Research Statement

MMy research interests focus on evolutionary processes and patterns underlying the morphological, taxonomic, and ecological diversity and disparity of Jurassic cartilaginous and ray-finned fishes. Current research projects of mine aim on Early and Late Jurassic fishes from northern Central Europe.
Late Early Jurassic fishes (Chondrichthyes, Teleostei) from northeastern Germany
This project focuses on a previously undescribed marginal marine fish assemblage from the late Pliensbachian of Grimmen, NE Germany, comprising isolated chondrichthyan (Hybodontiformes, Neoselachii, Holocephali) remains and a rich assemblage of teleostean otoliths.
One of the main emphases of this project is to provide detailed morphological descriptions and taxonomic discussions for each chondrichthyan species presented in the fossil assemblage, and to place them into their appropriate palaeoecological context for better understanding the taxonomic and ecological diversity of Early Jurassic chondrichthyans. In addition, previously presented hypotheses on Early and Middle Jurassic elasmobranch diversity and biogeography patterns will be tested by using different mathematical methods.
The second emphasis of this project is to describe the teleostean otoliths in detail, and to compare them to existing Jurassic otolith-based teleostean taxa, but also to species described based on skeletons with otoliths in situ. The data derived from this work will serve to add to the ´Pliensbachian gap´ in our understanding of Early Jurassic teleostean diversity.

Late Jurassic fishes (Elasmobranchii, Actinopterygii) from northwestern Poland
This project is focusing on a largely undocumented fossil fish assemblage recovered from early Kimmeridgian marine strata of Czarnoglowy, NW Poland, including a rich and diverse assemblage of isolated remains referable to hybodontiform and neoselachian elasmobranchs, as well as pycnodontiform and ginglymodian actinopterygians. The aim of this project is to analyze the taxonomic composition of the fossil ichthyofauna recovered from the Late Jurassic of Czarnoglowy and to compare it to those reported from other Late Jurassic European localities in order to gain deeper insights into palaeobiodiversity, palaeoecology, and palaeobiogeography of fishes during this time interval.
