Triassic tooth?

[Desm.2]

I am asking for identification of this fossil, my grandfather found this tooth, it is said to be a Triassic tooth.

It was found probably in Germany or perhaps in Poland. 1cm long tooth.

 

 

 

[Troodon]

Lets first start with do you have any information on where these were found and formation?  Size?  How many teeth am I looking at?

This is the same tooth

I only know its triassic, keuper, its probably from South germany.

1,2cm x 0,4cm

Thanks just saw your first 8 words in the initial post.  Very little is published to aid in ID's and I'm not that familiar with European Triassic material.   What I can add is that the Trossingen Formation is a unit in the Keuper.    Might be that since vertebrate material is found there.  Shot in the dark if you want , so can you take a SHARP closeup of the serrations in the circled area I want to see what the denticles look like.  Also in that area can you do a serration (debticle) count 2mm wide.

Hello, and welcome to the forum from a dutchman in France!

 

This tooth reminds me of what in southern Germany would be referred to as Batrachotomus kupferzellensis, but that is probably best identified by the outdated term thecodontia as 1) the somewhat older Ticinosuchus ferox from Switzerland and Italy has morphologically similar teeth; 2) Batrachotomus and Ticinosuchus, while both archosaurs with eventual affiliations to Crocodylus niloticus (the present-day Nile crocodile), have been traditionally grouped in different clades; and 3) the latest known occurrence of either Batrachotomus or Ticinosaurus is the Ladinian stage of the Middle Triassic, and thus falls just short of the Keuper. Alternative, and if accepting França, Langer and Ferigolo's 2011 adjusted phylogeny (see "Incorporating Decuriasuchus quartacolonia (Pseudosuchia) into the archosaur phylogeny" - link appears broken), the tooth may be attributed to "loricata indet.". In any case as killer tooth, and a beautiful sentimental piece!
