How do new morphological traits evolved and what were the larger consequences of these innovations to biodiversity? To get at this problem my research explores the evolutionary foundations of modern vertebrate anatomy using the fossil record and modern phylogenetic tools. My research looks to the fossils early vertebrates from the Palaeozoic Era (approx. 540 to 250 million years ago) to reconstruct the evolutionary assembly of major features of vertebrate anatomy, such as the skull and jaws, paired appendages, and hard tissues.
