Andrew Jones is undertaking doctoral research into the morphological convergence found between phytosaurs (approx 230-200 million years ago) and a range of modern and fossil crocodilian taxa, often purported to have filled the ecological niche left vacant by the demise of Phytosauria.
He is using a variety of functional, morphological and cladistic techniques to investigate the relationships between phytosaur taxa, and their functional biology to draw inferences regarding their role within the wider ecosystem.
