A seller sent me a video and picture of Rebbachisaurus teeth. But I’m not sure that is real or fake. May I get advice from you, please? Thank you 457fc075-f5d0-4428-86f1-00fee0f8d7dc.mp4

Hello! I got these stuff from Kem Kem. Any help with id? - Maxillar theropod? - Turtle claw? - Theropod indet? - Theropod indet? Thank you so much!!!!

Hi Everyone, I found some fossilized shark teeth in Poland (Książ Wielki area) where miocene-badenian age deposits are located. I will be grateful for helping me with it's identification. If any additional images are required, just let me know and I will upload more. Thanks!

Hi everyone! I bought a batch of fossils from Tegana Formation, in Morocco. Among the fossils there are those reptile teeth: The seller assures that the five in the top row are Spinosaurus aegyptiacus (or at least Spinosaurid species). The three in the bottom row are reported as Elosuchus cherifiensis. The seller is reliable, however I noticed that the teeth are all very similar to each other. Is there a possibility that they all belong to the Spinosaurus or Elosuchus species? Is there any way to tell the two types of teeth apart? Below I put a few photos of the individual teeth.

Hi! Tooth a friend of my recently aquired. Bought as an Afrovenator Abakensis. Location is Tiouraren hill, téneré desert, niger. 4,75 cm Is it an Afrovenator or perhaps any other theropod tooth? Crown based compared to a Carcharodontosaurus sp. Tooth from KemKem

Hi, everyone. I saw a teeth on a online platform. But I don’t know that is real or not. Because it’s so cheap. So, I hope to get some advice from you all. Thank you

Oregon boy, 9, discovers remarkable ancient find in grandma’s yard Oregon Live, Pacific Northwest. Yours, Paul H.

Hi, A pair of teeth I am interested in. The first one, 1.25 inches. Sold as a dromaeosaur tooth from Hell Creek. Is it actually a Nano? It seems quite big for a raptor from Hell Creek. If a raptor, it would be Dakotaraptor because of the size? Next one is a Tyrannosaur-- just over 1 inch. Is it Tyrannosaur or another large raptor tooth? I have sent seller a message about the exact location -- county and stuff.

Hi, I went to the fleamarket and bought these. One is some kind of shark tooth, the other a crocodile tooth from the miocene I believe. What do you think?

Hi, went to the fleamarket and bought this. I think they’re some pseudosuchian teeth.

Good moring. How's the teeth of carcharodontosaurus? Is that real? Thank you.

Hello everyone i recovered some dakota sediment in which i think i found an allosaur type tooth and wyoming sediment with what looks like a dromaeosaur tooth. What do you think ? I tried to do my best for the photos. that of allosaurus is 2.5 cm and the other 0.8 cm

I found this bone/tooth in a creek, here in SW, MS. I was wondering if anyone could ID this piece?

Good evening, May I know is any real Spinosaurus teeth in the box, please? Thank you.

