Vertebrate Evolutionary Morphology in Tübingen

We are interested in evolutionary vertebrate morphology with a focus on reptiles and mammals. We study, using traditional histological and gross anatomical approaches, the interrelationship of ontogenetic and phylogenetic patterns within a modern conceptual and analytical framework. For that, we follow a holistic organism concept dealing with extant adult, fossil, and embryonic material. Specifically, we observe the sequence of ontogenetic features, variation, and the homology of adult and developmental structures. The latter include the chondrocranium, head and neck musculature, skull anatomy, and postcranial features. Many studies deal with turtles, lizards, and mammals in general.

Our research topics

Temporal skull region in tetrapods

Using Anatomical Network Analyses (AnNA), Finite Element Analyses (FEAs), classical morphological comparisions and phylogenetic methods, we investigate the evolution, mechanistics, and development of the temporal skull region in land vertebrates. We are interested in how and why temporal openings have evolved.

Feeding related morphology in land vertebrates

Jaw musculature, tendons, and related skeletal structures are analyzed in a comparative anatomical and a biomechanical manner.

Craniogenesis

We study the development of the vertebrate skull using traditional histological techniques as well as modern µCT and FEA technologies.

Turtle neck and head

Neck mobility has great influence on the shape of the turtle skull. We proposed the hypothesis that the increased neck mobility in turtles resulted in the closure of the temporal region in the (likely diapsid) stem turtles and secondarily shaped the resulting anapsid skull of more crownward turtle taxa.

Comparative organogenesis in vertebrates

Heterochrony plays a major role in evolution. Changes in the timing of organ development (external and internal organs, incl. skeleton) are analyzed using the Continuous Analyses. A "Standard Event System to Study Vertebrate Embryos" was introduced to quantitatively study homologous structures in ontogeny (Werneburg 2009). Using this approach a number of vertebrate species are described and phylogenetically analyzed.

Paleontology Collection in Tübingen

As a group housed in the amazing Paleontological Collection in Tübingen/Germany, we conduct research in the history.

Sauropodomorph fauna in Europe

Tübingen Paleontological Collection has a valuable historical sample of early sauropodomorph material collected by Friedrich August Quenstedt and Friedrich von Huene. We study this material with modern taxonomic and phylogenetic approaches.

Locomotion in terrestrial and secondarily aquatic tetrapods

Using embryonic data as well as X-ray and Anatomical Network approaches, we study the functional anatomy, evolution, and devevelopment of various aspects of tetrapod axial and paraxial locomotion.
