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

Trilobites of Thailand's Cambrian–Ordovician Tarutao Group and their geological setting
Papers in Palaeontology, Volume 9, Issue 5, September/October 2023., 2023 Abstract Tuff‐bearing upper Cambrian to lowermost Ordovician strata on Ko Tarutao island, Satun province, southernmost peninsular Thailand, contain a rich trilobite fauna relevant to global biostratigraphy, peri‐Gondwanan palaeogeography and shifting evolutionary mode.

Rise and fall of the phacopids: the morphological history of a successful trilobite family
Palaeontology, Volume 66, Issue 5, September/October 2023., 2023 Abstract Phacopidae were a successful family of the Silurian–Devonian period. Although their diversity trends are well identified, their shape evolution is unknown; their morphology often considered to be conservative. We have quantified these morphologies using geometric morphometrics (landmarks) and investigated their evolution using morphological ...

Papers in Palaeontology, Volume 9, Issue 3, May/June 2023., 2023 Abstract Artiopoda was a diverse group of Palaeozoic euarthropods that proliferated in the early Palaeozoic, epitomized by the ubiquitous trilobites. Their possible phylogenetic position outside mandibulates and chelicerates offers the potential for understanding the evolution of euarthropods in more detail.

Palaeontology, Volume 66, Issue 3, May/June 2023., 2023 Abstract Trilobites were notably flexible in the moulting behaviours they employed, producing a variety of moult configurations preserved in the fossil record. Investigations seeking to explain this moulting variability and its potential impacts are few, despite abundant material being available for study.

Richard Maack and his contributions to the botany of Siberia
Nordic Journal of Botany, Volume 2023, Issue 4, April 2023., 2023 A brief account of the biography of Richard Maack (1825–1886) is provided, with an emphasis on his botanical travels and research presented in the context of contemporary politics and sciences. The history of three Siberian expeditions of the Imperial Russian Geographical Society is detailed: to the Viluy River in 1853–1855, to the Amur River in 1855 ...
