A quick look at the original Tapejara skull

Short one today
told mostly in pictures.

Topic: Simplification. 
Get rid of the extraneous data to better see and understand the basics.

Figure 1. Just take out everything that isn't this side of Tapejara. Rearrange the parts for best fit. Make a guess for the missing parts and this is what you get.

In this case
the skull of the original Tapejara fossil (Fig. 1) is trimmed back to just the basics and slightly shifted to fit. Missing tips are added based on phylogenetic bracketing.

Figure 4. Click to enlarge. The Tapejaridae arise from dsungaripterids and germanodactylids.

Figure 2. Click to enlarge. Tiny Tapejaridae arise from dsungaripterids and germanodactylids, then grow larger phylogenetically.

Tapejara wellnhoferi
(Kellner 1989; 108 mya, Early Cretaceous) was immediately recognized as something quite different when first discovered. Compared to other specimens, this one appears to have no sharp premaxilla, likely due to taphonomic loss.
