    ..Fossils of one of the oldest relatives to baleen-bearing whales have been described from Antarctica. Aspects of its anatomy cast doubt on conventional views for the evolution of filter-feeding and body size in whales. ..
  2. Geisler J, Boessenecker R, Brown M, Beatty B. The Origin of Filter Feeding in Whales. Curr Biol. 2017;27:2036-2042.e2 pubmed publisher
    ..When placed in a phylogenetic context, our new taxon indicates that filter feeding was preceded by raptorial feeding and that suction feeding evolved separately within a clade removed from modern baleen whales. ..
  3. Geisler J. Evolution: Hearing and Feeding in Fossil Whales. Curr Biol. 2017;27:R596-R598 pubmed publisher
    ..The evolution of whales marks one of the major transitions in the history of mammals. Two new studies provide key insights into the evolution of hearing specializations and feeding strategies in early whales. ..

    ..Our trees also imply that many character states shared by river dolphins evolved in their oceanic ancestors, contradicting the hypothesis that these characters are convergent adaptations to fluvial habitats. ..
