Schizophoria iowensis

Rhynchonelliform (=articulated) brachiopods comprised a dominant component of Paleozoic shallow marine ecosystems. Because fossil brachiopods are numerically abundant, well-preserved, and relatively easy to identify, they are an ideal clade to study for paleobiogeographic and paleoecological analyses, such as PaleoENM and dispersal analyses.  Thus, much of our work focuses on fossil brachiopods as a model clade for examining faunal level patterns.

Unfortunately, only a limited subset of fossil brachiopods have been analyzed phylogenetically.  Many of the techniques used in the lab, such as phylogenetic biogeography and speciation analysis, require a phylogenetic hypothesis. Consequently, many of our studies involve phylogenetic analyses of representative taxa within the biota.

Also, we just love brachiopods!

In the distant past, I also constructed phylogenies for arthropods and once (gasp) even a bivalve clade:
