I just got a package today of fossils from Morocco. Most were just your common mosasaur and otodus teeth, etc. But this one just doesn't look right. Can someone please help me identify it? It looks like a rather wide Otodus tooth but has a prominent ridge running down the middle. It also has a very large root and the tooth sits on quite an angle from the root. Appreciate any help. It is 2 1/2 cm across at the root.

This was my first angi, and maybe my second shark tooth ever. Still holds a very special place in my heart.-

By far my largest nice condition angustidens. I only saw the broken corner of root sticking out. -

This is my largest Megalodon to date. It measures almost exactly 5.5" and was found in a lag deposit in the Summerville area. -
I've often wondered what some of the fossil shark teeth in my collection would look like if they didn't have root damage, missing cusplets, etc. Many of these imperfect fossils are somewhat rarer and/or otherwise favorites of mine, so I've been hesitant to permanently alter them through restoration. Recently, I decided to go ahead and restore several of these teeth--but wanted to do so in a way that wouldn't be permanent. The technique I've adopted is to first paint the broken surfaces of the teeth that I want to restore with a couple of coats of liquid latex. Once the latex is dry, I then shape and build restored roots, cusplets, etc. out of epoxy putty on top of the intervening latex layer. The putty sticks well to the latex and can be shaped to match the tooth without directly touching or bonding with the fossil. In most cases, when the putty is dry, the restored pieces have been easy to detach with a simple tug, as the putty doesn't permanently bond to the latex (the latex layer itself is also then easily removable/peelable from the fossil). In a couple of cases, I have unfortunately caused a bit of damage to teeth in the process of removing the restored pieces. Once, because I inadvertently pushed the putty into an indentation in the root of the tooth and as a result it couldn't be cleanly pulled off/out. Another time, the tooth I was working on was more fragile than I realized and the force of pulling the putty off caused a fracture. Luckily, the damage wasn't too extensive in either case, and I've (hopefully) learned to be more careful. I had never attempted to restore teeth before but I found some very some helpful tips for doing so on TFF here and here. A few additional notes on materials and methods: The "white" (it's definitely more of a gray) epoxy putty I've been using is Apoxie Sculpt, which I ordered from an art supply store. I ordered the liquid latex online as well. For root surface texture, I've also used the liquid latex to create several small surface molds from different fossil teeth, which can be pressed into the epoxy putty before it hardens (as recommended in one of the TFF posts linked to above). I use an X-Acto knife for texture and shaping as well. I use fine sandpaper of varying grits, from 400 to 2000, to smooth the "enamel" portions of the restorations. I use acrylic paint for the colors--sienna, umber, tan, black, white, red, blue, yellow--and finish things off with a clear matte or clear gloss acrylic glaze to improve durability (the gloss glaze is for "enamel"). I use small amounts of non-permanent Museum Wax (ordered online) to attach the final restored pieces to the original fossils. Below are several of the results (the original teeth and the detached restored parts are on the left and the final teeth with their restored parts "attached" are on the right of these images). Otodus obliquus tooth from the Eocene of the Isle of Sheppey, Kent, UK -- restorations to the root and a missing cusplet: Cretodus sp. tooth from the Cretaceous of Texas, USA -- restoration to the cusp (I did a better job of color matching on the lingual than the labial side of this one): Cretodus sp. tooth from the Cretaceous of Texas, USA -- restoration to the root and a missing cusplet: Dwardius siversonii tooth from the Cretaceous of Stary Oskol, Russia -- restoration to the root: Otodus aksuaticus tooth from the Eocene of Maryland, USA -- restoration to the root and a missing cusplet: "Hubbell" Otodus megalodon tooth from the Mio-Pliocene of West Java, Indonesia -- restoration to the root and a small part of the cusp: Carcharodon carcharias tooth from the Mio-Pliocene of Florida, USA -- restoration to the tooth and a small part of the cusp:

Hi all, For a few months now, I occasionally go searching for shark/ray teeth in an old industrial area in Aruba. I found hundreds of smaller shark teeth (probably carcharhinus) and a handful of very cool & much larger teeth (likely otodus angustidens). This morning, I went walking the dogs there and stumbled upon a chunk of a much larger tooth! Could it be the megalodon? it could be a larger specimen of an O. Angustidens but the proportions are not quite the same… I'll let the experts judge for themselves. The (almost) complete O. Angustidens tooth in the middle is 2’1 inches (5,3 cm) long.

