Re: new papers in Acta Geologica Sinica: Ningchengopterus

1. spend more time delineating the skull and other elements, rather than calling it quits after simply broadly outlining of the resulting roadkill.

I haven't seen the paper, but usually specimens from such laminated rocks are not merely roadkills. They are roadkills that have been split down the middle! Through the bones in many cases! This means the bone surfaces are still stuck in the matrix, facing away from you, and that makes even the sutures difficult to trace.
