A 0.8 cm long Acrodus tooth with  a nice structure ! Those are very common in some layers in the "Bonebed" in a quarry in southern Germany (Baden-Württemberg) but bigger ones are quite rare.

Wow! Amazing tooth. Very much resembles Ptychodus teeth like we find here in the cretaceous of Texas, which makes sense since they are both in the same order.

Thanks :D

But Ptychodus teeth are in general rare at your hunting spots or?

It depends on exactly which formation and what part of the formations you hunt. The easiest strata to find them in North Texas is the Kamp Ranch member of the Arcadia Park Formation (lower middle Turonian) and the basal section of the Atco formation (lowermost Coniacian), with P. whipplei being the most common but far from the only species in both of them. Even in those layers they are usually rarer than other shark teeth like Cretodus or Squalicorax. But they can be found, to varying degrees of rarity and species diversity, in almost every North Texas formation from Paraptychodus washitaensis in the middle Albian Duck Creek formation to Ptychodus martini in the early Campanian Ozan formation.
