Teaching philosophy

Integrative paleobiology intrinsically builds analytical thinking and problem solving skills. Furthermore, the deep-time perspective of this discipline serves as an important pillar within the geosciences and biological sciences. When I teach, I incorporate quantitative, project based exercises to build open these existing strengths. Virtual models and 3D printing regularly appear in my courses and outreach because they provide unprecedented views of the complete morphology of reconstructed animals. These approaches allow specimens to be brought to life, and into the classroom, regardless of rarity, cost, or fragility.

3D printed ammonite (Hoploscaphites crassus microconch) with reconstructed soft body and mouthparts (aptychi)
Peterman trilobite 3D print
3D printed trilobite (Dircranurus monstrosus). Real specimens are somewhat rare, and usually too expensive to include in teaching collections. 
Peterman ammonite suture 3D print
Translucent, 3D printed ammonite (Eopachydiscus marcianus) used to display the full 3D morphology of the structures that create "suture patterns" - a diagnostic character of species that may have served important functions for regulating buoyancy (Peterman et al., 2021, Scientific Reports​).
