Questions on tapejarids



Greetings,

I've got some questions on tapejarids:

*Is the rostrum in Sinopterus gui and S.dongi almost
straight?

*Whats the angle of Sinopterus rostrum?

*Is Jidapterus edentus Dong et al. a basal tapejarid?

*What is the ontogenic stage of the Sinopterus
gui,S.dongi and Jidapterus edentus?


Mark