This month I decided to take on the challenge of finding my first Kamp Ranch sites. It's not the easiest thing to do since, to my knowledge, the elusive layer is not mapped anywhere. I spent a lot of time scouring the waterways of North Texas and by the end, I came up with two distant potential spots for a couple days worth of hunting. I traveled to the first site one sunny morning and after a long walk, I finally made it to the water's edge where I met endless limestone slabs filled with Collignoniceras woollgari impressions, meaning I was just in the right place. I readied my rock hammer and began the search. It was mostly just oyster fragments initially, but soon enough I started picking some nice Squalicorax and tiny Ptychodus anonymous. The Kamp Ranch was pretty hard, and that meant that the Squalicorax rarely survived extraction. Even the Ptychodus, which are usually quite resilient, ended up shattering more than I'd like to admit. I built up a steady flow of Ptychodus anonymous before spotting an enigmatic crusher tooth. I was excited since it appeared to be very large and of a rare species, but it turned out only to be a fragment. What's strange about it is the flat crown and few yet thick transverse ridges on top. The only species I know of this nature is Ptychodus latissimus, but in Texas those are better known to begin in the Basal Atco (Early Coniacian). I did some research at home and found that P. latissimus has been observed in Middle Turonian outside of Texas, so I suppose it is a possibility here. Possible Ptychodus latissimus After some more finds like a huge Xiphactinus tooth and Cretoxyrhina cusp, I at last flipped the slab that would yield the definitive best find of the day. In perfect condition was the biggest Ptychodus anonymous I had laid eyes on. I was familiar with the fact that the Turonian P. anonymous morphotype was supposed to be larger, but it's always different seeing it in person. Initially, I wasn't totally sure if it was P. marginalis instead, but the taller crown and anonymous-esque marginal area led me to believe it was the former. P. anonymous A couple weeks later, I ventured out to my second site. This locality had a smaller exposure on timid waters, so I was looking forward to being able to hunt for freshly eroding fossil from the limestone wall. When I first showed up, I was once again greeted with limestone slabs containing Collignoniceras woollgari impressions, however I was struggling to even find a single shark tooth among them. I recalled reading in the past that the Kamp Ranch can be spotty, so the possibility that this locality might be barren was looming in my head as I traversed the creek. Once I reached the exposure, I pulled out the probe and danced my way through the limestone blocks. I skimmed through the whole exposure pretty quickly, but only came out with a few Squalicorax teeth and a big Cretoxyrhina from the gravel. I was a bit disheartened. This was such a nice looking location, how could that be all there was to offer? Cretoxyrhina mantelli in the gravel Desperate to salvage the day, I got down low and searched the under side of the lowest slabs. After dodging a spider, I spotted the outline of a Ptychodus sticking out from a shaley layer cemented to the underside of the limestone. The matrix was soft enough I could dig it out with my fingers. Then I noticed another... and another. This layer was extremely productive and soon I pried off a slab of it to process atop a boulder. I could not believe the number of teeth I was finding. Pristine teeth from just ONE slab Not only were the Ptychodus numerous, they were also diverse. Shawn Hamm in a recent paper listed six species of Ptychodus occurring in the Kamp Ranch. I didn't know it at the time, but after some cleaning, I have EVERY one of those species represented from only a day's worth of hunting! Some of the more special ones included P. mammillaris which was a new species for me. Also, I found an upper medial file tooth of P. marginalis(?) which are always a neat tooth position with their unique proportions. P. decurrens is one I usually don't associate with the Turonian in Texas, but they made it through and I managed to snag a textbook one. Ptychodus mammillaris Upper medial file Ptychodus marginalis(?) Ptychodus decurrens The Lamniformes were also plentiful, though difficult to bust out in one piece. Dallasiella willistoni, a common smaller tooth from the Turonian Huge Cretoxyrhina mantelli One of the coolest finds was not a tooth at all or even from a vertebrate for that matter. The Kamp Ranch is a bit famous its fossil pearls. When I spotted a perfectly spherical curvature from the slab I put in 110% effort to pop it out cleanly and not have it fly away into the flowing water below. It came out in one piece and after looking through the microscope, it has the polygonal structure expected for a Kamp Ranch pearl. Inoceramid Pearl. That rock it came from also had two Ptychodus anonymous and a Cretoxyrhina mantelli as well Towards the end of my slab-splitting, I found an enigmatic fossil. Its flat and a fishy bone look with a bunch of holes on one side. The other side is completely smooth. My best guess is it's from a Plethodid fish, but it looks pretty different from the South Bosque (also Turonian) Plethodid fragments I have in my collection. Possible Plethodid After a long and rewarding day hitting the slabs, I turned around to head for the car. Of course, my eyes were locked on the gravel anything I had missed on the way in. No teeth were to be had, but I did find a thin shale ammonite entirely separate from matrix. I have no idea how it managed to survive in the gravel. It's so delicate and even has the tubercles of the shell intact on both sides. It's obviously not from the limestone, but would this still be Collignoniceras woollgari? It was a great day. I'll be visiting both of these sites again in the future for sure! Finds at the second site: Top L to R: P. marginalis, P. mammillaris, and Undescribed species Bottom L to R: P. anonymous, P. whipplei, and P. decurrens Top: Cretoxyrhina mantelli Bottom L to R: Plethodid?, Dallasiella willistoni, Inoceramid Pearl, Cretalamna sp., and Squalicorax sp. Thanks for reading!

