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

Upper lower Cambrian (provisional Cambrian Series 2) trilobites from northwestern Gansu Province, China [PDF]
Upper lower Cambrian (provisional Cambrian Series 2) trilobites are described from three sections through the Shuangyingshan Formation in the Beishan area, northwestern Gansu Province, China. The trilobite fauna is dominated by eodiscoid and corynexochid

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
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 ...

Abnormal trilobites from the Silurian and Devonian of Europe
Malformed trilobites have been documented in deposits ranging from the Cambrian to the Permian. Continued examination of novel malformed specimens provides insight into how trilobites recovered from injuries, experienced genetic abnormalities, and ...

Distribution of the order Proetida (Trilobita) in Baltoscandian Ordovician strata [PDF]
The trilobite order Proetida forms a minor but important faunal element within the Ordovician strata of Baltoscandia. This review follows the current systematic, taxonomic, and stratigraphical usage and discusses the distribution of these trilobites ...

Three-dimensionally preserved appendages of the early Cambrian trilobite Yunnanocephalus yunnanensis [PDF]
Advances in micro-computed tomography have brought new insights into the non-biomineralized three-dimensional morphologies of various euarthropods from the Chengjiang biota.
