  • Alveoli, teeth, and tooth loss: Understanding the homology of internal mandibular structures in mysticete cetaceans 
    Peredo, Carlos Mauricio; Pyenson, Nicholas D.; Uhen, Mark D.; Marshall, Christopher D. (2017)
    The evolution of filter feeding in baleen whales (Mysticeti) facilitated a wide range of ecological diversity and extreme gigantism. The innovation of filter feeding evolved in a shift from a mineralized upper and lower ...
  • The apparent exponential radiation of Phanerozoic land vertebrates is an artefact of spatial sampling biases 
    Close, Roger A.; Benson, Roger B. J.; Alroy, John; Carrano, Matthew T.; Cleary, Terri J.; Dunne, Emma M.; Mannion, Philip D.; Uhen, Mark D.; Butler, Richard J. (2020)
    There is no consensus about how terrestrial biodiversity was assembled through deep time, and in particular whether it has risen exponentially over the Phanerozoic. Using a database of 60 859 fossil occurrences, we show ...
  • A cranial correlate of body mass in proboscideans 
    Jukar, Advait M.; Lyons, S. Kathleen; Uhen, Mark D. (2018)
    Allometric scaling relationships are often used to estimate the body mass (BM) of extinct mammalian taxa. For proboscideans, shoulder height or limb bone dimensions have typically been used to estimate BM. However, these ...
  • Diversity dynamics of Phanerozoic terrestrial tetrapods at the local-community scale 
    Close, Roger A.; Benson, Roger B. J.; Alroy, John; Behrensmeyer, Anna K.; Benito, Juan; Carrano, Matthew T.; Cleary, Terri J.; Dunne, Emma M.; Mannion, Philip D.; Uhen, Mark D.; Butler, Richard J. (2019)
    The fossil record provides one of the strongest tests of the hypothesis that diversity within local communities is constrained over geological timescales. Constraints to diversity are particularly controversial in modern ...
  • Effects of allometry, productivity and lifestyle on rates and limits of body size evolution 
    Okie, Jordan G.; Boyer, Alison G.; Brown, James H.; Costa, Daniel P.; Ernest, S. K. Morgan; Evans, Alistair R.; Fortelius, Mikael; Gittleman, John L.; Hamilton, Marcus J.; Harding, Larisa E.; Lintulaakso, Kari; Lyons, Sara K.; Saarinen, Juha J.; Smith, Felisa A.; Stephens, Patrick R.; Theodor, Jessica; Uhen, Mark D.; Sibly, Richard M. (2013)
    Body size affects nearly all aspects of organismal biology, so it is important to understand the constraints and dynamics of body size evolution. Despite empirical work on the macroevolution and macroecology of minimum and ...
  • The Evolution of Maximum Body Size of Terrestrial Mammals 
    Smith, Felisa A.; Boyer, Alison G.; Brown, James H.; Costa, Daniel P.; Dayan, Tamar; Ernest, S. K. Morgan; Evans, Alistair R.; Fortelius, Mikael; Gittleman, John L.; Hamilton, Marcus J.; Harding, Larisa E.; Lintulaakso, Kari; Lyons, Sara K.; McCain, Christy; Okie, Jordan G.; Saarinen, Juha J.; Sibly, Richard M.; Stephens, Patrick R.; Theodor, Jessica; Uhen, Mark D. (2010)
    The extinction of dinosaurs at the Cretaceous/Paleogene (K/Pg) boundary was the seminal event that opened the door for the subsequent diversification of terrestrial mammals. Our compilation of maximum body size at the ...
  • First record of the archaeocete whale family Protocetidae from Europe 
    Uhen, Mark D.; Berndt, Hans-Juergen (2008)
    We describe a specimen of Eocetus sp. from the middle Eocene Stockletten Formation of Rohrdorf, Bavaria, Germany, consisting of a lumbar vertebral body and transverse processes. This specimen constitutes the first record ...
