Palaeocast

Found in the fossil record between the Jurassic and the middle Miocene, Notosuchia was a highly diverse and strange group of crocodylomorphs, most notable for their terrestrial lifestyle. Joining us for today’s episode is Dr Yohan Pochat-Cottilloux from the Laboratoire de Géologie de Lyon, who specialises in the study of crocodylomorphs. Together, we will explore the wide range of scientific methodologies that have so far been used to study the lives of these strange reptiles and discuss how they may have looked and behaved.

The field of evolutionary biology has been greatly influenced by the development of modern genetic methodology. The understanding of genes, genomes and the molecular mechanisms key to life on Earth are all goals of evolutionary biology in the 21st century, yet its potential applications seem to be near limitless. Palaeontology and evolutionary biology continue to be closely related and both, with their deeply rooted origins, have been essential to our understanding of macroevolution (major evolutionary change over long periods of time) ever since the major development of the theory in the 19th century. In this episode, Prof. Erica Bree Rosenblum introduces us to this diverse and constantly evolving field. We cover fundamental questions such as: what are genes and genomes and why does understanding them matter; which evolutionary roles do environmental and genetic mechanisms play; and what ultimately causes the rise and fall of species. In order to better understand life on Earth, we show how evolutionary biology brings together the fields of genetics, biochemistry, ecology, palaeontology and more.

In 12 years of podcasting, we have never actually taken the time to address the fundamentals of our field. Such questions could include: what is palaeontology, what is a fossil, how does one become a palaeontologist, and why is palaeontology important? For what should have been our very first episode, we've invited Prof. Roy Plotnick, University of Illinois Chicago, to help us outline everything you need to know about the field of palaeontology. Roy has had a long and varied palaeontological career, he maintains a blog all about the field, and he is author of the book Explorers of Deep Time.

It's been two centuries since the first dinosaur, Megalosaurus, was named by William Buckland and to commemorate the date, the Natural History Museum hosted '200 Years of Dinosaurs: Their Rise, Fall, and Rebirth'. This international conference provides a snapshot of dinosaur research in 2024, demonstrating just how far our understanding of this group has come since 1824. In our coverage of this event, we speak to many of the leading palaeontologists in the field, as we look back over the last 200 years of research and consider what the next 200 might reveal.
