Real Meg Tooth?
FossilsandScience posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey everyone, Thinking about purchasing this Megalodon tooth here, but want to make sure it's authentic first! Seller says it has no restoration and was found in Southeast US. It's 5.697" long. What do you think? Thanks in advance!

Found several of these while digging a hole for the swimming pool in our house. It was very surprising as I found hundred of them. Can anyone tell it is century old. I took a video of my discovery too.

I’ve heard of them being found in shark river and even big brook but I’ve never seen any there. Supposedly cape May has smaller teeth but I haven’t hunted there so I’m not sure.

I headed up to Lawrence Canyon last week and this is what I found. Looks like the area is finally being developed. Say bye bye to another interesting and productive San Diego site. In honor of the site, here are a few of my favorite finds from Lawrence Canyon. I'd encourage everyone to post their favorites too.

Hello! Last time I was here I posted about 50 pieces of barnacle which I thought were teeth. Good news is, this time I actually have teeth! I sent these in to another fossil ID place, and they identified a few of my teeth as possible lemon shark, and the 8th from the left as a possible C. hastalis. If anyone can help identify more specifically what sharks the teeth came from I'd really appreciate it!! Also, the big brown fragment on the far right in these pictures they identified as some kind of bone fragment- maybe it's a long shot but do any of you know what it could have come from??? I'm really curious about that one now. (Ignore the second and third from the right. They aren't interesting.) I can post more pics if needed.

Trying to figure out what I found, can anyone help?

I have not measured the exact size yet but from the overall size and looks, is it possible that this teeth is from megalodon? Or just a big great white teeth?

Hello, I've had a shark's jaw for quite some time now and I'm curious to know what type of shark it belonged to. Can anyone please give me some clues based on the photos I've attached? I'm a newbie and fossil neophyte. Thank you very much in advance, Luc

Hi, I recently bought this tooth from a friend, but I am uncertain which species it belongs to. The root is very thin with great white characteristics, but the lack of serrations on the blade is more like a mako. My best guess is that it is a Giant White Shark (Charcharodon Plicatitis). It measure 2.75 inches. The last 2 photos show the tooth in comparison to a Great White tooth on the right side and a Mako Shark tooth on the left side of the tooth in question. What do you believe it is? Thank you for helping me out.

Carcharodontossaurus tooth - real or fake?
fabio posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello I have just bought through an online auction my first fossil, supposedly a Carcarodontossaurus tooth but I'm in doubt if it is real. Can you guys help me analyzing it's authenticity? Description and pictures follows below: LOCATION: Taouz, Errachidia Province, South Morocco GEOLOGICAL FORMATION: Ifezouane Formation, Red Sandstone Beds, KemKem Basin Size and weight: 50.5 mm • 1.99 in, 13g DESCRIPTION Finest grade Carcharodontosaurus tooth. It is complete, from the base to the tip. Its lateral serrations are deeply developed. This tooth has been stabilized on its surface by Paraloid B-72 to ensure its stability and consistency. This process does not affect neither the color nor any of the characteristics. It simply makes the specimen better preserved in the long term. It has small fractures that have been glued but no restored or fabricated at the lower part of the tooth.

Hi! I'm Stefanie from Ohio and I am a new member on the site, though I've been a viewer for quite some time now. I've been a lover of sharks and shark tooth hunting for many years, and let me tell you, it is hard being a die hard shark lover living in Ohio. My shark tooth addiction has inevitably led me to uncover many other fossils, which has greatly expanded my interests as well. I've recently returned from a trip to Florida (where I seem to find myself often) and am needing some assistance id'ing a few finds, which is what ultimately prompted me to make this profile. From everything I have observed here, there is an abundance of very knowledgeable individuals and everyone is so kind and helpful. It seemed like the perfect place to come to ask for assistance. Anyhow, I look forward to getting to know everyone and sharing my finds along the way. Below is a picture of all my new megalodon finds from my most recent trip to Florida. Not too shabby for a few hours in the spoils. Thanks for taking the time to get to know a little about me!!

Hi there! My partner took a trip to San Francisco and I asked him to bring me back a shell(I collect shells) and he comes home with this! I'm absolutely stumped! No idea what this could be. Input?

Hi below are some gorgeous teeth found this week on a Cape Town beach. Please note not all teeth were found by me - some were bought from other lucky local hunters. I suspect the second large tooth might be a transitional Mako feel free to let me know what you think.Feel free to message me if you want any more info on the teeth. (Please excuse rusty calipers)

Recently I aquired this Carcharodon tooth from Sacaco, Peru whose serrate conditions seems a bit peculiar to me. I can't really decide whether or not this tooth is from a late-stage hubbelli or an early carcharias. The serrations seem to wear/taper off just short of the tip on one side and abruptly end near it on another, and some (although not all) of the serrations appears to be angled in a way, although I suspect some may be due to wear. My thoughts on the serrations keep seesawing in my head. Would this tooth better represent a late-stage hubbelli or a carcharias? Thanks for any and all answers. Lingual
