Thanks Roger! Oh 20 digs?  

 

Good luck! 

 

Thanks  

 

The first tooth seems to be a Steneosaurus tooth and the other one is also a croc tooth. Perhaps its a tooth of Metriorhynchus sp.

Steneosaurus is now restricted to the type species S. rostromajor following Young et al. (2020), and the Solnhofen tooth could almost be certainly Aeolodon priscus, as that taxon was previously considered a species of Steneosaurus and is found in Solnhofen.

The first one is 1.5 cm long and it seems to be a crocodile tooth. I think its a Steneosaurus tooth:

 

 

 

I like the root 

 

The second isnt that big with a length of 0.7 cm. I cant determine this one... Maybe also a crocodile tooth?

 

 

I know this is an old one, but just wanted to add my 2cts. to this discussion in case anybody lands on this post in the future, as I think the first tooth is actually an ophthalmosaurid ichthyosaur tooth: the ridges on the crown look rounded to me, as you'd expect from the plicidentine enamel folds of an ichthyosaur, and the consistent spacing and high density of them also speak to this diagnosis. In addition, the ridges stop equidistant from the tooth apex, a characteristic typical of ophthalmosaurid ichthyosaurs. And while the root may look too smooth for that of an ichthyosaur tooth, it's good to keep in mind that the teeth of ophthalmosaurid ichthyosaurs have a smooth neck with rounded cross-section.

 

As to the second tooth, the translucent tip reminds me of a fish tooth. However, as the specimen appears to bear carinae, metriorhynchid crocodile might indeed not be such a bad suggestion.

 

Either way, very nice finds! And considering the rarity of Solnhofen marine reptile material, definitely jealous!
