MPUM 7039: a pterosaur sternal complex?

Figure 1. MPUM 7039, an isolated Triassic pterosaur sternal complex with parts colorized. The shape is very much like that of Eudimorphodon.

Figure 1. MPUM 7039, an isolated Triassic pterosaur sternal complex with parts colorized. The shape is very much like that of Eudimorphodon (MCSNB 2888) and would have belonged to a powerful flapping flyer with large chest muscles anchored here. This is about 3x life-size at the 72dpi of your monitor screen.

Yes!
MPUM 7039, identified by Dalla Vecchi 2003 as a “relatively large, incomplete and isolated sternal plate “prudently consider it as cf. Eudimorphodon” is indeed that.

Of course, as well all know, a sternal complex includes the interclavicle and clavicles along with the sternal plate, here (Fig. 1) colorized for easy identification. Let’s keep calling this a sternal complex because it’s not just a sternum and sometimes the sternal portion is the smallest part.

This post is part of a Triassic series that follows an earlier one on a gastric pellet containing a pterosaur.
