The evolution of reproduction in Ediacaran–Cambrian metazoans
Biological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

The Depositional Record, Volume 11, Issue 4, Page 1107-1131, September 2025.Analysing Rare Earth Elements (REEs) and other trace elements together with stable isotope data in poorly preserved belemnites can provide valuable insights into early diagenetic pathways, water‐interaction processes, and even potential redox conditions.

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 ...

An electron backscatter diffraction study of geesops: a broader view of trilobite vision? [PDF]
, 2008 The calcite eyes of trilobites have been studied for over 100 years using methods including light microscopy (e.g. Clarke 1889; Campbell 1975; Towe 1973; Clarkson 1979 and Bruton and Haas 2003) and more recently cathodoluminescence (CL) imaging coupled ...

Ten simple rules to follow when cleaning occurrence data in palaeobiology
Palaeontology, Volume 68, Issue 5, September/October 2025.Abstract Large datasets of fossil occurrences, often downloaded from online community‐maintained databases, are a vital resource for understanding broad‐scale evolutionary patterns, such as how biodiversity has changed through time and space. Such datasets, however, are not infallible and must be ‘cleaned’ of inaccurate, incomplete, or duplicate data ...

Scotland : Hebridean Terrane [PDF]
, 2011 The Cambrian succession in the Hebridean Terrane extends for about 200 km from near Durness on the northern coast of the Scottish mainland SSW to Skye (Fig. 14). The classic account of the whole region is the memoir by Peach et al.

Distribution of the order Proetida (Trilobita) in Baltoscandian Ordovician strata [PDF]
, 2009 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 ...
