This pseudodont dentition possibly suggests a possibility of a beak being present as in turtles and birds.
2.
There was also a premaxillary boundary between third and fourth pseudodont tooth which exposed vomerine dentition by creating a gap.
3.
In " T . alexandrae " the premaxilla was toothless, beaked, with pseudodont dentition of bony projections.
4.
Upon further examination, the other characteristics found true of this fossil were a striated external surface of bone with smooth bone resembling " pseudodont teeth ".
5.
The three " teeth " previously illustrated are not teeth at all, but more like bony extensions of the premaxilla-" pseudodont " teeth similar to those found in " T . borealis ".
6.
In " T . borealis " the premaxilla is hooked anteriorly, small, extending into long rostrum, with a sharp horizontal ridge along anterior tip of premaxilla separating the external striated bone from smooth bone of " pseudodont dentition ".
