Symphyseal/Parasymphyseal Otodus obliquus Teeth from Morocco
MarcoSr posted a topic in Member Collections
I rarely buy shark teeth, but I saw a lot (see below picture) of small shark teeth from Morocco for sale on FB. I could see a good number of Otodus obliquus symphyseal teeth in the pictures of the lot, and one tooth that looked like an Otodus obliquus lower parasymphyseal tooth. Lower Otodus obliquus parasymphyseal teeth are much rarer than the symphyseal teeth. Per a personal conversation with Lutz Andres, based upon his research Otodus obliquus symphyseal teeth are probably 10 times more common than the lower parasymphyseal teeth. The opposite is true for Parotodus. I bought the lot and just received the teeth. I sent pictures to Lutz of a good number of the teeth, and we agreed that there were 16 symphyseal teeth and one parasymphyseal tooth in the lot. It can be very difficult to differentiate Moroccan Otodus from Parotodus teeth, and only large size can confidently rule out Parotodus teeth. However, in the Moroccan Khouribga faunas, Otodus obliquus are much more common than Parotodus. Group picture of the lot of teeth: Two symphyseal teeth: Symphyseal Otodus obliquus tooth, Khouribga, Morocco 21 mm SH Symphyseal Otodus obliquus or Parotodus tooth, Khouribga, Morocco 10 mm SH Parasymphyseal tooth: Parasymphyseal Otodus obliquus or Parotodus tooth, Khouribga, Morocco13 mm SH Marco Sr.- 2 replies

I went hunting today. With travel, commitments, but mostly rain, today was only my 2nd fossil hunt this month. I am addicted, and feeling withdrawal symptoms, taking any opportunity. This is one of my favorite locations but it takes a 2 hour drive and a 2 hour kayak paddle to reach it. So I put in 8 hours of travel for 4 hours of hunting. All my low water locations have deep water and are getting deeper.. rain scheduled for most of the next week, Did not find much because I was digging locations I had previously dug but today were in 4-5 feet of fast moving water. Took some quick group shots to give member a sense of what I was finding. Usually only the best shark teeth make the photos, but this 1st photo is every shark tooth I found. I think there is an Aduncus symphyseal in there. What do you think? Here are the non_shark I need to take better photos, but not tonight.. Note what I believe to be a Llama cannon bone , missing both distal and proximal ends.. @Harry Pristis just offered a Llama foot bones sampler that I believe has one of these. I kept it because of the size... it seems small. Some additional photos. One reason I love this spot is the variety of fauna that is possible, both marine and mammal. Enough for tonight, going to sleep..

Is this a symphyseal tiger shark tooth or something else? I'm struggling to get good pictures, since it's only an 8 mm slant height, so hopefully these will do. Compared to a posterior tiger: Thank you!

Found a new spot (new to me, but I'm sure many others know about it) Saturday where I found quite a few hemis, including my largest one to date, and one with very interesting colors. I also found the attached tooth, which I'm guessing is a symphyseal tooth (pathological maybe), but I don't have anything else like it. Is that indeed what it is and, if so, is it possible to tell what type of shark it is (genus)? Found near the Summerville/Goose Creek area. Thank you for the help!

Moroccan Parotodus parasymphyseal and Cretolamna biauriculata?
ThePhysicist posted a topic in Fossil ID
Hi y'all, I picked these shark teeth up from a local rock shop. The first is definitely a symphyseal/parasymphyseal tooth but I'm not sure if it's from an Eocene Parotodus or Otodus. I lean towards Parotodus because of the narrow crown and its significant curvature. The second I think is a Cretolamna biauriculata. The symphyseal is about an inch ~ 2 cm in length. @siteseer@Al Dente@MarcoSr@Untitled Parotodus sp.?: Cretolamna biauriculata?:- 4 replies

I was going through some of my shark teeth from the Calvert Cliffs (Miocene) in Maryland, and this Galeocerdo aduncus tooth caught my eye due its somewhat unusual shape (not including the fact that it's broken on one corner). I'm wondering if it might be a symphyseal tooth. From reading past forum posts, it seems like there's a range of Galeocerdo symphyseal shapes, from symphyseals that are pretty symmetrical to ones that are less so (such as mine, if it is one). For those more familiar with these teeth than I am, what do you think? Thanks for looking!

We were able to get out to visit the Calvert Cliffs area over the weekend and enjoy the nice weather and lower tides. We were able to take the kayaks out, water was a bit choppy on the way out but as time passed the wind calmed down quite a bit for the return trip. After beaching my kayak, within a few feet of it, I found a very small chub (first for me) and in great condition! Within a few more minutes I spotted the small shark vert rolling in the surf and knew it was a good day already. After some more searching, my wife found the biggest of the mako's pictured. We were also able to find three mostly complete Ecphora as well and some other smaller teeth. We didn't think we would beat the chub and mako this trip, but towards the end of our trip walking back to our kayaks I spotted a tiny black speck while surface scanning, I picked it up and had seen similar teeth posted here and in other groups and new exactly what it was. Was super ecstatic to have found my first symphyseal, cow shark upper. One to check off the bucket list for sure. Below are some pics from the day. In the process of getting a macro lens, sorry about the low quality on some of the up close pics. Also found the black flat bone fragment I wasn't sure what it was, so any insight would be appreciated!

