    Extraordinary Common Teeth

    Hey guys, I've been off the radar for awhile .. work you know .. been working on Siggraph for those of you who are familiar with software development. Just wanted to start a new topic here .. This one is right at 3.00" - 7.62cm C. carcharias Bahia Inglesa Formation South of Caldera Provincia Copiapo III Regio de Atacama Chile

    Chubutensis or Megalodon?

    Recently I read a post on this forum about Chubutensis teeth looking like Megalodon teeth apart from their cusps. This is listed as a Megalodon but has cusps, or at least what appear to be cusps
  3. This fossil is being purchased because it is a large Chubutensis tooth. The cusp is not clearly visible, but the seller says that not all Chubutensis teeth have clear cusps. The discovery is in Beaufort, South Carolina.

    4.2 inch Chubutensis

    This time, it is a 4.2 inch Chubutensis tooth discovered in Bobert, South Carolina that will be included in the shark tooth collection! The cusps aren't that prominent, but I think they're great teeth!
  5. This is one of my Megalodon tooth collections. What is that sticking out here? Is it called a bridge? The Chubutensis teeth are sticking out like this. Is there a possibility of Chubutensis teeth? It's just a pathological tooth, right?
  6. Took a couple trips to Eocene/Miocene locations in Monmouth County, NJ. Thought I'd share some of my finds. First trip was on 11/17. Was a warm 60 degrees outside! Group shot of my finds. My first find was an erratic fossil from the Devonian with signs of bivalve/brachiopod, crinoid and Pleurodictyum. I also found this separate section of what I assume is a Crinoid stem Several bone pieces. Eagle Ray plate - my first ray plate found in NJ. Some of the shark teeth: Otodus obliquus - First time finding this species Otodus chubutensis - First time finding this species Physogaleus contortus Carcharias sp. Had to do some reconstructive surgery as it fell apart coming home.

    Otodus Transition Series

    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.

    Had a Toofer Weekend

    I wasn’t expecting much from this weekend adventure, been having a dry spell with the last few hunts and a lot of misses. Gave it the good OL’College try again and oh did it pay off big time with finding not one but 2 teeth in extraordinary condition on back to back days and 2 different epochs vastly separated from each other geographically which is really cool. Time traveling but without the DeLorean! (Front and back photos of the larger tooth) 2 & 5/8 inches from tooth tip to the larger side of the root; which would be about 66 mm.
  10. Hi everyone! I've been reading a bit about Megalodon's ancestors and trying to update my knowledge and I'm coming across some conflicting information. It seems everywhere I look has a different age range and there seems to be a debate between the genus. Some use Carcharocles and some use Otodus. I've been using Carcharocles for the lineage, is that officially out of date? Also what are the age ranges of the ancestors Auriculatus, Angustidens, and Chubutensis? I can't find any consistent numbers and some places seem to suggest they coexisted (Auriculatus with Angustidens for a short time then later Angustidens with Chubutensis etc.) is that true? Any insight is appreciated as always!
  11. Back out in the kayak today for a gorgeous day on the water and along the cliffs. I launched just before sunrise and had the pleasure of watching the sunrise over an extremely calm bay on my journey to the spot I had planned to check. After landing the trip started slow only finding two Hemis and a split Meg. Further along the beach things started to pick up, I found a small porpoise tooth and small Meg with a little root chip. Continuing on I found another heartbreaking split Chub next to a nice little mako, (I got a little discouraged at that point) but then sitting right on top of some rocks near the wash was a beautiful 2.6” Chub! Finally not broken! I finished off the trip with a couple nice Chesapecten shells and kayaked back to the ramp with a big grin.

