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.
