Per Ahlberg

Per Ahlberg is a Professor at Uppsala University's Department of Organismal Biology, specializing in vertebrate evolution and paleontology. His research focuses on early vertebrates, particularly Devonian tetrapods, placoderms, and the transition from fish to land vertebrates. He employs advanced imaging techniques like synchrotron tomography to study fossil anatomy and preservation.

Key areas of study include the evolution of jaws, teeth, and skeletal structures in early vertebrates, as well as the ecological and environmental contexts of major evolutionary transitions. His work integrates anatomical, paleontological, and developmental approaches, collaborating on projects such as the analysis of the Gogo Lagerstätte fossils and the study of tetrapod trackways.

Ahlberg's publications highlight contributions to understanding vertebrate origins, such as discoveries related to Romundina stellina and Ventastega curonica, which bridge gaps between fish and tetrapods. He has also addressed broader topics like fossil nomenclature stability and post-extinction ecosystem recovery.
