In Review. Grogan, E. D. and R. Lund. Superfetative Viviparity in a Carboniferous Chondrichthyan and Reproduction in Early Gnathostomes. Zoological Journal of the Linnean Society.


I take an integrative approach (fossil and extant) to the study of the origin and relationships of chondrichthyan fishes, and early vertebrates in general.  Emphasis is placed on the functional and developmental morphology of the cranium, suspensorium, mineralized tissues and the immune and vascular systems. Studies in progress involve ontogenetic and phylogenetic differentiation of the cranium, the development and mineralization of skeletal tissues, the description of new Bear Gulch fishes, and phylogenetic and ecomorphological analyses of these Paleozoic fishes.
