Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice. [PDF]
Biol Rev Camb Philos SocABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Geophysical Monograph Series, Page 435-447., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Micropollutants and the Restructuring of Microbial Resilience in the Anthropocene. [PDF]
Glob Chang BiolAnthropogenic activities continuously introduce diverse micropollutants into environmental systems through multiple pathways, generating an increasingly complex chemical background. Persistent exposure to this chemical complexity may progressively reshape microbial ecosystems, shifting the functional baseline from which microbial communities respond to

A new middle Cambrian trilobite with a specialized cephalon from Shandong Province, North China [PDF]
Acta Palaeontologica Polonica, 2020 Trilobites achieved their maximum generic diversity in the Cambrian, but the peak of morphological disparity of their cranidia occurred in the Middle to Late Ordovician. Early to middle Cambrian trilobites with a specialized cephalon are rare, especially

Trilobite expansion into estuarine environments during the Ordovician radiation [PDF]
Estonian Journal of Earth Sciences, 2023 Trilobites have traditionally been considered fully marine. Through the integration of ichnological, palaeobiological and sedimentological datasets within a sequence-stratigraphic and stratiÂgraphic palaeobiology framework, we challenge this assumption.

Ontogenetic moulting behavior of the Cambrian oryctocephalid trilobite Arthricocephalites xinzhaiheensis [PDF]
PeerJ, 2021 Moulting behaviors in trilobites are a crucial strategy during development. Previous studies have demonstrated inter-and intraspecific variability of moulting behavior in trilobites.

Advances in the Lower Ordovician of the western Iberian Chain, NE Spain [PDF]
Estonian Journal of Earth Sciences, 2023 The western Iberian Chain of NE Spain represents a lateral prolongation of the West Asturian-Leonese Zone. As other proximal sectors fringing NW Gondwana, the chain comprises a conÂformable and continuous FurongianâTremadocian transition, comprising a
