Troodontid gen. et sp. indet.
Left maxillary, premaxillary or Right dentary tooth. CH=4.5mm
Late Cretaceous,Djadochta Formation. Bayn Dzak, Mongolia
This is another Troodon-type tooth from Upper Cretaceous in Mongolia.
Note the tooth has relatively large denticles on the anterior carina.
This is the largest difference from the one which I uploaded previously.
別のトロオドン型の歯です。近心側のデンティクルの大きさに注目してください。
これが前にアップしたトロオドン型の歯との大きな違いです。
