Thank you for always believing in me. ii ACKNOWLEDGMENTS I would like to thank all of the people who helped me collect the specimens for this study, braving the rocks and the waves in the middle of the night: Leigh Ann Boswell, Shannon Evers, and Steffiny Nelson, you were the hard core tako hunters. I am eternally grateful that you sacrificed your evenings to the octopus gods. Also, thank you to David Harrington (best bucket boy), Bert Tanigutchi, Melanie Hutchinson, Christine Ambrosino, Mark Royer, Chelsea Szydlowski, Ily Iglesias, Katherine Livins, James Wood, Seth Ylitalo-Ward, Jessica Watts, and Steven Zubler. This dissertation would not have happened without the support of my wonderful advisor, Dr. Les Watling. Even though I know he wanted me to study a different kind of “octo” (octocoral), I am so thankful he let me follow my foolish passion for cephalopod sexual selection. Also, he provided me with the opportunity to ride in a submersible, which was one of the most magical moments of my graduate career.

  • A New Family of Diprotodontian Marsupials from the Latest Oligocene of Australia and the Evolution of Wombats, Koalas, and Their Relatives (Vombatiformes) Robin M
    www.nature.com/scientificreports OPEN A new family of diprotodontian marsupials from the latest Oligocene of Australia and the evolution of wombats, koalas, and their relatives (Vombatiformes) Robin M. D. Beck1,2 ✉ , Julien Louys3, Philippa Brewer4, Michael Archer2, Karen H. Black2 & Richard H. Tedford5,6 We describe the partial cranium and skeleton of a new diprotodontian marsupial from the late Oligocene (~26–25 Ma) Namba Formation of South Australia. This is one of the oldest Australian marsupial fossils known from an associated skeleton and it reveals previously unsuspected morphological diversity within Vombatiformes, the clade that includes wombats (Vombatidae), koalas (Phascolarctidae) and several extinct families. Several aspects of the skull and teeth of the new taxon, which we refer to a new family, are intermediate between members of the fossil family Wynyardiidae and wombats. Its postcranial skeleton exhibits features associated with scratch-digging, but it is unlikely to have been a true burrower. Body mass estimates based on postcranial dimensions range between 143 and 171 kg, suggesting that it was ~5 times larger than living wombats. Phylogenetic analysis based on 79 craniodental and 20 postcranial characters places the new taxon as sister to vombatids, with which it forms the superfamily Vombatoidea as defned here. It suggests that the highly derived vombatids evolved from wynyardiid-like ancestors, and that scratch-digging adaptations evolved in vombatoids prior to the appearance of the ever-growing (hypselodont) molars that are a characteristic feature of all post-Miocene vombatids. Ancestral state reconstructions on our preferred phylogeny suggest that bunolophodont molars are plesiomorphic for vombatiforms, with full lophodonty (characteristic of diprotodontoids) evolving from a selenodont morphology that was retained by phascolarctids and ilariids, and wynyardiids and vombatoids retaining an intermediate selenolophodont condition.
