Archaeopteryx lithographica-tooth?

[rocket]

I did not find the possibility to answer on pics in other albums.

So, this is the link to a wonderful tooth

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

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

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.

Tooth replacement in Archaeopteryx is from underneath, couldn't it be shed?

It was Identified by the staff at the quarry his name was Mr Pöschl if I remember correctly.

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

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.

Gyrodus

talked to some friends, we all think its a tooth of a huge Gyrodus.

Nevertheless, a nice find
