Recent fossil discoveries from the lower Cambrian Emu Bay Shale (EBS) on Kangaroo
Island, South Australia, have provided critical insights into the tempo of the Cambrian …

The most successful chronostratigraphic correlation methods enlist multiple proxies such as
biostratigraphy and chemostratigraphy to constrain the timing of globally important bio-and …

The Emu Bay Shale (EBS) of South Australia is anomalous among Cambrian Lagerstätten
because it captures anatomical information that is rare in Burgess Shale–type fossils, and …

Exceptionally preserved fossils from the Palaeozoic era provide crucial insights into
arthropod evolution, with recent discoveries bringing phylogeny and character homology …

Ecdysis, the process of moulting an exoskeleton, is one of the key characters uniting
arthropods, nematodes and a number of smaller phyla into Ecdysozoa. The arthropod fossil …

The fossil record, including the record of Burgess Shale-type deposits, is biased towards late
ontogenetic stages. Larval stages, juvenile and subadult specimens exist but are very rare …

Estuarine deposits of the Furongian Pico de Halcón Member of Argentina contain trace and
body fossils that allow assessing the role of evolutionary and environmental factors on early …

Large collections of Eccentrotheca helenia sp. nov. from the lower Cambrian Wilkawillina
and Ajax limestones in the Arrowie Basin, South Australia, contain abundant low, cap …

A unique dinosaur assemblage from the Cretaceous beds of western Inner Mongolia
preserves geologic and paleontologic data that clearly delineate both the timing and …

Sexual reproduction represents a fundamental aspect of animal biology, but the diversity of
reproductive strategies among early Paleozoic metazoans remains obscure. Direct evidence …
