My research focuses mainly on the paleoecology, phylogeny and taphonomy of the extinct eurypterids, also known as “sea scorpions.” They were the largest arthropods ever to exist, and could reach more than 9 feet (3 meters) in total length.

With a phylogeny of the group now more or less in place, I’m studying the paleodistribution and dispersal patterns of eurypterids in a phylogenetic context. I’m trying to figure out what kind of environments eurypterids lived in, and which kinds of special conditions were necessary to preserve the cuticle of eurypterids. I’m also addressing some of the same questions in scorpions and other chelicerate groups.
