Abstract

MicroCT (x-ray microcomputed tomography, YXLON FF35 CT) dataset of a southern three-banded armadillo or Azara's domed armadillo (Tolypeutes matacus) rolled fully up into a ball. The specimen is part of the mammal collection of the first zoological department of the Natural History Museum Vienna. This specimen was taxidermied in a standing position after the microCT scan.
