You may or may not know that I have been obsessing over finding a mosasaur vertebra and tooth. I am lucky to live in Texas where fossils are plentiful in some areas but the most productive mosasaur area is still 6 hours drive from me. So I don't get there often and the few times I have.....no verts or teeth for me. I am not complaining (too much) because I have found other great things in the North Sulphur River, but not the mosie vert or tooth of my dreams. I am lucky to have friends who hunt there regularly who feel sorry for me and give me verts and even a lovely big tooth. But I DIDN'T FIND THEM. I do know that mosie stuff can be found in Central Texas where I live (thanks to @Jared C and his amazing adventures) I know they can be found (although very rarely) in our local creeks and such. So of course I keep an eye out while hunting but with no real hope of finding them. But I hope anyways! Which brings me to today....which I count as part of my birthday weekend (birthday was Friday, but you know.....weekend still counts! ). Went out on a little fossil hunt to a new site that a friend told me about...lots of baculites (which are relatively rare here in Central Texas) and lo and behold.....I FOUND MY VERT! And not two feet away....a little tooth! Mother Nature decided to gift me not just one, but TWO of my bucket list fossil finds today! Granted, they are pretty busted up and the tooth is not complete, but WHO CARES! I FOUND A MOSASAUR VERT AND TOOTH practically in my own backyard!!!! Turns out this little exposure is Ozan Formation and I can't wait to get back out there again....after a good rain! And, to top it off, found a complete ammonite in addition to some lovely gastropods and about a billion baculites. It's no mosie in situ, but I'll take what I am gifted. Thank you Mother Nature!!!

Fossils labeled as from East Bluff, California but not so sure if that’s correct
Guest posted a topic in Fossil ID
These were sold to me stating they came from the East Bluff area in Newport Beach, California. But research into fossils from that area comes up with late Pliocene material that doesn’t look anything like these. The serrated tooth is especially confusing. Any ideas?

Found this tooth in my Aguja Formation micro matrix. It's about 6mm in length. I know it's in really rough shape, and I actually broke it in half attempting to get pictures of the distal/mesial sides. Can anyone give me an idea of what it may be? Could it be a theropod tooth? I don't see any evidence of serrations on either side. Sorry if the pictures are not the best. It was extremely difficult to take pictures, especially after it broke in half. Base of tooth Distal Mesial

Hey all, Looking for input from all the wonderful people I've called upon in the past! I found this tooth in 2022 sifting at GMR. Upon first glance I thought it to be a small dolphin tooth but after digging it out of my collection recently I put it under a higher power magnifier and actually looked at it with attention. I'm starting to believe this maybe a mammal tooth or canine specifically. I've been to GMR many times and have found a distal bone of a mammoth and a hoof bone of an ancient peccary which was identified by the curator of prehistoric animals at the Indianapolis State Museum. Any thoughts on this would be appreciated so I can try to file and put away for safe keeping! Thanks all! Steve

Hi, Any ideas as to what this kind of fossils either of these are ? They are from near Sites, California. I'm not quite sure the age, but based on the age of mudstones in the area, it should be late Jurassic to Cretaceous. Note this is form a bore hole (not surface collected), but I am not positive of depth. Thank you in advance.

Hello all. I was hoping for additional insights on what this may be as well. I know this is a vertebrate bone of Cretaceous age found near block mountain outside of Dillon Montana during a classical mapping trip. On one side of the specimen there is a prominent yet thin plate of bone with a robust ridge along one margin. On the opposite side of the specimen is a rectangular structure which may be a scute or possibly another type of mineralized structure. Any insights are appreciated.

we got a greaaaaaaaaaaaaaat fossil some time ago from a supergreat US-Seller. This was found in Hell Creek, part of THE KING It is necessary to do a little more prepwork on it, but, I have to remove this brown, harder matrix. What is it? Phosphorite? Shells? Or bone? I am not familiar with the Hell Creek Matrix, more with some of the lovely fossils Thanks for supporting! (e.g. what you see on the pics is around 2 x 2 inch), one pic is from the top, one from the bottom, but I would assume this are different whatever, not two views on one thing from two sides

I was fossil hunting in a new location in north Tarrant County, Texas and found what I believe to be my first fossilized bone. It was at a gravely creek shore in the Grayson/Mainstreet Limestone formation (undivided) near the transition to Woodbine. I found plenty of fossil oysters and a couple of Turrilites ammonite fragments I expected to find in that formation. But I found this bone completely loose at the edge of the water. It's got a bit more weight and isn't as soft or fragile as modern bone. Though the internal bone structure appears to still be mostly hollow. I would like to know if it is in fact a fossil, what type of bone is it, and potentially what animal it came from. I'll be taking to the Dallas Paleo Society meeting next month to see what they think.

