greatly appreciated!

Dipping my toes in 'bama's Cretaceous waters.
MeargleSchmeargl posted a topic in Fossil Hunting Trips
Armed with information courtesy of @FossilDAWG , I've headed to Montgomery, Alabama to get my first taste of Cretaceous fauna from 85-80 MYA (Santonian and Campanian stages). After booking a hotel in close proximity to the creek and (restlessly) sleeping the night away, We ate breakfast, got our boots on and eagerly drove to the site with the help of a GPS. When we arrived, the GPS signal was showing us miles off from where we actually were, so Google was shelved and Papa and I started the flurry of pictures. As per description, the entrance to the site itself was kind of jagged, made of huge concrete slabs left there from a time long forgotten. After we got down this man-made hill, I took a moment to take in the sight, the outcrop plainly in view: We slowly sloshed through the creek, being careful not to slip on rocks or step into deeper-than-you-think holes in the stream bed. Once we got to the outcrop on the far side, we got right to looking. Barely even 5 steps in, I instantly recognized the blade of a shark tooth that was sticking out of the sand. It has little root on it, though I can tell that it is probably a sand tiger. It is the only one I've found, so far. Venturing further in, we started finding Oysters. Lots of them. It wasn't long before we found what was apparently the main bed they came from: To sum it up; Bivalves. Bivalves everywhere. You almost can't walk there without stepping on pieces of them they're so abundant. With everything there, it didn't take very long to get a decent haul, with pieces of ammonites, two echinoids and a lone gastropod being added to the seemingly limitless supply of bivalves. I was quite tempted to get back in the creek and have another go at it, but Papa balked, citing the heat which was in the 90's, and since he was the driver he had all the decision-making power. I came away with 4 specific favourites, the gastropod, the 2 echies, and one particularly complete valve (the name of which eludes me, as I am by no means an expert in bivalves). The right-most echie's top side is covered in River crud, though as I found it practically in the water. Cleaning tips, anyone? Do keep posted, as I will make 3 return trips, when temps aren't in the 90's.

Earlier in the week I made a trip to Ramanessin Brook in Holmdel, NJ. I came back with a bunch of teeth and fragments, including these tiny things that I have clue what to think of. Any help is greatly appreciated. Please let me know if you need a different photo. #1 #2 #3 #4 #5 #6 #7

I found these sorting through some Aguja formation from West Texas, late Cretaceous, matrix. I am not sure if they are teeth or claws. I think that the middle tooth may be a croc, but not sure. The hash marks are 1mm. Any ideas?

Echinoid urchin spine is a complete guess. I don’t have a clue. Does anyone know what the tan thing with bumps is? It is just over 2 cm long so far. I found it in the Cretaceous, Grayson Formation in North Texas. It has Mariella brazoensis, Waconela wacoensis, a little nautilus, way too many oysters among other things in the conglomerate with it. Could it be an urchin spine? It has tiny, basically microscopic bumps all over it too. It still needs work uncovering. I came to the oyster on top of it and will have to take another approach to removing the oyster.
