Root length 1cm. Lower lateral Burdigalian, Miocene Obere Meeresmolasse Formation From the NW Lake of Constance area. -
I found this today at the Early Miocene Burdigalian site and was wondering if this might be a Cetacean tooth. It's missing most of the tip, but I think it's still possible to judge. It's 2cm. long.

I visited my favorite shark tooth site in the Miocene Burdigalian again today and along with the usual teeth I dug out the following objects. The first is obviously a vertebra, and I don't think it's fishy, but rather mammalish in my humble opinion. But I'm not at all sure about that. I've found teeth from Cervidae here before, so I'm thinking that maybe that's the case with the vertebra? Measurements: Ø13-15mm x15mm. long. I haven't got a clue on the next 2 items. The first is 10x4mm. and the second 15x5mm. Any suggestions would be appreciated.

A new fossil odontocete-related paper is available online: Mariana Viglino; C. Maximiliano Gaetán; José I. Cuitiño; Mónica R. Buono (2020). First Toothless Platanistoid from the Early Miocene of Patagonia: the Golden Age of Diversification of the Odontoceti. Journal of Mammalian Evolution, in press. doi:10.1007/s10914-020-09505-w. Dolgopolis is the first fossil platanistoid known to have relied on suction-feeding rather than raptorial behavior, considering that the xenorophid Inermorostrum and the delphinid Australodelphis are the only extinct odontocetes besides those belonging to Physeteroidea or Ziphiidae that resorted to suction-feeding to capture prey. In retrospect, the feeding behavior of extinct platanistoids wasn't uniform as previously thought, and the description of Dolgopolis on top of so many other extinct platanistoids is another reason why most people don't know that Platanistoidea was once diverse and widespread in the Neogene, only to see its diversity crash to just one genus by the time that humanity came into being.

7x6mm. This partial tooth was found in the Miocene Burdigalian at Billafingen, B.-W., Germany. It may be a member of the Eomyidae family. Thanks to Harry Pristis and the others in helping with id. There also seems to be the possibility that it comes from a small cervid. -
I visited my favorite shark tooth site in the Miocene Burdigalian again today and made a few nice finds along with something that has me scratching my head. I'm pretty sure it's a partial mammal tooth, but have no idea what it might be. It seems to be from quite a small ruminant anyway, judging by the chewing surface, measuring in at 7mm. wide x 6mm. high. I checked out @Harry Pristis albums, but couldn't find a match. I've posted views from first the chewing surface, then 2 sideviews, the root and the last one is the side which appears to be broken. Any ideas anyone?

I'm really stumped with this one. Also found at the local shark tooth site in southern Germany near the Lake of Constance. It is hollow, filled with sediment and the "shell", or whatever it is, is just 2mm. thick. The patterns with the recurring isosceles triangles are intrigueing, but I really have no idea what this could be. It looks like it would have had a conical shape if it was complete. 4cm. wide at the base and 3cm. in height. I'd be very interested to hear your opinions on this.

I found this today at my local shark tooth site in the Miocene Burdigalian. It's a rather unique find for this site if I'm correct in thinking that this is really a bone fragment. It's not all that well preserved, so if it is one, it's probably not easy to identify, but I thought I'd give it a try here anyway. It's 3cm. long. Anybody have an idea?

I found this little guy amongst the usual Carcharias and Mitsukurina teeth at my often frequented spot in the Miocene Burdigalian (Obere Meeresmolasse Formation) in southwestern Germany and am a bit stumped, so I'm hoping that someone here can help me out with the id. The longest edge is 6mm.

