petrified ginkgo from US: is this real?
rocket posted a topic in Is It Real? How to Recognize Fossil Fabrications
I have had really a lof of ginkgo-leafs from dakota, but never some like the ones I show. Have been asked about if it is real or not. I would assume it is artwork. comes from US, cretaceous, this is the info I got Size of the leaf is around 10 cm wide (around 4")

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! Group Shot Devonian glacier erratic with Crinoids, Bryozoan and Brachiopod or Bivalve impressions. Gastropod Steinkern Ammonite Steinkern Crustacean claw piece A. phasolus Crusher Tooth Enchodus sp. Tooth w/Jaw fragment Squalicorax sp. (Crow Shark) A. kopingensis (Mackerel Shark) 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?

A Cretaceous frog with eggs found in northwestern China
Oxytropidoceras posted a topic in Fossil News
Ancient frog had a belly full of eggs in oldest fossil discovery of its kind.

Hello, everyone! It’s been a while since I’ve been on this forum, but I was finally able to make my way back up to Ladonia this week to hunt a little. I didn’t walk too far from the bridge and mostly just surface-searched through gravel bars; unfortunately, I didn’t fulfill my dream of finding a mosasaur tooth, but I did find some other cool things! (Please note that all measurements are in centimeters) 1. My favorite find today was this Xiphactinus tooth. I found it just sitting on top of a submerged (but very shallow) gravel bar. 2. I accidentally found this point after just picking up what looked like a black rock in the water. I’d love to learn more about it; I was thinking perhaps a Gary Point? 3. Next up is a tooth(?) that is so worn down I’m not even sure if it’s identifiable, but I thought I would put it out there in case anyone had any ideas. I was thinking perhaps Ptychodus, but someone suggested to me that it could possibly be Globidens. Any thoughts? 4. Fish bone? 5. Mosasaur vert? This is an unfamiliar shape to me so I’d love some insight. 6. Another mosasaur vert. 7. Bone fragment #1. Not sure if it’s possible to identify this, but it had a distinct shape, so I decided to just post and see. 8. Bone fragment #2. Also not sure if this will be identifiable. That’s all that I have for right now!

Hi all, I recently came across the enigmatic taxon from South Carolina (and apparently New Jersey) - Conosaurus Bowmani. It was named in 1851 from the teeth depicted here, found in the Oligocene either Ashley or Chandler Bridge formations It was misidentified first as a mosasaur (hence saurus suffix) and had been suggested to be renamed conosaurops, but that doesn’t seem to have caught on. Only a few specimens have ever been found that I am aware of, primarily teeth and a couple jaw segments. Two of which were in a previous post by ClemsonSkulls which I was reading this morning, which likely came out of the eocene in a SC limestone quarry. I also see mentions of it from the Cretaceous of NJ. I am curious if anyone has specimens of or knows anything more about this taxon. I have located 4 references for it, including some great descriptions of its tooth shape, but as far as I can tell there have been no elements past the jaw that have ever been ascribed to this ferocious predator, and there is no clue what it is or looked like. Hoping someone knows something more! Thanks all!

Hi all, I just got back from my first Big Brook journey and found many amazing things. I've figured out the majority of my finds but i am left with a few below that i could use some help on. I've attached pictures with measurements. Please let me know your thoughts! Once I've IDd these, i will make a post of my findings in the sites forum. If some of these chunks are too small to identify, i completely understand. Location: Big Brook Preserve, New Jersey. Found in creek from various methods of sifting and surface scanning. Period: Cretaceous, 70-72 million years old 1. I believe this is my first shark vert but would like confirmation. 2. These types of rocks were plaguing my new paleontologist brain all day. Can someone confirm what type of rock this is? This is NOT a fossil correct? My gut and from what I've seen is telling me ironstone concretions (The bane of New Jersey)? Two examples here: 3. Absolutely no clue, don't believe it is a rock though. 4. Bone? Is this enough to ID? 4. I thought these were plastic chunks at first. The brown one is definitely not though. The black cone has two perfectly symmetrical lines going up either side, seems odd. Doesn't sound like plastic when tapped though. Thank you in advance and please forgive my ignorance, very much a rookie at identifying anything other then teeth!