Oklahoma 2 After heavy rains arrived the afternoon of my first day fossil hunting, I headed further south and west in hopes of better weather conditions on day two. My decision was to overnight in Waurika and then check out a Lower Permian site in the area. To my surprise, no motel or restaurant existed in town, so I had to backtrack 40 miles to satisfy my belly and find a place to sleep. Not a good start. In the morning, I headed to a popular easy pickings spot to spend the morning at. What I encountered was a water saturated landscape. Quicksand mud was everywhere after the rains of yesterday. In addition to the problematic mud, the terrain was interspersed with rough rugged reddish Mars like rocks. I made it out to the exposure, only to be disappointed that finds were almost nonexistent. A little Malachite and a few possible fossils were all I could find in areas able to be traversed by foot. Those that suggested me to be on my hands and knees will be disappointed that I did not follow their advice due to the mud. 1. This was the typical red rock I mentioned. At least some had Malachite attached. 2. Possible plant fossil, and a strong suspicion its from Lepidodendron. 3. Finally, these specimens take on the look of a bivalve and the donut-shaped piece could be a vertebra from Archeria, a Permian amphibian The afternoon would be spent further east along the north shore of Lake Texoma. On the way, I stopped at a small roadcut and collected these fossils. The formation seems similar but a little different than what I saw at the lake. These are the finds from the roadcut. Does anyone have a guess as to the formation these came from? 4. 5.Texigryphaea 6.Texigryphaea 7. 8. 9. 10. Some angles look like turrilites but then another angle looks more like turritella After that short stop, it was off to the lake. Research at home showed a suggested public access road down to the lake. In reality, it was gated off and signage for trespassers to be prosecuted. As I turned around in disappointment, a gentleman was walking on the road. I stopped and asked if my directions to this site were correct. He verified it was but then told me of public land close by that if I didn’t mind a long walk, would take me to my desired location. I took his suggestion and after a vigorous downhill walk, arrived at the lakeshore. Water levels were low, exposing quite a bit of rocky shoreline. Oyster, bivalves and ammonites were everywhere. Unfortunately the nice ammonites were too large to drag back up the hill, let alone fit in my suitcase for the trip home. So representative pieces were collected as a remembrance of the area. Once home, I felt these specimens fit the Cretaceous Duck Creek Formation. 1. 2.Texigryphaea 3. 4. Plicatula. 5. 6. 7. This specimen is likely rock, but mimics a fossil enough to let those familiar with the area give their thoughts. 8. 9. A smooth large ammonite. Are those oyster attachments on its one side? 10. 11. The only small ammonite found, a tiny Mortoniceras. 12. 13. Smooth ammonite 14. This is the largest chunk of ammonite collected. I stumbled on another complete Eopachydiscus that appeared to be 2.5 to 3 feet across laying on the beach appearing to have been prepped out. It took all my might to even flip it over to examine the other side. My suspicion is that the owner of this ammonite ran out of steam and decided to just leave it on the beach. I also left it for someone stronger than I.

Ever since seeing @sharko69's Monster Texas Cretodus, I've dreamed of owning a very large Cretodus tooth. Well, now I have one, and at 6 3/8" on the slant, I believe it to be world-record sized. (I sculpted this using epoxy putty and colored it with acrylic paint.) The top row below is the tooth prior to painting. Here's an in situ shot.