Hi everyone, saturday I went on my 2nd fossil hunting trip with my fossil club to the Wienerberger quarry in Rumst in the Rupel area near Antwerp (Belgium). We hunted mainly in a thin Miocene layer dating back to the Burdigalian around 20.43 - 15.97 million years ago. We found many shark teeth, most of which are C. hastalis, but there are a few I can't quite identify as shark teeth are not really my area of expertise and I was not acquainted with the location until my visit. So I was hoping some experts could me out or someone who is familiar with the species from the location. I did send an email to one of the excursion leaders from the trip, but he admitted not being a sharkteeth expert himself either and couldn't help me much further with ID's. So any help would be welcome. So the first batch of teeth are what I all believe to be C. hastalis. I am pretty confident with my ID on them but the other teeth are a mystery for me. These two teeth are pretty beaten up. The tooth on the right has no enamel layer anymore and I doubt an ID is impossible. But the tooth on the right could be beat-up C. hastalis but I am not sure, it also kinda looks like a pretty beat-up Carcharocles angustidens. The latter can be found at the location and are usually found in the bad condition due to the fact that they were present in a now lost layer a little bit older than the one were most shark teeth were. But as said before I am not an expert and I am just purely speculating with the little info on the location I have. I don't really know how to ID these teeth. Are they C. hastalis but located on different locations in the jaws than the previous C. hastalis teeth or do these belong to a different species? Then there are these 3 teeth that I don't know how to ID We also found a few small shark teeth of which I believe they might belong to a different species than C. hastalis And then the last tooth is this one, on first sight it kinda looks like a C. hastalis tooth but when you take a closer look you can see that the edges are serrated. So I wonder whether anyone know what species this could be? Well that were all, I would really appreciate some help for their ID's Thank you in advance!

1.5cm long. I'm going with this species since it appears to be the only one in the literature on the German Molasse Formation. My very first self-found symphyseal! Yay!! Burdigalian Miocene Found at Billafingen, B.-W. -
I found this tooth today and was very happy with it, since it's the first of its type that I've ever found at the southern German site in the Miocene Burdigalian which I visit regularly. I'm just wondering if this might be a Hexanchus sympheseal and if so, which species might it be? The tooth, which appears to be missing one barb at the one end, is 14mm. long.

1.5cm. long. Burdigalian, Miocene. Found at Billafingen in southwestern Germany. Eagle ray barb partial. Not absolutely sure about the id, but it certainly looks like the photos of that genus that I've seen. -
The weather has been so nice here lately that I decided to go for my first bike tour of the season yesterday. I don't like to over strain myself on the first trip, so I chose a site in the woods on the edge of a village about 10 kilometers away as my goal, knowing very well that I could spend a couple of hours scratching away in the sand and grit with my pen knife in the search for small shark teeth in the Miocene Burdigalian exposure. I have some idea what 3 of them might be, but I'd nonetheless appreciate confirmation or correction of my assumptions. I'm however not at all sure what the last 2 might be since I see just too many possibilities and am hoping that someone could set me on the right track. @MarcoSr @Al Dente @fossilselachian @Woopaul5 I'll number them for convenience's sake. Thanks in advance. 1. Mitsukurina lineata ? Goblin shark lower lateral ? 10mm. long. I think that the next 2 are both Carcharias acutissima ? Sand Tiger upper anterior ? 2. 19mm. 3. 25mm. 4. 11mm. 5. 16mm.

5mm. Sea bream tooth. Miocene Burdigalian. Found at Owingen near where I live. -
Hello to the teeth experts. I was just wondering if this tiny tooth (5mm.) belongs to a drumfish. It's somewhat differently shaped than the others I've found here (Miocene Burdigalian of southern Germany), but I think it fits the picture.

Took another trip to one of my Miocene Burdigalian sites on my bike again today and I was just wondering if this set of teeth might come from a Notorynchus cepedianus shark.

There are a couple of sites in the early Miocene Burdigalian not too far away at all from my home, so often when I take a tour on my bike I head off to one of them and scratch around in the gravelly sands with a pocket knife for a couple of hours in search of shark teeth. They come from practically the same time frame as some of the ones at Calvert Cliffs. I've already posted a few things from these sites here in the Forum in the past. I've been putting down most of the finds simply as Carcharias sp. and leaving it at that, but lately I've been wanting to get a bit more specific, which is the reason for this post. I'd like to show some pics and ask you experts if you think my guesses are correct or if I'm completely off base. Please imagine a question mark beside the names 1. Carcharias cuspidata. 18mm. 2. I'm stumped on this one. 12mm. 3. Carcharias acutissima. The longest being 22mm. 4. Odontaspis reticulata. 12mm. 5. Also unsure. The longest is 13mm. 6. The top 2 Carcharhinus brachyurus 8mm. Not sure about the other two. Thanks in advance for your suggestions.
