FEST: 'Ultrastructural insights into early vertebrate biomineralization and ecology'
Friday Earth Sciences Talk
Dr Emilia Jarochowska: 'Ultrastructural insights into early vertebrate biomineralization and ecology'.
As soft tissues rarely preserve in the geological record, fossil skeletons are the primary source of information on the evolution. The development of a mineralized skeleton has been one of the key evolutionary innovations and allowed organisms to spread into new niches. But first vertebrate skeletons were somewhat unimpressive: microscopic scales and teeth. Can we reconstruct their mechanical properties to learn if they were used by predators to capture prey? Can we tell what dietary niches they occupied? Or whether they invaded land?
In this talk, I will take you for a journey through the early evolution of phosphatic biomineralization and how its study can benefit from methods borrowed from structural geology and material sciences.
Emilia Jarochowska recently joined the Department of Earth Sciences at UU. She is appointed as assistant professor per October 1st.
With the Friday Earth Sciences Talks (FEST) we intend to bring the departments of Earth Sciences and Physical Geography together. The aim is to present (mostly) Utrecht-based Earth Sciences in an accessible way in order to stay familiar with each other鈥檚 work across disciplines. Alumni and students are also invited, in particular MSc students in Earth Sciences. Free access and no pre-registration.
