Hi, I was wondering if anyone could help identify if this is a tooth, and if so, what kind? Found off the Big Brook Preserve area in Monmouth county NJ Thank you!

hi everyone this is matt again today in the creek I found this very big coral fossil here is few photos

Hello Folks! I want to get better at identifying fossilized teeth. My family and I spend a lot of time hiking through Jurassic and Cretaceous deposits in the western US that contain largely vertebrate terrestrial fossils. We've found a lot of fragmentary bone, and over the course of picking up a few thousand bone fragments, have developed a pretty good eye for telling what is bone and what's just pretending to be bone until you bend down to pick it up. Teeth, however, we're far less adept at identifying. Wandering around the desert, without training wheels, how am I to tell what a fossilized tooth looks like if I've not seen a tooth? Hm... Luckily, we've stumbled upon enough obvious examples of teeth that we do have some data on what they look like - but precious little data. We've only ever found a handful of easily identified teeth, so we're not so good at identifying the poor quality stuff. Sometimes the tooth structure just looks like chert/chalcedony, and sometimes there are similarities to the structure of bone. What are some key features I can look for that are unique to teeth? Below is an example where the Allosaurid ID is only given away by the serration imprints left behind - the "meat" of the tooth just looked like fracture chert/chalcedony. I wouldn't be able to prove it was tooth material without the serrations. Allosaurid tooth (Brushy Basin) - ~1.5inch length Another tooth (~half inch diamter), this one from the Cretaceous Menefee, found nearby crocodile type scutes (Deinosuchus?), but whose core has porosity similar to fossilized bone. Very different structure from the Allosaurid tooth, but the texture of the outer layers tell me this isn't just a bone. I believe this could be up in the root of the tooth, and these hollow channels are what is left of the blood vessels that supply nutrients to the teeth. I've had a hard time finding any example pictures online of a cross section looking into the root of a fossilized tooth to confirm. Opinions? Anyone have good example pictures of tooth root cross section? In situ in the same boulder as the above tooth. More porous core. Another example from the same boulder. Cast remnants of another crocodilian tooth (Osteoderm was in situ in the same boulder) from the same layer a mile away from the above examples Another example I suspect is a tooth from the Menefee, found in float. Porous structure within looks similar to decayed haversian canal structure we find in bone, but the structure as a whole doesn't strike me as bone. Small <1cm Goniopholid tooth from Jurassic Brushy Basin. Without fluting and external material, I'd have a hard time convincing myself this was anything but some small chalcedony inclusion or other in the sandstone Another 1cm (tooth?) I would brush off as inconclusive if not for the context of being next to the above tooth Does anyone have any wisdom to give to help discern bone fragments from teeth? Thanks for taking a look! Ben

Hello everyone on the forums. Please tell me if this is a genuine saber-toothed tiger skull.

Is this a fossil? Maybe fenestella? Or is it natural

I found this tooth yesterday on my backyard while working on a project. It was under about 5 feet of rock. This house was built back in 1960s and to my best knowledge this side of the backyard wasn't excavated - there was a serious layer of rocks. To what animal does this tooth belong? I can't figure it out...

Hello all! A few finds in some Texas Cretaceous Woodbine Micro Matrix that I could use some help in ID'ing. Not sure if all are just fish teeth or maybe something else? All are around .25 inches or aprox 6 mm. Thanks!! 1. Has a very interesting texture and a distinct pattern on the base 2. Seems to have same pattern on bottom - sadly only half 3. The last one.

Hi everyone, I was on my way to my doctors appointment. I was walking to the door, when this caught my eye in the gravel. I thought it was wood at first, but I was mistaken. It’s definitely a rock. It was found in Twin Falls, Idaho, near the sidewalk. I’m looking for confirmation. Is this petrified wood? If it is, it’s my first find of 2023! Jared

I think this is a snake head? I found it in northwest Missouri around Grand River. It's approx 1.5" long, 1.25" wide (widest point) and head area is .5" tall. It is rock with some quartz in there.

Hi, my father has this fossil tooth/claw, but he doesn't remember anything of it. He doesn't remember where he got it, where the fossil is from, etc. I was wondering if any of you have some idea of what kind fossil can it be? Thanks!

