Methodology
  • We reconstructed Computed Tomography scans using CT Pro 3D and saved the reconstructions as volume files. We processed volume files using Mimics image processing software (Materialize NV) to visualize the CT slices for segmentation. We then proceeded through the CT slices in intervals from the proximal to distal end of each humerus to capture internal structures using the segmenting tools Lasso, LiveWire, Mask, and Interpolate. For each CT slice, we selected all trabecular bone to add to the Mask, which differentiated the trabecular bone from the matrix. A completely segmented slice displays black air space, gray matrix, and highlighted bone. After each slice was segmented, we scrolled distally and repeated the process on a subsequent slice. In regions where the struts had a dense distribution or complex internal structure, we segmented slice-wise to minimize interpolation. In regions where the trabecular bone was sparse or simple and elongate, we segmented approximately every 10 slices. Once a bone was completely segmented, we used the Interpolate tool, which connects consecutive segmented structures to produce a 3D model that accurately reconstructs the true anatomy.
Description
  • The left humerus is part of an associated skeleton of the pterosaur Inabtanin alarabia, accessioned to Yarmouk University (YUPC-INAB-6-001–010) in the Hashemite Kingdom of Jordan. The specimen was collected from Late Cretaceous-aged sediments near Tal Inab in south-central Jordan, which is 34 km north of the current border with Saudi Arabia. For inquiries about access, please contact Jeff Wilson Mantilla ( wilsonja@umich.edu) or Iyad Zalmout ( izalmout@ksu.edu.sa). Casts of this and other elements of Inabtanin alarabia are available at the University of Michigan Museum of Paleontology.

DESCRIPTION
The right and left humeri are part of an associated skeleton of a pterosaur accessioned to Yarmouk University (YUPC-INAB-6-001–010) in the Hashemite Kingdom of Jordan. The specimen was collected from Late Cretaceous-aged sediments near Tal Inab in south-central Jordan, which is 34 km north of the current border with Saudi Arabia.

FILE LIST
The data set includes 2 three-dimensional models in .ply format; one model is the proximal humerus, and one the distal.
