Rb-Sr Radiometric Dating of Rocky Planetary Bodies via LA-ICPMS
(2021)
Constraining ages of surface features on rocky objects in the Solar System provides fundamental insights about the flux of impactors through time (including the putative Late Heavy Bombardment), rates of tectonic and ...
Targeting the spatial context of obesity determinants via multiscale geographically weighted regression
(Springer Nature, 2020-04-05)
Obesity rates are recognized to be at epidemic levels throughout much of the world, posing significant threats to both the health and financial security of many nations. The causes of obesity can vary but are often complex ...
Investigating the Internal Structure of Earth and Mars with Seismic Body Waves
(2020)
Seismic waves propagating through the interior of planetary bodies arepowerful imaging tools for revealing a high-resolution picture of their internal
structures. Owing to the abundant seismic data on Earth, seismology has ...
Crystallization histories of the group IIF iron meteorites and Eagle Station pallasites
(Wiley - Meteoritics & Planetary Science, 2020)
The group IIF iron meteorites and Eagle Station pallasites (PES) have highly siderophile element abundances (HSE; Re, Os, Ir, Ru, Pt, and Pd) of metal that are consistent with formation in planetesimal cores by fractional ...
Theropod guild structure and the tyrannosaurid niche assimilation hypothesis: implications for predatory dinosaur macroecology and ontogeny in later Late Cretaceous Asiamerica.
(Canadian Science Publishing, 2021-06-17)
Well-sampled dinosaur communities from the Jurassic through the early Late Cretaceous show greater taxonomic diversity among larger (>50 kg) theropod taxa than communities of the Campano-Maastrichtian, particularly to those ...
Evaluating the ecology of Spinosaurus: Shoreline generalist or aquatic pursuit specialist?
(Coquina Press, 2021-01)
The giant theropod Spinosaurus was an unusual animal and highly derived in many ways, and interpretations of its ecology remain controversial. Recent papers have added considerable knowledge of the anatomy of the genus ...
The fast and the frugal: Divergent locomotory strategies drive limb lengthening in theropod dinosaurs
(2020-05-13)
Limb length, cursoriality and speed have long been areas of significant interest in theropod paleobiology, since locomotory capacity, especially running ability, is critical in the pursuit of prey and to avoid becoming ...
Comment on: Aquatic adaptation in the skull of carnivorous dinosaurs (Theropoda: Spinosauridae) and the evolution of aquatic habits in spinosaurids. 93: 275–284
(2022-06)
In a recent paper, the contention that spinosaurine theropods were semi-aquatic was supported by Arden et al., (2019) and they provided a hypothetical sequence of acquisition of traits that had evolved in line with this ...
Meter-Scale Chemical and Isotopic Heterogeneities in the Oceanic Mantle, Leka Ophiolite Complex, Norway
(Oxford, 2021-07-13)
Mantle peridotites from three 3 x 3-meter grids sampled at kilometer distances from one another in the ca. 497 Ma Leka Ophiolite Complex (LOC), Norway, are examined to investigate the chemical and isotopic nature of oceanic ...
Earth's Radiogenic Heat Production and the Composition of the Deep Continental Crust
(2022)
Much of the continental crust, the 40+ km thick plates of rock that make up the outer shell of our planet, is inaccessible to us living on its surface. Thus its composition is a mystery. We lack the technology to sample ...
