A Physiologically Explicit Morphospace for Tracheid-based Water Transport in Modern and Extinct Seed Plants

Wilson, Jonathan P.; Knoll, Andrew Herbert (Paleontological Society, 2010)

We present a morphometric analysis of water transport cells within a physiologically explicit three-dimensional space. Previous work has shown that cell length, diameter, and pit resistance govern the hydraulic resistance ...

Non-Skeletal Biomineralization by Eukaryotes: Matters of Moment and Gravity

Raven, John A.; Knoll, Andrew Herbert (Taylor & Francis, 2010)

Skeletal biomineralisation by microbial eukaryotes significantly affects the global biogeochemical cycles of carbon, silicon and calcium. Non-skeletal biomineralisation by eukaryotic cells, with precipitates retained within ...

Geobiology of the Late Paleoproterozoic Duck Creek Formation, Western Australia

Wilson, Jonathan P.; Fischer, Woodward W.; Johnston, David T; Knoll, Andrew Herbert; Grotzinger, John P.; Walter, Malcolm R.; McNaughton, Neal J.; Simon, Mel; Abelson, John; Schrag, Daniel P.; Summons, Roger; Allwood, Abigail; Andres, Miriam; Gammon, Crystal; Garvin, Jessica; Rashby, Sky; Schweizer, Maia; Watters, Wesley A. (Elsevier, 2010)

The ca. 1.8 Ga Duck Creek Formation, Western Australia, preserves 1000 m of carbonates and minor iron formation that accumulated along a late Paleoproterozoic ocean margin. Two upward-deepening stratigraphic packages are ...

Eukaryotic Skeletal Formation

Wallace, Adam F.; Wang, Dongbo; Hamm, Laura M.; Knoll, Andrew Herbert; Dove, Patricia M. (Wiley, 2012)

What is Geobiology?

Knoll, Andrew Herbert; Canfield, Donald E.; Konhauser, Kurt O. (John Wiley & Sons, 2012)

The Fossil Record of Microbial Life

Knoll, Andrew Herbert (Wiley-Blackwell, 2012)

Deep-Water Incised Valley Deposits at the Ediacaran-Cambrian Boundary in Southern Namibia Contain Abundant Treptichnus Pedum

Knoll, Andrew Herbert; Wilson, Jonathan P.; Grotzinger, John P.; Fischer, Woodward W.; Hand, Kevin P.; Jensen, Sören; Abelson, John; Metz, Joannah M.; McLoughlin, Nicola; Cohen, Phoebe A.; Tice, Michael M. (Society for Sedimentary Geology, 2012)

Valley-filling deposits of the Nama Group, southern Namibia, record two episodes of erosional downcutting and backfill, developed close together in time near the Ediacaran-Cambrian boundary. Geochronological constraints ...

Si Isotope Variability in Proterozoic Cherts

Chakrabarti, Ramananda; Knoll, Andrew Herbert; Jacobsen, Stein B.; Fischer, Woodward W. (Meteoritical Society, 2012)

We report Si-isotopic compositions of 75 sedimentologically and petrographically characterized chert samples with ages ranging from ~2600 to 750 Ma using multi-collector inductively coupled plasma mass spectrometry. ...

Ancient Impact and Aqueous Processes at Endeavour Crater, Mars

Knoll, Andrew Herbert; Squyres, S. W.; Arvidson, R. E.; Bell, J. F., III; Calef, F., III; Clark, B. C.; Cohen, B. A.; Crumpler, L. A.; de Souza, P. A., Jr.; Farrand, W. H.; Gellert, R.; Grant, J.; Hurowitz, J. A.; Herkenhoff, K. E.; Johnson, J. R.; Jolliff, B. L.; Li, R.; McLennan, S. M.; Ming, D. W.; Mittlefehldt, D. W.; Parker, T. J.; Paulsen, G.; Rice, M. S.; Ruff, S. W.; Schröder, C.; Yen, A. S.; Zacny, K. (American Association for the Advancement of Science, 2012)

The rover Opportunity has investigated the rim of Endeavour Crater, a large ancient impact crater on Mars. Basaltic breccias produced by the impact form the rim deposits, with stratigraphy similar to that observed at ...

Late Ediacaran Redox Stability and Metazoan Evolution

Knoll, Andrew Herbert; Johnston, David T; Poulton, S. W.; Goldberg, T.; Sergeev, V. N.; Podkovyrov, V.; Vorob’eva, N. G.; Bekker, A. (Elsevier, 2012)

The Neoproterozoic arrival of animals fundamentally changed Earth's biological and geochemical trajectory. Since the early description of Ediacaran and Cambrian animal fossils, a vigorous debate has emerged about the drivers ...
