Skull 3D images of a Rhinella pygmaea specimen scanned with distinct filters. Several R. pygmaea specimens presented transparency in some bones, such as the squamosal, sphenethmoid and the parasphenoid bones, making the precise determination of sutures between these bones difficult (indicated by the arrows). Scanning with a thinner filter corrects for this problem as can be seen in c and d. a Dorsal view of a skull scanned with an aluminum filter 1.0 mm (AL1.0); b) Ventral view of the same skull scanned with AL1.0; c) Dorsal view of the same skull scanned with an aluminum filter 0.5 mm (AL0.5); d) Ventral view of the same skull scanned with AL0.5
