A possible case of inverted lifestyle in a new bivalved arthropod from the Burgess Shale [PDF]
Royal Society Open Science, 2019 The origin of the arthropod carapace, an enlargement of cephalic tergites, can be traced back to the Cambrian period. However, its disparity and evolution are still not fully understood.

A comprehensive Cambrian correlation chart
, 2020 The International Subcommission on Cambrian Stratigraphy has introduced a number of internal subdivisions (i.e., series and stages), but most of the explanatory publications lack reliable data on the correlation between all Cambrian key continents.

A modified trap design for sampling subterranean habitats for central Texas Eurycea salamanders [PDF]
Subterranean BiologyIn this paper, we describe modifications to a sampling technique for surface, stream-dwelling salamanders for use in subterranean settings. Leaf litter bags are an effective and commonly used trap for salamanders, and their construction purposefully ...

Morphology and relationships of the enigmatic stenothecoid pan-brachiopod Stenothecoides—new data from the middle Cambrian Burgess Shale Formation [PDF]
Acta Palaeontologica Polonica, 2021 Bulk sampling of middle Cambrian carbonate units in the lower Burgess Shale Formation (Wuliuan) and the upper Wheeler Formation (Drumian) in Utah have yielded abundant silicified stenothecoids.

On the Topology of the Cambrian Semilattices [PDF]
, 2012 For an arbitrary Coxeter group $W$, David Speyer and Nathan Reading defined Cambrian semilattices $C_{\gamma}$ as semilattice quotients of the weak order on $W$ induced by certain semilattice homomorphisms.

New artiopodan euarthropods from the Chengjiang fauna (Cambrian, Stage 3) at Malong, Yunnan, China [PDF]
Acta Palaeontologica Polonica, 2023 The artiopodans, consisting of trilobites and their relatives, were a major euarthropod group in the Paleozoic. Since the first discovery of Naraoia from the Chengjiang fauna, a significant number of artiopodans have been subsequently found in China ...

An encrusting kleptoparasite-host interaction from the early Cambrian
Nature Communications, 2020 Parasite–host systems are pervasive in nature but are extremely difficult to convincingly identify in the fossil record. Here we report quantitative evidence of parasitism in the form of a unique, enduring life association between tube-dwelling organisms