Hi everyone, I think I found a year maker recently, and in good time! The 1st tooth pictured is what I am praying is a Pseudocorax affinis, which is incredibly rare here. The 2nd tooth is an Archaeolamna, I just need confirmation that it’s a symphyseal. Both teeth are Late Cretaceous. Edit: I forgot to add the size, 1st tooth: 12 mm, 2nd tooth: 10 mm @non-remanié @Al Dente @siteseer Happy Holidays! 1st tooth:

Hi all, For whatever reason, I never got around to posting this. After a relatively unsuccessful day at Bayfront Park back in 2018, my dad showed me this tooth, unsure of what it was. He said he had found it while sifting in the creek that runs under the bridge near the entrance of the park. I had never really bothered trying around that area because it was so far from any cliff exposures, but I suppose he proved that some of the best finds may be where you least expect them. The second he pulled out this tooth, my jaw dropped. It is a FLAWLESS cow shark symphyseal. I hadn't had a single one in my collection until then. I've never seen a better symphyseal than this one, not in a museum or anywhere online. It's absolutely perfect, with exquisite symmetry and phenomenal preservation. Undoubtedly the best tooth my dad has ever found. Although I was a bit jealous that he found it and not me, I was at the same time ecstatic because all of his finds go towards my collection. This beauty is one of my most prized teeth, as I am yet to see a more perfect specimen. The pictures do not do it justice in the slightest. It was found a while ago, but I thought you all would still like to see it. Enjoy!

Tried to get out before the ice storm in search of cowshark teeth (found none and hunted hard). Lots of small sand tiger teeth, including a crooked one and a symphyseal, and lots of split teeth. Lots of drum teeth, (the dull side is more interesting than the glossy side). Four angel teeth that stand up on their triangular base, two whose root is damaged. Two or three mako (broken). Lots of small triangular teeth (dusky, bull, gray? not sure what all they are). Lots of batoid/ skate teeth, but no stingers or denticles. One whole vert and a small disc echinoid. Lots ofsmall 'whale bone' and bits to go through. Not what I was after, but quantity if not quality was good.

Day of the Sandtigers: Second Symphyseal? 1/5/19
FossilsAnonymous posted a topic in Fossil Hunting Trips
Hello all, I hope you are having a fossiliferous New Year. To kick ours off, MomAnonymous and I went off to Brownies to check out the beach. It seems I really do need waders as I was unable to round the point even at low tide. We met @sharkdoctor on the point who had found an amazing bird bone in zone 10. We chatted for a bit, and he gave me a lot of information that could prove very helpful, and even invited me to a group hunt at Blue Banks. What a generous man. I get good luck when meeting other collectors! We putted around for a bit, finding some really nice sand tigers at one point and a lot of other, small teeth. Then we went to the bridge, where MomAnonymous found another symphyseal Physogaleus in the exact same spot as before! In all we got 137 small teeth. Not the best of days, but not horrible either. @Littlefoot @racerzeke @ShoreThing @WhodamanHD- 25 replies

Hi all, This tooth was found of one of my recent hunts along the Calvert Cliffs in Maryland. I found it at Bayfront Park/Brownies Beach. It is approximately one cm in length, relatively flat, and has multiple worn but visible bumps of enamel that could either be large serrations of some shark tooth or cusps of a symphyseal cow shark tooth. I believe it's the latter, but also recognize that it is a rather uncommon find. If it turns out to be a cow shark symphyseal, it would be my first one! Excited to see your takes on this one. I feel somewhat confident with my standing ID, but would love some confirmation. Thanks in advance!

The stratigraphic information for this locality is questionable and so is specified vaguely. The environment is marine shell hash that may span late Miocene-Pleistocene. Dr. Richard C. Hulbert, Jr. from FLMNH had this to say about the locality: There are two “formations” found near the surface in that area of the state. One is the middle to late Miocene Peace River Formation. The other “formation” possible is has been informally called the Okeechobee Formation by Tom Scott, and consists of the sandy shell beds formerly called the Caloosahatchee, Bermont, and Fort Thompson formations. On the geologic map of Florida published by the state’s geological survey it is not designated a formal name and is instead listed as Pliocene/Pleistocene shelly unit. Even if found in situ within the Plio/Pleistocene unit, such specimens could be reworked out of the Peace River Formation. If you are finding them in modern creek alluvium, it will be difficult to be sure which is their original depositional unit.
