This study uses μCT to reinterpret the morphology of Lower Cretaceous Cretitanais giganteus. It reveals that C. giganteus has seven pereon tergite, not six, and its alleged chela is a merus of a further posterior leg. These findings make C. giganteus a synonym of the lsopod Urda stemmerbergensis.

The study looks at early cartilaginous fish evolution using Bayesian tip dating methods. It finds that total-group chondrichthyans evolved in the Middle Ordovician and that major acanthodian clades diverged from the stem in quick succession, making this early radiation difficult to resolve

In this paper, the authors specifically look at how stylophoran respiratory structures evolved and determined that the most basal structures did not originate from the same structures that gave rise to gills and oral orifices in other deuterostomes.

Stylophorans are an extinct class of Paleozoic echinoderms with complex morphology. In general, they lack the radial symmetry typical of other echinoderms. Given their occurrence in the Cambrian, this group is often studied to understand the basic nature and origination of the metazoan body plan.

The study explores a new way to estimate ancient atmospheric CO₂ levels using chemical signals preserved in conodonts. It shows that differences in carbon isotopes between these fossils and surrounding rocks track major climate shifts during a key period as Earth moved from a warm to an icy climate

The authors use decay experiments with shrimp to show that arthropod setae do not exhibit signs of degradation, even after separation from the body. They suggest that fossil setae may be valid taxonomic indicators and that differences in setal numbers can be used to distinguish radiodont taxa.
