rocket Posted March 15, 2023 Share Posted March 15, 2023 I did not find the possibility to answer on pics in other albums. So, this is the link to a wonderful tooth Archaeopteryx lithographica tooth - Members Gallery - The Fossil Forum Love to know more about it, who determined it as tooth from Archaeopteryx. I would love to see a close-up, too. Do not think it is Archaeopteryx @jacob86795 Link to comment Share on other sites More sharing options...

Troodon Posted March 15, 2023 Share Posted March 15, 2023 I understand the initial question considering how large the tooth appears to be after looking at the images of the dentition. Having said that I will not question the sources that were provided by Jacob. Publication on the dentition 1 Link to comment Share on other sites More sharing options...
oilshale Posted March 15, 2023 Share Posted March 15, 2023 (edited) If I see it correctly, Archaeopteryx teeth have roots. The tooth in question looks more like a fish tooth.

I agree if you compare it to those photos. Size, compression and the absence of roots really raises a question on its identification but Im far from an expert on these teeth.

I also had a second opinion when I took it to the LMU museum which also confirmed it.

oilshale Posted March 15, 2023 Share Posted March 15, 2023 I have received a reply from Prof. Oliver Rauhut, the curator at the Bavarian State Collection of Geology and Paleontology and chair at the LMU. His research focus is the Mesozoic terrestrial vertebrate fauna, especially the evolution of the dinosaurs. I have translated the answer (as good as I could): "So I have not seen or determined this tooth. It's also most likely not an Archaeopteryx tooth, although I can see where that determination might come from - the slight forward tilt of the base and the relatively abruptly recurved apex, which also occur in Archaeopteryx. The shape of the base also makes me think more of a fish. Alternatively, it could be a tooth of a small crocodile with the root completely resorbed. Pleurosaurs have the typical acrodonte rhynchocephal teeth; I would rather not expect them isolated, and also the shape seems to me to be too round for that, and it lacks the flank ridges common for rhynchocephals. Better pictures or examination of the piece directly might help." Even if it should not be an Archaeopteryx tooth it remains an interesting tooth. 7 Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC).
