Leptodontichthys ziregensis is a newly described eubrachythoracid
arthrodire from the Middle Devonian of Morocco. Only the posterior
superognathal is preserved, it possesses features which were, so far, seen
in Late Devonian forms. The jaw bone presents two sets of teeth, one
lateral and one posterior, with dentinous tissue, pulp cavities and
vascular canals preserved. The CT scans provided here are the ones used
for the study. The complete jaw data was used for the overall study and
the closeup data was used for the segmentation of the teeth. The ply data
is provided to provide the information extracted by the authors during the
study.
The dataset comprises of three .raw files containing the CT slices of the
complete posterior superognathal of Leptodontichthys and a closeup of its
lateral and posterior tooth rows. Each .raw file is accompagnied by a
.xtekVolume text file with all the scan details, including the voxel sizes
of x, y, and z, important for visualising the .raw file in segmentation
software such as mimics or avizo. Ply files of the complete jaw and the
inner structures of its teeth are available and can be opened in a
freeware such as Meshlab. The 3D models (.ply files) of
"Model_Leptodontichthys_Lateral row_dentinous tissue",
"Model_Leptodontichthys_Lateral row_pulp cavities" and
"Model_Leptodontichthys_Lateral row_vascular canals" are
mirrored (vertically). See Readme.txt for additional information
