  1. Polishing Fossiliferous Stones

    I have found a number of fossiliferous paleozoic stones of various sizes, types, and quality, in a cretaceous conglomerate layer. I have included a picture of some of them. I rather like them because, although the fossils are not very high quality, it is neat to think about how they have been fossilized and eroded out multiple times. I was thinking about running them through a rock tumbler to polish them, but I am concerned that the hardness of the fossils compared to the rock might present some sort of issue. Does anyone have any thoughts on why this may or may not work?
  2. Prognathodon Tooth from Morocco

    From the album My Fossils

    I found this tooth from Morocco I’m a shop in Portugal. While the root could be faked in someway. The actual tooth, is real. I did a post on this before but I took much clearer images for the ID for this later on. I decided to repost with these images.
  3. Hello fellow creek crawlers and rock hounders! I am not dead LOL! After a 3 year hiatus I am happy to be back here on the first forum I have everjoined posting my secret guilty pleasures which are of course...fossils. Sothe reason I am back is I finally found a peer here in Texas who is aBiologist with a huge love for paleontology to go on trips with (rememberI'm from Indiana) and we have always wanted to go to the North SulphurRiver in the middle of Texas winter, arguably the best season for fossilinghere! No venomous snakes out and no bugs. So we made an impromptu trip from Princeton to Ladonia on the tenth becausemy friend and I were craving an adventure for a chance to find mosasaurbones. I was so surprised it now takes literally 1 hour to get there versusabout 8 years ago, when I first moved here, I swore google maps said ittook almost 3 hours! I was so happy to read that and we arrived there inwhat felt like only a 20 minute drive. No fast food places or Walmarts onthe way, just really old towns lost in time and country fields. Afteralmost a decade of wanting to see this place I finally saw the river! The stairs absolutely killed me, let me tell ya! I'm in my late 20's andpretty active but those stairs made my legs and knees so sore I had to crawl upand down them and days later still in pain. Each step is nearly half ameter tall and there are no rail guards on top of it being muddy andslippery. It was far easier to use the mess wire to climb up and down thecliff bank. I'm glad I decided not to bring my family with me because I can't imagine them trying to go down the stairs, it was so hard to get down even for 3 adults! Look at this cool ammonite impression in the shale! It was too crumbly andwet to extract so we just left them because they would break. We decided to stay near the bridge in case of rain and hugged the exposedsilt beds and gravel bars in the middle. We knew it was probably over-pickedbut I had hope. I tried to stay close to the "red zones" instead of themuddy shale. So we didn't go far from the stairs, just under the bridge inthe pictures. The river was super low in fact there was little water butanything wet was near freezing temperature. We got stuck in the mud and Ieven had no choice but to walk through the ice water to retrieve my shoesLOL next time I'm bringing the high wader rubber boots because it was the worsthaving near freezing wet socks for hours. I was stupid and didn't bring mysieve or trowel so we picked from on top. Honestly I really didn't knowwhat to look for except for black bone and baculite pieces as I have noexperience with the Ozan formation or shale. I'm used to picking for sharkteeth in gravel at Post Oak creek up in Sherman, Texas orcoral/ brachiopods in limestone or silica in Indiana. Everything here wasdifferent colors in the dirt and it was overwhelming but useful. I had thisinstinct to stick to the gravel beds in the middle (where I found all of myfinds!) although I was interested in the exposed red walls of the riverbank. I was wondering if a sieve and geologist hammer would be a good ideaand have a go at the walls next time we visit. Any pointers where to lookfor next time would be kindly appreciated! Omanyte with an ammonite aka Helix Fossil Moving onto my finds!My colleague found these massive baculites, some pretty black internalmoulds of shells, and shark teeth. My finds! I think I did okay for a picked over location at theentrance and no sieve. We only stayed for maybe two hours at most andagain I had no idea what to look for. I need help with some IDs! I have 7pieces of bone I am interested in, they look like marine reptile boneswhich is exciting! I'm sorry if my pictures are bad or need resized! I haven't been on a forum in years and I forget how to do everything. I am also uploading from my phone so I might have to edit photo or text spacing later. G. Please tell me this is something cool! I'm hoping this is a sea turtle shell piece with tooth marks on it! WTH is this......? Here is what