5mm. Sea bream tooth. Miocene Burdigalian. Found at Owingen near where I live. -
From the album: Pisces
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.

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.

12x13mm. Upper frontal lateral. From the Miocene Burdigalian at Billafingen, Baden-Wuerttemberg. -
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.
