The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals
- Maureen A. OLeary, J. Bloch, +20 authors Andrea L. Cirranello
- Biology, Medicine
- Science
- 8 February 2013
Let There Be Mammals The timing of the evolution and radiation of placental mammals and their most recent common ancestor has long been debated, with many questions surrounding the relationships of… Expand
Transient Floral Change and Rapid Global Warming at the Paleocene-Eocene Boundary
- S. Wing, G. Harrington, F. Smith, J. Bloch, D. M. Boyer, K. Freeman

Rapid global warming of 5° to 10°C during the Paleocene-Eocene Thermal Maximum (PETM) coincided with major turnover in vertebrate faunas, but previous studies have found little floral change. Plant… Expand
New Paleocene skeletons and the relationship of plesiadapiforms to crown-clade primates
- J. Bloch, M. Silcox, D. Boyer, E. Sargis
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 23 January 2007
Plesiadapiforms are central to studies of the origin and evolution of primates and other euarchontan mammals (tree shrews and flying lemurs). We report results from a comprehensive cladistic analysis… Expand
Grasping Primate Origins
The evolutionary history that led to Eocene-and-later primates of modern aspect (Euprimates) has been uncertain. We describe a skeleton of Paleocene plesiadapiformCarpolestes simpsoni that includes… Expand
Affinities of ‘hyopsodontids’ to elephant shrews and a Holarctic origin of Afrotheria
- Shawn P. Zack, T. Penkrot, J. Bloch, K. Rose
- Biology, Medicine
- Nature
- 24 March 2005
Macroscelideans (elephant shrews or sengis) are small-bodied (25–540 g), cursorial (running) and saltatorial (jumping), insectivorous and omnivorous placental mammals represented by at least 15… Expand
Giant boid snake from the Palaeocene neotropics reveals hotter past equatorial temperatures
- J. Head, J. Bloch, +5 authors C. A. Jaramillo
- Biology, Medicine
- Nature
- 5 February 2009
The largest extant snakes live in the tropics of South America and southeast Asia where high temperatures facilitate the evolution of large body sizes among air-breathing animals whose body… Expand
Semicircular canal system in early primates.
Mammals with more rapid and agile locomotion have larger semicircular canals relative to body mass than species that move more slowly. Measurements of semicircular canals in extant mammals with known… Expand
Systematics and Biogeography of Crocodylians from the Miocene of Panama
- Alexander K. Hastings, J. Bloch, C. Jaramillo, A. Rincon, B. MacFadden
- Biology
- 1 March 2013
ABSTRACT
Despite the fact that fossil crocodylians have been recovered from the Panama Canal Zone starting with initial excavations in 1912, detailed studies have been lacking. Recent excavations… Expand
Intrinsic hand proportions of euarchontans and other mammals: implications for the locomotor behavior of plesiadapiforms.

- Journal of human evolution
- 1 August 2008
Arboreal primates have distinctive intrinsic hand proportions compared with many other mammals. Within Euarchonta, platyrrhines and strepsirrhines have longer manual proximal phalanges relative to… Expand