I think they are.... A. Mosasaur "wrist" bone?B. Mosasaur or other marine reptile "finger" phalanges boneC. Mosasaur or other marine reptile "finger" phalanges boneD. marine reptile bone- possible tooth?E. unidentified marine reptile boneF. Marine reptile bone? (one of the curved bones near the eye socket?)G. Cretaceous sea turtle shell fragment!? (Has predator tooth marks!)H. ??? marine reptile tail bone piece? I. Fish vert J. Fish or small marine reptile vert K.Leptostyrax tooth L. Squali tooth M. Arrowhead Fragment N.??? Internal mould of a tree branch? It has a branching structure but it doesn't look like coral to me O. Corprolite? P.??? Help me with this one! Is it a rudist? Q. Baculites baculites baculites. R. Fossilized mouse incisor (recent) S. Cretaceous tube worms? They were everywhere to I stopped picking them up. T. ??? Coral? U. Petrified Wood V. Ammonite impression on shale W. internal snail shell mould X. Plicatula shell? Overall I loved the whole experience and when it warms up a little bit I will definitely head back out here! This is my new favorite fossil spot I have ever been to! I love the Cretaceous life fossils and the arrowheads found here are also very nice. Even if you don't like fossils there are neat stones, artifacts, and animals to find! Things I learned to help others plan a trip here: -The "Fossil Park" entrance to the river in Ladonia, Texas is the best place to park since it's FREE and open 24 hours/all days of the year. - Come here in Winter so there aren't any snakes or bugs -Make sure to bring your own food and water bottles as there are NO restaurants or stores nearby for 13 miles. Also bring TP in case you need to "go" in the woods. - IT WILL BE MUDDY! Bring an extra pair of clothes, shoes, socks, towels, etc if you plan on staying the day there. WEAR RUBBER BOOTS! I ruined my running shoes completely and had to fish them out of mud. I recondmend steel toe high-wader boots, after this trip I went to walmart and got a pair of tight fitting 16" wader boots for only $20 to use for next time! Also helps protect your legs from bugs, briar, snake bites, etc. - If you are like me and kneel in dirt or lay on gravel looking for fossils on the top exposed earth- bring some knee pads! - The stairs are very steep and will make you sore so be sure to do stretches and go down slowly -Use a long walking stick to test which parts of the river you can walk on. Example is that there are areas of one inch water you can walk across, but be careful as its tricky! Sometimes the shale is solid rock and other areas where it is just straight-up mud inches down and you will sink. - I recommend bringing a sieve and trowel! -Bring first aid kit and medicines like epipen if you have bee allergies. I also brought asprin, allergy pills, tums, etc. -There are wild pigs in this area, I saw boar or even javelina (not actually a pig) foot prints in the mud! -There are arrowheads, beads, and mammal fossils here! Not just marine Cretaceous fossils! Bring a backpack or container for your cool finds. - Do not go here if there is rain in the forecast or if it has recently rained a lot. The river cliff banks look like they could easily make mudslides and the river may fill up fast. -Don't go alone! Safety in numbers! I still can't decide if this is a good place to bring children or not, personally I wouldn't, but if you are an adult at least take another adult with you! There is no hospital nearby and I had poor cell phone service. You will need to fend for yourself with wild animal encounters and the geology here. It is very steep and muddy. In case of wild animals (wild pigs specifically) if you don't have a gun at least bring something to scare off animals and defend yourself with. I brought bear mace, airhorns, flares, and a hunting knife just in case. You will probably never use them but better safe and prepared!
  4. today i have found another inclusion from my raw lot of cretaceous NJ amber. it bears resemblance to a stellate fern hair (comparison picture shown below) and also to stellate fern hairs I have found in a piece of (presumably baltic or dominican) amber that is 30 MYO. i'm not sure about this and i was wondering if anyone could shed some light on it, have these been documented in NJ amber before? (probably) anyway, here are the pictures: the fossil in NJ amber i found---> comparison picture of another stellate fern hair i found this one on the internet---> another stellate fern hair i found in 30 MYO amber (probably baltic, maybe dominican) -->
  5. As monthes passed in 2017, i wasnt under the impression the year was that good fossilwise. But now it's over and after rewieing what i found during my different trips, i must say it has been a hell of a year. So here come most of my 2017 best finds. This is a trip in some french hunting place, mostly nothern half, From west to east, from ordovician to cretaceous. I hope you will enjoy the diversity
  6. Shark tooth