I think I mentioned here in the forum a while ago that I've moved house into the next phase of life and have therefore drastically reduced my collection and also have given up my workshop. This has meant for me that I don't go off collecting nearly as much as I used to. As a matter of fact, the last time I went was last fall. However, I do still tend to get the itch, and now that the weather is getting better and I'm off on my bike a lot, I decided today to steer off to my favorite shark tooth site to see if there might be a few little things which would still fit into the riker mount. I arrived there mid-afternoon and scratched away with my pen knife for a couple of hours, found a few things, mostly without roots, but not really anything I wanted to take home with me. I just made a little pile in a conspicuous spot which could be found by any kids which sometimes frequent the site. I figured it was about time to move on, but I'd just give it one more go at another spot. And lo and behold...out popped a cow shark symphesal! And then shortly thereafter a couple of tigers and a couple of makos. All within about 10 minutes. So it was worth the effort in the end and it was just nice to get my hand back in again. Here they are:

Surface finds, this afternoon:

A few Teeth A Pipis the soft tissues of Animal opalised ( geological miracle) A Gastropod with soft tissues opalised as well , after an event that Gastropod didn’t had time to retract in his shell and got mummified instantly in contact with high heat and salty water , after millions of years the cavity was replaced by silicate. It was studied from Paleontologie in Switzerland they told me it’s a Geological miracle when soft tissues are preserved.

Hi Guys i am a collector of opalised fossils for 50 years. i have some very interesting and rare opalised fossils . these are some opalised fossils I have in my collection.

Hello, I'm trading two small Protosphyraena teeth. Here are their info: Protosphyraena sp. 84.9 mya | late Cretaceous Molecap Greensand Formation Gingin, Western Australia These two teeth have a value of 20 USD in total. I am trading them away for any other fossil with roughly that value. Thank you for your interest

Got these two teeth from a little antique shop a few weeks ago and I'm unsure of the formation they came from and therefore the species. Both teeth are about 1 inch in length. Worn serrations are also present on them.

Quick question. How little can megalodon teeth be? I ask, because I have heard about "baby megs" previously, but don't recall seeing much discussion about them. I was looking through my tupperware container of small shark teeth and I ran across a tiny megalodon that I had not noticed previously. I probably thought it was a bull at a glance and tossed it in with the other common teeth. Now I am thinking I might need to examine my little "common" teeth more closely. Which led me to think of a couple of other considerations : 1) How small can megs get? 2) How common are "baby megs" compared to larger examples? 3) Do smaller teeth have the same serrations from the start, or do the serrations develop later when the teeth are larger? I don't have a photo handy of my little meg tooth, but will post one later this evening in this thread. Thanks in advance!

This is a creek find from SW, MS. It was found amongst other types of teeth. It appears the tip has broken off. Can anyone please identify it. Help is appreciated. Thanks in return.

Hi everyone, I'm elderly I guess and I enjoy fossils, rocks, gems and all things nature. I always wanted to do an archeological dig etc. Just fascinates me. Someone told me start by going shark teeth hunting and I did and found a few. I have been pouring over charts trying to figure it out and still confused. Some are similar to others. I'd love to know what kind of shark teeth they are and also I have a rock fossil I found circa 1980 on Lake Michigan. My Astronomy instructor at the time said "oh that's just 10s of thousands of years old not millions so of no consequence". He never said what it was and I was hoping to identify it as well. I'll start with the four shark teeth and I have four other pieces I think might be but not sure. Maybe not. hard to tell sometimes! They are all very small. i was hoping for bigger specimens. Anyway, all the teeth were found this past weekend at Colonial Beach "Fossil Beach" they call it in Westmoreland County, VA. That should help a bit. If anyone can help, it'll be appreciated. I have a few other fossils but bought ones. Oh one more question... does anyone here know of a good Geology forum that's well put together like this one??? This seems to be a very well run board. Impressed by the people here, how smart they are, how civil and how the board looks overall. Good job! Photos below. I was thinking Lemon shark for one? Hard to know. First one is four at the bottom I KNOW are teeth and ones at the top unsure about. Closer views of the bottom ones are the following two photos. I think the photos are good enough to identify. Thanks in advance for any help!

Hello! Help please with identification. Height - 3 mm. Age - uncertain: Early Eocene or Middle Miocene. Location - Ukraine. Thanks in advance!
