Pfeilerzähnen

Pfeilerzähne are a type of fossilized dinosaur teeth found primarily in Europe and Asia. They are known for their distinctive pointed shape and are often associated with early tyrannosaurids and theropod dinosaurs. The name "Pfeilerzähne" is German for "pillar teeth" due to the tooth's unique, pillar-like shape.

Pfeilerzähne are typically found in Jurassic and Early Cretaceous deposits, which dates them back to the Middle and Early periods of the Mesozoic era, roughly 155 and 75 million years ago. These teeth were formed in a number of different dinosaur species, including the theropod Coelurus and the early tyrannosaurid Dilophosaurus. The high concentration of dentine and the structure of the enamel make Pfeilerzähne some of the best preserved and most durable dinosaur fossils.

The shape and structure of Pfeilerzähne have made them an important area of study in paleontology. Their pointed shape, for example, has led some researchers to suggest that Pfeilerzähne were more effective for penetrating prey, while others have proposed that they may have been useful for grasping and holding onto food. The grouping and correlates of specific teeth types and characteristics have been studied in detail, leading to a greater understanding of dinosaur evolution and possibly insight into the eating habits and evolution of these species.

Pfeilerzähne continue to be a significant area of study and a rich source of information about the evolution, behavior, and life forms of the dinosaurs.
