From the album: Fossils
2.4 inch Otodus aksuaticus shark tooth from the Eocene Nanjemoy Formation of Maryland. This is a good example of the transition from obliquus to auriculatus, with serrations extending about halfway down the crown.-

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.

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.

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.

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.)

Looking for an Otodus Obliquus from the United States
MeisTravis posted a topic in Member-to-Member Fossil Trades
Hey all! I’m in search of an Otodus Obliquus, specifically one from the US. I have other shark teeth to trade. I have some Cretaceous teeth, Megalodon, Angustiden, Some hastalis. If someone has one they may trade PM me! I’ll gladly send some pictures of what I have to see if we can make a deal! Thank you!! -
This time I decided to draw some teeth from the group of Megatooth sharks. No point in showing original photos this time, since you all know what they look like. Now that the weather is finally taking a turn for the better, I'll be spending more time in the field again, so it may be a while before I get back to sketching again. And besides, Sara has just arrived and I need to keep her entertained.

I received the final piece needed for my Megalodon evolutionary set today! The hardest tooth to obtain by far was the Carcharocles mugodzharicus, and I would like to thank @MarcoSr for his help with that search as well as the generosity with which he shared knowledge about it. I'll mention that I acknowledge the various debates around species naming and went with the ones I believed to be the best fit. I kindly request that we not get into it on this thread.

In your opinion, these teeth are of an Otodus Obliquus

I am new to collecting meg teeth so I hope my question is not “dumb.” Are the tooth cusps on a C. chubutensis vestigial structures from the earlier three pronged tooth like on O. obliquus? I read a physics article about how the megs tooth serration evolves from the smaller prong teeth getting sharks caught on larger prey causing them damage. Did the improved serration as the sharks evolved to be larger lead adult C. megladon adults not having cusps at all? I hope the question makes sense.
