Early Monocuspid Teeth

 

The rhamphorhynchoidea generally had thin monocuspid teeth that curved evenly and reduced in breadth evenly, with a constant cross section throughout.  These teeth were hollow rooted.
 

This drawing of a Generalised Rhamphorhynchus tooth shows the degree of the curving and the cross sectional shape.  The tooth is very even in its form and shows a consistent section throughout, with a hollow base.

There is an enamel cap to the tooth and there is a small strip of enamel running down the front and rear of the tooth..

This tooth form was quite consistent, with a variation in size between species.  Some species show a much larger tooth form at the front of the jaw.

     

Dorygnathus banthensis shows a good example of how the size of the teeth reduce towards the back of the jaw.  Other forms like Campylognathoides show a more even tooth size throughout.

Scaphognathus with a more even sized tooth distribution.
