Research Interests

My research interests focus on addressing the following questions: Is there a relationship between intraspecific variation and directionality of morphological evolution over geological time? What can we learn from studying fossil ontogenies? How do abiotic factors influence the two previous questions – especially the amount and type of meristic (count) variation observed? I am currently studying these sources of variation in marine vertebrates from the Early Jurassic of southwestern Germany.

Exhibitions

2016-2017

The SMNS has one of the largest collections worldwide of fossils from the Posidonia Shale of Holzmaden. However, the depositional conditions resulting in the preservation of these spectacular finds also lead to an abundance of iron sulfide minerals deposited in and around the fossil. When exposed to the atmosphere following excavation, chemical changes begin that can damage and even eventually destroy the fossil. This exhibition focused on both the mineralogy and formation of iron sulfide minerals such as pyrite and marcasite in sedimentary environments, and also the process of fossil conservation and restoration.