Thought I would share two of my favorite finds from Chandler Bridge Creek in Summerville, SC. The smaller one was in near pristine condition.

Good evening everyone! Happy New year to all of you! This afternoon, walking on the beach a strange stone has captured my attention. I have no idea wat it can be...It look to me shaped in a particular way...(See photo) Is it a stone? A tool? A tooth? Anything else??? I wonder if you would be so kind to help me here, I have no knowledges at all on this subject Many thanks in advance! Ludo2

Took a trip out to the Aquia formation along the Potomac river on Friday, I tend to go to the Calvert Cliffs a little more frequent so it had been a little while since I’ve been to this site. We had some rough weather and high wind earlier in the week so it had my hopes high. I arrived on the beach a few minutes before sunrise. I started out by finding a couple heartbreaking Otodus teeth that were just buried enough in the sand to give me hope of them being full. Alas, three times in a row I unearth a busted tooth. Finally my luck began to turn when I found a gorgeous Paleocarcharodon orientalis! A rare tooth for this site and it was in great condition. I continued on and to my disbelief there was another amazing condition Pygmy! I couldn’t believe my luck, then I just couldn’t help but laugh when saw a third great condition tooth. I could go a handful of trips and not find a single one, and here I am with three! The biggest only being .99” but the serrations on them make my heart skip a beat! But that wasn’t the end of my day, I finally find nice complete Otodus measuring 1.31”. On the walk back I managed to snag two more smaller Otodus to round out the trip. It was a crazy day; the weather was amazing and the river was calm, I had a bald eagle flying over head and I found three amazing Paleocarcharodon teeth! Thanks for reading, until next time!

I haven't posted in quite some time, but I thought I'd share my last few trips to the Potomac river. I've made three trips in the last few weeks, with pretty good success. The second trip I found my 4th Otodus obliquus that exceeds 2" on the slant height, and the largest I've found at Purse state park, sadly it has major feeding damage... On the last trip I found a monster Striatolamia striata (?) (These larger teeth are typically considered macrota, but I'm not sure if that species is present in the Aquia Formation.) I'm also including a few pictures of a large shark vertebral centrum I found at the end of September on a trip I didn't take pictures for. Lastly, I thought I'd include the 4 2"+ Otodus teeth I mentioned earlier, since finding one was my main objective for a long time. The largest is 2.75" slant height. Thanks for looking, and good luck to everyone on their next trips!

Hi all, Looking at purchasing this tooth. To me it looks like a transitional morphology between O. obliqus and P. Orientalis, but would like a second opinion. Thanks in advance.

I'm putting together an Otodus sp. transition set of well-matched (similar size and position) teeth, in the approximately 1.4-1.5" range. This is the second such set I've put together, but for my current project I'm looking to build a larger (in number) set that includes examples from as many different locations and time periods as I can, i.e., not just one O. obliquus, one O. angustidens, etc., but hopefully multiples of each representing different time periods and geographic locations for the chronospecies. I'm off to a pretty good start, but there are several locations and a few specific time ranges that I'm still after, and I anticipate that I'll be continuing to build this set for a while. As I've been working on this project, I thought it would be interesting to put together some photo montages of the teeth to illustrate the evolution of Otodus's cusplets and serrations, from O. obliquus to O. megalodon. I've seen similar images elsewhere but wanted to see what I could produce using teeth from my collection. Not all of the teeth shown below are from the set I'm building--I've also included images of teeth that are too large or small for the set but that fill in gaps and help illustrate the transitions.
