Decoupling of taxonomic and ecologic severity of Phanerozoic marine mass extinctions
TL;DR: This paper used a system of paleoecological levels that allows for the ranking of ecological degradation or shifts associated with significant taxonomic events, along with an analysis of large-scale paleoenvironmental patterns of two of the great evolutionary faunas, to compare the relative ecologic degradation caused by two major mass extinctions.

Vertebrate Burrow Complexes from the Early Triassic Cynognathus Zone (Driekoppen Formation, Beaufort Group) of the Karoo Basin, South Africa
TL;DR: A scratch-marked trirachodon burrow complex with multiple branching tunnels and terminal chambers was excavated from the Lower Triassic Driekoppen Formation, northeastern Free State, South Africa.

The Cosmic Zoo: The (Near) Inevitability of the Evolution of Complex, Macroscopic Life
TL;DR: In this article, the authors identify various major key innovations, and use an analytical toolset consisting of a set of models to analyse how likely each key innovation is to occur, and conclude that if the origin of life can occur rather easily, we should live in a cosmic zoo, as the innovations necessary to lead to complex life will occur with high probability given sufficient time and habitat.

Strategy for modeling putative multilevel ecosystems on Europa.
TL;DR: Two alternative biospheres beneath the ice surface of Europa are modeled, based on analogous ecosystems on Earth in potentially comparable habitats, with reallocation of biomass quantities consistent with different sources of energy and chemical constituents.
The Cosmic Zoo: The (Near) Inevitability of the Evolution of Complex, Macroscopic Life
TL;DR: Various major key innovations are identified, and an analytical toolset consisting of a set of models to analyse how likely each key innovation is to occur is used, finding that once the origin of life is accomplished, most of the key innovations can occur rather readily.
