Matching a fossil plate to a counterplate is easy.
Matching a photo of a plate to a photo of counterplate (Fig. 1) requires Photoshop, even if the differences are minute.
This is the first time I’ve seen
the counterplate to the SMNS 6592 specimen attributed to Germanodactylus. And I think this counterplate is composed of painted plaster. Photoshop was used to match the plate to the counterplate and to trace the resulting elements. As you can see, the pelvis is in an atypical position due to taphonomy (crash landing on its butt?), but everything else seems to be naturally posed with the exception of the displaced and overlapping femora (another results of the crash landing, perhaps).