    Birthday Fossil Hunt

    I decided to call out of work for my birthday and hit the beach to do some hunting. I kayaked out about 2hrs before low tide and had the beach all to myself the whole day. Found three dolphin teeth right after I landed my kayak, good sign for the day. Found some big hemis and a pretty chub on the walk, then when I got to my kayak I noticed the big shark vert partially buried right next to it! Definitely a better way to spend my birthday than working!
  13. A few days ago I arranged some megalodon tooth fossils in my collection in a row according to their size. I found two black teeth that were noticeably different in shape from the other brown ones, their long sides and thickness were almost equal, but the short sides were noticeably more curved and the crowns were more slender. I'm wondering if it's because they are belong to individuals of different genders? Or maybe the black teeth belonged to a different species, because according to photos of the excavation site, the black formation was below the brown formation. Besides, the bigger black one has a very small remaining cusps.

    Shark tooth Id

    I have two teeth I have had for a while questioning their identities. My first tooth is from south Carolina,found earlier this year, I am not sure if it is a meg or a chub on the remaining corner it appears to have a slight cusp.The second tooth I have had for as long as I can remember, it appears to be either a large near posterior great white or a huge bull shark tooth.Any help is appreciated, thank you!

    Is it a meg or a chub?

    I’m looking into this wonderful 5.59” Cuban tooth, but I’m having a hard time figuring out if it’s a meg or chub. It has cusps, but they’re minimal and not very obvious. Seller says it dates from early to middle Miocene, though that’s not very helpful in identifying this tooth. I’m thinking chub due to the cusps existing, but I’d like to gather more opinions on the matter.

    Possible chubutensis tooth

    So I have this tooth that I found up in south Carolina earlier this year, it's an amazing tooth as far as color goes, but does have "a small" bit of corner damage. But what I am wandering about it is (as you have seen in the title) I believe it could be a chubutensis tooth. I am no expert on this kind of shark but I noticed that the remaining corner looks to have an extremely small cusp if it is one at all. if somebody can tell please let me know, thank you.

    Shark tooth ID needed

    This pendant was purchased from a fossil seller in Florida where it was found. Was purchased as an Angustiden, but I am just curious if that ID is correct. To me, the cusps look small and the main body is too wide to be an Angustiden, but I am no expert! Appropriate 2 1/4” in length. Any help is appreciated!
  18. JorisVV

    Megalodon or Chubutensis?

    Recently aquired this tooth. Sold as a Chubutensis, but some thought it was a meg. Can anybody confirm it for me? Found in the clay from May River, Beaufort County.

    Monmouth Chubutensis

    Hi all. I wanted to share this chub tooth I found towards the end of 2021. From Monmouth, NJ, I think Kirkwood formation. One of my targeted species for the year and was able to find one in about 20 hrs worth of searching.

    Cusps of mega-toothed shark

    We should all agree that the side cusps of these shark gradually disappeared with evolution, but how did they deform in the process of shrinking and disappearing ? Does the cusps’s tip gradually move closer to the middle crown and fuse together? Just like the two teeth in the picture below, is the brown specimen older than the other?
  21. I plan to collect fossil teeth from cretolamna to megalodons, and arrange them in order of color and size. I have got these three and are still working on it. Although they are not big and not perfect, they’re still very beautiful and fulfilling when placed together. It’s quite hard to find the right size shape and color. Might need some help with the auriculatus.

    Meg or Chub?

    I bought this 4.8” tooth and it was advertised as being likely a giant chubutensis tooth, but said it was a Megalodon to be on the safe side. Can anyone here positively identify it? This was found in a river outside of Summerville, SC.
  23. DardS8Br

    Megalodon or Chubutensis?

    I bought this Megalodon tooth a while ago, but the shape of it has me wondering if it’s actually a chubutensis tooth Here are two images of the tooth. It’s 4.88 inches from root to tip. It was collected off the Atlantic coast of North Carolina.

    Aurora Dig Pit Fossils

    Soooo a few days ago new material was dumped at the Aurora Fossil Museum. Well, I made the trip there before the Saturday crowds, and was well rewarded!!! These were the best finds of the day =p btw the stuff underneath the shark verts are 2 stingray spines, a filefish vert, a burrfish bone, a beat up dolphin jaw bone, and what I think is some type of fish skull cap
