Abstract

Understanding the cranial anatomy of long-necked sauropod dinosaurs presents significant challenges due to their complex skull construction, paper-thin bone structures, and rarity of complete fossil specimens. These issues are particularly evident in field research at sites like the Two Sisters Quarry in Big Horn County, Wyoming, where teams from the University of Lynchburg and the Virginia Museum of Natural History seek to identify sauropod skulls. To enhance the interpretive framework for field researchers and educators, this project focuses on producing detailed 3D-printed models of sauropod skulls, specifically designed for anatomical study and educational purposes.

The project involved the selection, manipulation, and 3D printing of high-fidelity sauropod skull models based on scientific research and a CT scanned Smithsonian Diplodocus specimen. Key steps included understanding basic vertebrate cranial anatomy, interpreting sauropod-specific skull features, and overcoming challenges in preparing these intricate models for printing. Techniques in 3D software, such as Flashprint, allowed for careful manipulation and slicing of digital skull models to optimize print efficiency while preserving anatomical detail. Trial and error with printer configurations, filament choices, and support structure setups led to refined printing methods that ensure high-quality results.

Once printed, these models were further enhanced through cleaning, sanding, and painting to emphasize critical anatomical features. The final models, along with an anatomy guide, serve as both teaching tools for lay audiences and field guides for paleontologists, aiding in the identification of rare sauropod skull fragments. This project not only contributes to the understanding of sauropod anatomy but also highlights the potential of 3D printing technology in paleontological research and science education.
