Cranial crests in pterosaurs

[Hebert Bruno Campos <hebertcampos@bol.com.br>]

Dear colleagues,

I was surprised when seeing the reconstruction of the cranial crests of 
some pterosaurs in Frey et al., 2003a (Fig. 10)!!!

Please, anybody read the article, could it comment this?

specimens of Pterosauria (Reptilia) with soft partes with implications