    From the album In-Situ Shots(various locations)

    1-12-18 Denton County, TX
  7. At the start of the Christmas holiday I went with my girlfriend on a fossil hunting weekend to the French coast. first stop was the “pointe au oies” with jurassic deposits. apart from a small echinoid we didn't find a lot of decent fossils. after lunch we went 80km more to the south to a little hotel above the cretaceous cliffs near Ault. Since it was still light when we got there we made a 1st prospection on the beach and quickly found a few nice echinoids ( Micraster sp. ) the next day further inspection of the boulders on the beach delivered even more beautiful echinoid specimens. most of them very well preserved. This was a successful trip, I’ll certainly go back there next year.
  8. Cretaceous Horn Coral, Cen Tex

    I recently found these horn corals in a road cut near Gatesville TX. I am not as familiar with Cretaceous stuff so thought yall could help me ID. Thanks
  9. nj cretaceous tooth id

    finally got out with the wifey today at some different streams with the weather not so bad and streams frozen and found a hand full nice teeth in the first pic.......................I'm assuming the second pic is a broken worn enchodus jaw/fang if someone can confirm and also the balance of pics if someone can confirm (although) broken in half if this is reptile of fish tooth,,,,thanks

  12. Very tiny dinosaur tooth

    I was sorting some North Carolina Cretaceous matrix this week when I saw a shape that reminded me of a Theropod tooth. I really didn't think it was because of the tiny size but when I stuck it under the microscope I saw a few serrations on the distal side. Now I'm convinced it is a Theropod tooth. I've looked up some Cretaceous lizards (Teiids and Varanids) but their teeth are different but varanids can be somewhat similar. The matrix is from a late Campanian lag deposit and most of the fossils in it are heavily abraded. This is the first theropod tooth I've found. No sign of serrations on the mesial side but they could have been worn off if they ever existed. I tried a crude count of serrations by extrapolating the number of serrations per millimeter. The count is somewhere around 8 serrations per millimeter.
  13. Latest Lake Waco Trip

    So yesterday I hit the Waco Pit since it had been a couple of months since I last got out. Previous two trips were great since all I found were shark teeth. On one trip I found nine teeth in about 1 1/2 hours. Yesterday was just a chance to get outside and away from people. My other option was to go cycling on the river walk in town. Yesterday was pretty cool, temp was 47 degrees when I arrived. There was a cold breeze coming from the south. Skies were very overcast as well. Typical Central Texas weather. I hit the trail head and decided to head east inside of my normal west route. I have searched the east side a little before in the past. It's not as abundant with fossils like the other direction is but I have had some good luck finding things unusual. For instance my first summer there I found a nice rock with a Hemiaster Calvini in it. Upon getting home and cleaning away the matrix I found not one echnoid but three. So this time I wasn't expecting much. Pretty soon I found what looks like a piece of crab claw. I put that away for later. Then I find two shark teeth a few feet part. Not squalicorax but I'll take it. Finally I reach the embankments that are fun to get to and usually have tons of shells there. I find a couple of hash plates that look nice. They would both look great on a desk if I had a desk. One had a cute little echnoid spine in it. Then... I see a grey thing in the soil with spikes. At first I thought it was leaf but no this was solid. I took a few pictures of it in situ before prying it out of the ground. It looked like a horseshoe crab but I have never heard of one being found here. I looked it over several times, broke away some matrix and yes that is what it looks like. I carefully put it away in a container so I get a better look at it at home. I continue on searching for a bit. I spent a couple of hours there before heading home. At least it was a fun trip and there wasn't anyone there. I can be really anti-social at times. I get home and place the fossils in a bowl with water. After awhile I start brushing them off. What I thought was a cool looking horseshoe crab ended up being a piece of a very large Mariella piece. I'm not an expert in determining how big something is from a smaller piece but I guesstimate it could be 24 inches circumference. I'll include more pictures if it will let me.
  14. New Jersey Cretaceous Vert. ID

    I was reading a description of Mosasaur material that made me re-think a vertabrae I considered to be Mosasaur. It is from Monmouth County NJ (Cretaceous) and does have a cone shape so I was wondering what exactly it is. On njfossils.net it gave this description (below) of Halisaurs so I was wondering if it could be this or even croc. Any help is appreciated. -Frank "The rare species, Halisaurus, has vertebrae that are distinguishable by the conical shape of the vertebrae. The main difference is that they are tapered toward the convexed end of the centrum and lack the divot of "crocodile" vertebrae."
  15. I went to the Waco Research Area a few days ago and found my first shark tooth and some nice ammonites. I know nothing about shark teeth, any ideas on this one?

