Revised phylogenomic analysis and Cretaceous fossil evidence reveal new insights into evolution of Scirtinae (Coleoptera: Scirtidae)

Journal of Systematics and Evolution, EarlyView.
The molecular phylogeny of Scirtinae based on ultraconserved elements is reanalyzed using the site‐heterogeneous model CAT‐GTR+G4. A new scirtine fossil, Serracyphon philipsi gen. et sp. nov., is reported from mid‐Cretaceous Kachin amber, and its placement is evaluated in light of the updated phylogenomic framework of Scirtinae.

Selective sampling of asteroids, the Moon, and Mars: Factors affecting the numerical abundances of members of meteorite groups

Meteoritics &Planetary Science, EarlyView.
Abstract Meteorite collection inventories show that many related meteorite groups have very different numerical abundances (e.g., lunar versus Martian meteorites; Eagle Station pallasites versus main‐group pallasites; eucrites versus diogenites; ungrouped Antarctic irons versus ungrouped non‐Antarctic irons; carbonaceous chondrite‐related (CC) iron ...

Simulating evaporative wet and dry cycles in Gale crater, Mars using thermochemical modeling techniques

Meteoritics &Planetary Science, EarlyView.
Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...

FRAUGHT WITH HIGH TRAGEDY: A CONTEXTUAL AND CHRONOLOGICAL RECONSIDERATION OF THE MAIDEN CASTLE IRON AGE ‘WAR CEMETERY’ (ENGLAND)

Oxford Journal of Archaeology, EarlyView.
Summary The Iron Age ‘war cemetery’ of Maiden Castle hillfort, Dorset, England, is one of the most internationally celebrated of British archaeological discoveries, levels of trauma recorded on skeletons found there being interpreted as evidence for a Roman massacre.
