Research Interests

SydneyMohrI am a M.Sc. student with a primary interest in birds and their fossil representatives. Being a bird watcher and photographer for several years, my current research involves comparing the jaws and teeth in fossil birds and closely related non-avian theropods, particularly Troodontids and Dromaeosaurs. My goal is to assess the similarities and differences in tooth development and eruption with the purpose of understanding the evolution of tooth loss in birds. Thin-sections of bird and non-avian theropod teeth show distinct growth lines which can be used to assess the rate of development within the jaw. In addition, examining internal jaw anatomy and associated implantation of the teeth of birds may reveal overall changes associated with the onset of edentulism, as well as offer insight on the evolutionary relationships between birds and their non-avian theropod ancestors.

I hold a BA in Ancient and Medieval History with a minor in Latin from the University of Calgary, and after graduating switched over into the Geosciences. As a Geology major, I researched the origins of a set of unique volcanic cliff formations in the Hawaiian Islands, in addition to assisting with an undergraduate project studying an unusual flood deposit on the Red Deer River in Alberta.

I am also an artist and illustrator working mainly on the life reconstruction of fossil organisms. My work has appeared primarily in published research and science papers, as well as in online courses and museum exhibits.