  20. Ceratides

    HI I went to my favorite fossil hunting area (Sulaiy formation\Berriasian \ cretaceous of Saudi Arabia) and found this fossils . I hope you help me in identifying this fossil is it Ceratides sp or other types . It is large 15 cm wide and 10 cm high
  21. I was in a local Barnes & Noble last week and was happily shocked to see that a second edition of "Oceans of Kansas" had been released (came out in September). The first one (Everhart, 2006) was a great surprise in its own right. If it had been just a faunal review of the various layers of the Niobrara Chalk, it would have been interesting enough but it covered even more oceans than that. A seaway covered much of Kansas over much of the Cretaceous but it wasn't the same cast of characters from beginning to end. Various organisms evolved, co-existed, and disappeared across that time and the book is an excellent guide to the fossils found and studied up to the mid-2000's. The second edition looks to be a must-have as well. http://www.iupress.indiana.edu/product_info.php?products_id=808653 It's the only thing on my list to Santa. Jess
  22. anomotodon?

    Here is another from the neuse river in NC. Eocene and cretaceous material found there. Scale is mm. How did I do on my guess? Thanks
  23. When I was preparing my previous entry on nodosariid forams from the Pecan Gap Chalk, I originally included a specimen that I had identified as a member of the genus Dentalina. This identification was incorrect, and I edited the entry to remove that specimen. Here it is again, with what I hope is the correct identification! The genus Strictocostella is a member of the family Stilostomellidae, and this species is illustrated in Frizzell's "Handbook of Cretaceous Foraminifera of Texas" as a member of the genus Stilostomella. He also listed it as occurring in the Pecan Gap Chalk. Better images can be found on the World Foraminifera Database -- they show specimens with some very small spines around the bases of each chamber, almost what one might call "hispid". The drawing in Frizzell does not show this feature, nor does my specimen. I have not yet looked at Cushman's original description, but I am reasonably confident that this difference is within the range of natural variation. (I have seen this kind of variation on images of other stilostomellids.) I like it when I "Live and Learn!" And I'm glad that I caught the error.............
  24. My name is Gary L Thompson I am the sole discover of the Mosasaur Prognathadon stadtmani that currently resides at BYU, This specimen was found in Cedaredge, Colorado in 1975. It took over 40 years to get the complete casting of this mosasaur. I thought maybe this might be a story of interest for you since this is an extremely rare fossilized specimen from about 85 million years ago and the fossilized marine reptile is the only one ever found on the western side of the prehistoric sea that once covered an area ranging from Utah to Kansas and Nebraska. It was a ferocious creature approximately 35 feet long. The excavated skull bones remain the property of Brigham Young University’s Paleontology Museum." I just wanted update every one on some misleading information regarding the find and to send the most current information updates. It appears that the Genus name is probably going to change to a brand new Genus, the scientific community is still discussing this one, will try to update when that happens. BYU has now completed the entire skeleton and now have it up as of the beginning of the year. I have included current photos of it along with "My true story" and all corresponding credits for the find, scientific research and preparation of the specimen. I just thought these might be of interest to you. The photos are from the BYU webpage. My true story finding a mosaster.docx Order of Contact and Credits.docx Original_aticle_1975.docx
  25. Hit the creek for a while. It has been hit pretty hard since the rains a week ago and the holiday traffic. Found the usual potpourri of pieces and parts and found four very worn Ptychodus right off the bat. Luck changes as I work my way up the gravel bar. Found several nice P. whipplei including the largest I have ever found just over an inch wide. Found a beautiful small P. mortoni and a sweet complete S. raphiodon. I also found what at first looked like a Ptychodus shard but when I got home and cleaned it up, I believe it is a small piece of coprolite. Weather couldn’t have been better. 60 degrees but creek was still frozen solid in shady areas. Had the place to myself the entire time. Still looking to add a couple new species to the collection. So far five down.