  • From Card Catalogs to Computers: Databases in Vertebrate Paleontology 
    Uhen, Mark D.; Barnosky, Anthony D.; Bills, Brian; Blois, Jessica; Carrano, Matthew T.; Carrasco, Marc A.; Erickson, Gregory M.; Eronen, Jussi T.; Fortelius, Mikael; Graham, Russell W.; Grimm, Eric C.; O'Leary, Maureen A.; Mast, Austin; Piel, William H.; Polly, P. David; Saila, Laura K. (2013)
    Data, whether images, measurements, counts, occurrences, or character codings, are a cornerstone of vertebrate paleontology. Every published paper, master's thesis, and doctoral dissertation relies on these data to ...
  • Late Quaternary extinctions in the Indian Subcontinent 
    Jukar, Advait M.; Lyons, Sara K.; Wagner, Peter J.; Uhen, Mark D. (2021)
  • Lateral palatal foramina do not indicate baleen in fossil whales 
    Peredo, Carlos Mauricio; Pyenson, Nicholas D.; Uhen, Mark D. (2022)
    Today's mysticetes filter-feed using baleen, a novel integumentary structure with no apparent homolog in any living mammal. The origins of filter-feeding and baleen can be informed by the fossil record, including rare ...
  • Marine mammals from the Miocene of Panama 
    Uhen, Mark D.; Coates, Anthony G.; Jaramillo, Carlos A.; Montes, Camilo; Pimiento, Catalina; Rincon, Aldo; Strong, Nikki; Velez-Juarbe, Jorge (2010)
  • The maximum rate of mammal evolution 
    Evans, Alistair R.; Jones, David; Boyer, Alison G.; Brown, James H.; Costa, Daniel P.; Ernest, S. K. M.; Fitzgerald, Erich M. G.; Fortelius, Mikael; Gittleman, John L.; Hamilton, Marcus J.; Harding, Larisa E.; Lintulaakso, Kari; Lyons, Sara K.; Okie, Jordan G.; Saarinen, Juha J.; Sibly, Richard M.; Smith, Felisa A.; Stephens , Patrick R.; Theodor, Jessica M.; Uhen, Mark D. (2012)
    How fast can a mammal evolve from the size of a mouse to the size of an elephant? Achieving such a large transformation calls for major biological reorganization. Thus, the speed at which this occurs has important implications ...
  • A New Kentriodontid (Cetacea: Odontoceti) from the Early Miocene Astoria Formation and a Revision of the Stem Delphinidan Family Kentriodontidae 
    Peredo, Carlos Mauricio; Uhen, Mark D.; Nelson, Margot D. (2018)
    The Family Kentriodontidae is a diverse and abundant group of odontocetes from the late Oligocene and Miocene around the globe. Despite nearly a century of research on the group, the relationships across the family have ...
  • New Middle Eocene Whales from the Pisco Basin of Peru 
    Uhen, Mark D.; Pyenson, Nicholas D.; Devries, Thomas J.; Urbina, Mario; Renne, Paul R. (2011)
  • Patterns of maximum body size evolution in Cenozoic land mammals: eco-evolutionary processes and abiotic forcing 
    Saarinen, Juha J.; Boyer, Alison G.; Brown, James H.; Costa, Daniel P.; Ernest, S. K. Morgan; Evans, Alistair R.; Fortelius, Mikael; Gittleman, John L.; Hamilton, Marcus J.; Harding, Larisa E.; Lintulaakso, Kari; Lyons, Sara K.; Okie, Jordan G.; Sibly, Richard M.; Stephens, Patrick R.; Theodor, Jessica; Uhen, Mark D.; Smith, Felisa A.

  • Tooth Loss Precedes the Origin of Baleen in Whales 
    Peredo, Carlos Mauricio; Pyenson, Nicholas D.; Marshall, Christopher D.; Uhen, Mark D. (2018)
    Whales use baleen, a novel integumentary structure, to filter feed; filter feeding itself evolved at least five times in tetrapod history but demonstrably only once in mammals 1]. Living baleen whales (mysticetes) are born ...
