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 3D model of the humerus was created from an isolated element that is referred to the pterosaur Arambourgiania philadelphiae. The element is accessioned to Yarmouk University (YUPC-RUSEIFA-1) in the Hashemite Kingdom of Jordan. The specimen was collected from Late Cretaceous-aged sediments at the Ruseifa Quarry in central Jordan. For inquiries about access to the specimen, please contact Jeff Wilson Mantilla (  wilsonja@umich.edu) or Iyad Zalmout ( izalmout@ksu.edu.sa). Casts of this element of Arambourgiania are available at the University of Michigan Museum of Paleontology.
