Osteohistological signal from the smallest known phytosaur femur reveals slow growth and new insights into the evolution of growth in Archosauria

open access: yesJournal of Anatomy, EarlyView.
The paucity of small, skeletally immature individuals representing the earliest ontogenetic stages of extinct archosaurs complicates our understanding of the growth dynamics within and between species. The opportune finding of the smallest phytosaur femora reveals slow growth, a surprising signal considering that larger phytosaurs in North America have

The hearing capabilities of the Dromornithidae (Aves), with inferences on acoustic communication and ecology

open access: yesJournal of Anatomy, EarlyView.
The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

Ontogenetic Tooth Reduction in Stenopterygius quadriscissus (Reptilia: Ichthyosauria): Negative Allometry, Changes in Growth Rate, and Early Senescence of the Dental Lamina

open access: yesPLoS ONE, 2015
We explore the functional, developmental, and evolutionary processes which are argued to produce tooth reduction in the extinct marine reptile Stenopterygius quadriscissus (Reptilia: Ichthyosauria). We analyze the relationship between mandible growth and