Is this genuine praying mantis amber? The photo is hard to see, but please forgive me. Praying mantis in a barmite egg If anyone knows, please let me know. Thank you so much to everyone on the forums.

Is this stag beetle amber? barmite Myanmar product If anyone knows, please let me know. Thank you so much to everyone on the forums. Thank you.

Recently went to Melbourne to go snorkelling for whale and Meg teeth and came home with some not bad specimens and saw some quite large vertebrae

Found these two shells while hiking in the Panoche foothills in CA. Not near the ocean so figured they could be fossils, yeah? They are around two inches (5cm?).

This is probably one of my best days out in the Paleocene I’ve had yet. I went to purse state park today and upon arriving, there were at least 6 cars. The beach was flooded with people, and boot prints were all over. It seemed well traversed. The tide was also coming in, with some of the beach inaccessible without wadders or high boots. It was slow going on the first half of the day but the second half couldn’t have been better. I was finding one stunning fossils after the next. This was a pretty good outing, and I will have to return as soon as possible. Here are all the finds: Everything pictured: I found a few sand tiger teeth, a back bone of some kind, 2 pretty nice sized Otodus teeth, and a complete ray mouth plate! This was a really good find I am extremely happy about this. Only a foot of beach had been exposed and I was finding a lot on these recently kicked up cobbles. Nobody had been around and the surf must have mixed up the gravel to the top of the beach where it was redeposited. A ton of people were on the beach, and there was a huge tide coming in, and this managed to be one of my best days in the Aquia. Closer up: A really nice little hound sharks tooth. These are my favorite tiny sharks teeth to find here. There is also a couple of sand tigers, a scapula (?) of some kind (crocodile? Turtle?), 2 nice Otodus teeth, and a show stopping ray plate to top it all off. This is my first complete large ray plate. I have a couple other small ones but this one is huge. Flipped: The ray plate is so cool. I am very happy that I came at high tide I think I will start doing that more often now. Lots of finds to be made! Ray Plate and Otodus: This was such a good day. I think the Aquia formation might be one of my favorites. I want to go out to Virginia at some point to collect the Aquia it’s been a while and I know there’s good stuff there. Thank you guys for reading this! I really had fun out there with a parking lot full of cars.

Please can someone identify this fossil?

Hi, I'm very new to this and went out looking for fossils today in Seafield, Fife (Scotland). I found a what I think are horn coral? And also something thst looks like a tooth, if anyone could help identify it please. Forgive my naivity if it's nothing! Thanks in advance

Recently, after going to my favorite fossil store, I aquired a Otodus Obliquus vertebrae. It came from a formation in Morocco, and is approximately 54 million years old, from the pliocene. Otodus is an extinct mackerel shark, related to the far larger O. Megalodon. The fossil is approximately 10.5 centimeters or 4.13 inches. I was wondering how large the shark would be relative to this vertebrae (assuming this was the largest vertebrae from the shark.)

We have several of these.

my father found this at work, it was found in southern Ontario Canada. was curious if anyone knows what it might be, im thinking coral or possibly a sponge. thanks in advance.

Recently for Christmas, I received the marvelous gift of a bunch on different unprepared fossils from an unknown location in Nebraska (Purchased of the auction site). The first piece I started was a smallish jaw from an oreodont that I think turned out ok. I still plan to clean up the teeth a bit, but I'm not sure what to do next, as this is the first time I've prepared anything other than Green River fish. I'm considering removing it from the matrix entirely, but I'm concerned about the stability of the fossil, as the matrix is quite crumbly and the back has been consolidated by whoever found it, along with aesthetics. Any advice as to what to do next would be appreciated (Or if anyone knows what it is more than an Oreodont)! Thanks! Dimensions of the jaw are 14cm by 6cm, or about 2.3in by 5.5in. Unprepared After a few hours of using hand tools and my Dremel Current state: Front Back

any idea on this one found on a gravel bar one hour north of new Orleans , thanks for your time IMG_1598.MOV

Found this interesting textured fossil at the beach in St Augustine Florida. I find lots of bone fragments and skull caps and such here but never found anything this texture
