Developmental traits and life strategy of redlichiid trilobites. [PDF]
Biol Rev Camb Philos Soc, 2023 ABSTRACT The developmental mode of four redlichiid trilobites is summarized, based upon exceptionally well‐preserved, articulated specimens from Cambrian Series 2 (stages 3 and 4) strata in southwestern China and South Australia. These relatively complete developmental sequences indicate a balanced rate in segment increase and addition to the thorax ...

Palaeontology, Volume 66, Issue 2, March/April 2023., 2023 Abstract Trilobites are an abundant group of Palaeozoic marine euarthropods that appear abruptly in the fossil record c. 521 million years ago. Quantifying the development of morphological variation (or ‘disparity’) through time in fossil groups like trilobites is critical in understanding evolutionary radiations such as the Cambrian ‘explosion’. Here,

Papers in Palaeontology, Volume 7, Issue 3, Page 1657-1698, August 2021., 2021 Abstract New, accurately located and well‐preserved agnostid trilobite material has been collected from the type locality of the Drumian (middle Cambrian, Miaolingian) Manuels River Formation, Newfoundland, Canada. The well‐exposed grey to black shales containing the fauna were deposited on the former microcontinent Avalonia.

Phylogenetic response of naraoiid arthropods to early–middle Cambrian environmental change
Palaeontology, Volume 64, Issue 1, Page 161-177, January 2021., 2021 Abstract The Cambrian Period, primarily known for animal life diversifying, experienced global extinctions. Pulses of extinction in Cambrian Series 2 are exemplified by the disappearance of archaeocyath sponges and olenelline and redlichiid trilobites.

The fossil record of ecdysis, and trends in the moulting behaviour of trilobites [PDF]
, 2016 Ecdysis, the process of moulting an exoskeleton, is one of the key characters uniting arthropods, nematodes and a number of smaller phyla into Ecdysozoa.
