CT data and 3D models of phocoenid periotic and bony labyrinth (CCNHM 1913)

High-resolution computed tomography (CT) scan data and 3D digital model of
the periotic bone from phocoenid (porpoise) fossil specimen CCNHM 1913,
and 3D digital model of bony labyrinth extracted from the interior of the
periotic. The dataset includes raw CT scan images (TIFF stack) with
scanning parameters and voxel size information, plus processed 3D models
of the complete periotic and isolated bony labyrinth in STL format. The
periotic bone houses the inner ear structures critical for understanding
hearing capabilities, phylogenetic relationships, and evolutionary
adaptations in cetacean fossils. These digital models enable detailed
morphometric analyses and comparative studies without handling the
original specimen, supporting research in marine mammal evolution,
echolocation, and inner ear morphology.
