Functional traits of fossil plants

Led by Prof. McElwain, the ERC-funded TERRAFORM project team recently published a comprehensive review “Functional Traits of Fossil Plants” in the New Phytologist. The review took a unique approach, evaluating which extant plant traits offer the greatest promise for application to fossils through contemporary trait-based ecology. The focus was placed on plant functional traits and measurable properties of fossils that provide insights into the functioning of the plants in past environments.

Taking into consideration the limitations of a trait-based approach in palaeobotany, the team together with collaborators assessed over 30 extant traits in palaeobotany and ranked 26 paleo-functional traits based on taphonomic and methodological criteria that can potentially impact Earth system processes. The Tansley Review offers a new perspective on the study of extinct plants and brings insights into their functioning in the past.
