Shifting spaces: Which disparity or dissimilarity measurement best summarize occupancy in multidimensional spaces?

Ecology and Evolution, Volume 10, Issue 14, Page 7261-7275, July 2020., 2020
Different measurements of multidimensional space occupancy can give different results and are affected by the multidimensional space properties and biological question. This paper provides a guideline of what different measurements are capturing and in which context they can be useful for answering biological questions.

Sequence of post-moult exoskeleton hardening preserved in a trilobite mass moult assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco [PDF]

Acta Palaeontologica Polonica, 2019
Euarthropods have a tough exoskeleton that provides crucial protection from predation and parasitism. However, this is restrictive to growth and must be periodically moulted.

Biostratigraphy and correlation of the Cambrian Series 2 (Stage 4) to Miaolingian (Wuliuan) Thorntonia Limestone, south‐eastern Georgina Basin (Queensland, Australia)

Papers in Palaeontology, Volume 11, Issue 5, September/October 2025.
Abstract The Australian Cambrian stratigraphic record is one of the most complete for any continent. However, there is a general division, with older Cambrian rocks in South Australia (predominantly Terreneuvian, Stage 2 to Miaolingian, Wuliuan) and younger rocks in northern Australia (mostly latest Series 2, Stage 4 and younger), with minimal ...

The evolutionary history of Coleoptera (Insecta) in the late Palaeozoic and the Mesozoic

Systematic Entomology, Volume 49, Issue 3, Page 355-388, July 2024.
Structural transformations of the elytra and abdomen played a major role in the early beetle evolution in the Permian. Polyphaga appear late in the fossil record, with only a few fossils of Elateriformia in the Late Triassic. Several factors were involved in the enormous diversification of beetles in the Cretaceous but evolutionary interactions with ...