This is a re-submission of my post from Thursday, Feb. 15, 2024 with the addition of a short video of the specimen. The photos just didn't make as much sense since it was hard to follow orientation. The bone was a surface find in northwestern New Mexico and is about 5 inches wide, and 3-1/2 inches tall. 20240216_133319.mp4

Shown below is a tooth, identified by the seller as that of a Squalicorax pristodontus, from the Demopolis Chalk. However, given the shape of the tooth, I wondered whether it could have instead come from a Squalicorax kaupi. I've tried altering the saturation and contrast on the image to make the tooth clearer, but I fear it hasn't done much. Come to think of it I should probably also have included a scale and an image of the other side of the tooth. The tooth is 1.2 centimetres wide and 1.3 centimetres tall. Should an image of the other side of the tooth prove necessary, I'll upload one. Thanks in advance for any suggestions Othniel

Hi everyone! I was going through a batch of Spinos I got recently and this one stood out. It measures just over 4.5 cm and appears to have a second carina on one side. It reminds me of those really rare pathological therapod teeth I've seen with parallel sets of serrations except it's Spino so the serrations are.....not as prominent. So I figured it would be a good idea to ask for a second opinion before labeling it as that. What do you all think? Any insight is greatly appreciated as always!

I was fortunate enough to be able to visit Morocco last year in May and tour the wonderful geology of the country. This will be a very short recap of the experience because frankly there are just too many things to share. For starters, the culture is fantastic. Morocco consists primarily of the Berber people and they are some of the friendliest people I've encountered. Very welcoming and ready to share some tea with you. Tea is by far the most common thing you will drink in country. I'm quite certain there were days that I had tea at least 8 separate times, and the tea was fantastic. If you've never had Moroccan tea then you are missing out (the mint tea in particular is wonderful). The cuisine is beyond amazing, and there honestly wasn't anything in country that I didn't like. Trying to replicate some of the foods has been a challenge (my tagine is getting close), but I suppose that just means I'll need to return some day. The country is also very safe throughout. As a solo female traveler, I felt comfortable at all times and was not concerned. However you should know that few people speak English. The most common languages people know are Arabic, French, and Berber, so there was some language barrier but as with most things, it was doable. My arrival to Morocco began in Marrakech where I was met by my guide who drove me out of the city, through the Tizi n'Tichka mountain pass at 2200m in elevation. Eventually we made our way to Tamdahkte and I stayed at a wonderful riad that was (as I would come to find out) quite open air just as most riads and buildings are in Morocco. On the way we stopped at a salt mine and walked through.

This was my first winter fossil hunting in NJ (or anywhere, as a matter of fact). Definitely a different experience from summer and fall. Less people, and much better fossils! Although the people I have run into were pretty devoted, which I can appreciate. Thought I would document my 4 hunts between December and this past weekend. First up, 12/16. On of my favorite Cretaceous brooks. Found an awesome variety of fossils, one of which turned out to be a Theropod tooth!

QUARTETnary - A card game about the geological time scale
paleoflor posted a topic in Members' News & Diversions
L.S., Wanted to raise some awareness on TFF because I expect many here will simply love this: A good friend of mine, Iris van Zelst (geophysicist at the German Aerospace Center in Berlin) has developed this really nice card game centred around the geological time scale: QUARTETnary The gameplay is based on the classic game Quartets (similar to Go Fish and Happy Families), where players try to collect as many sets of four cards as they can. In QUARTETnary, each of the sets represents four major events that took place during a specific geological time period. To win the game, you need to create the most complete timeline of Earth history, all the way from its formation 4.567 billion years ago to the appearance of us humans. The cards have been designed by Lucia Perez-Diaz (Earth scientist and freelance illustrator from the UK). The illustrations look amazing and I really like that they adhered to the official colour scheme of the International Commission on Stratigraphy. Iris sent me this nice set of cards for the Proterozoic: The game includes 15 sets of four cards in total (many featuring fossils): one each for the Hadean, Archean and Proterozoic eons, and one each for the 12 periods of the Phanerozoic. I expect QUARTETnary will become a really fun way to learn about and memorize the different geological units and major events in Earth history. Kind regards, Tim

Picked this one up at a rock shop when I was back in Philadelphia over Christmas. The lady working that day said this piece was bought by the owner with a bunch of dino bones (mostly vertebra) that the finder said was from Montana. No other info. The vertebra that were in the box with this were definitely dino, but in rough shape, so I didn't grab any. This is 13cm x 11cm x 8 mm thick. It is solidly lithified, and resembles agate. Based upon shape, my first thought was epiphysis, but do reptiles have those? Then I wondered if it were a whale epiphysis mixed in with the dino material inadvertently. But it is agate and very solid, which is unlike any cetacean epiphysis that I've seen. The patterning on the front and back also don't remind me of the cetacean epiphysises (epipysisi?) that I've seen. The texture does indeed remind me of dino bone. So then I wondered if it were a dermal scute. Thoughts?
