Existing redox classifications and the calibrations of elemental proxies to modern
environmental redox scales are in need of re-evaluation. Here, we review environmental …

Recent fossil discoveries from the lower Cambrian Emu Bay Shale (EBS) on Kangaroo

Abstract The Toarcian Oceanic Anoxic Event (T-OAE;~ 183 Ma) of the Early Jurassic period
is considered a second-order bioevent, of major importance in the Mesozoic. This event …

Burgess Shale-type fossil assemblages provide a unique record of animal life in the
immediate aftermath of the so-called “Cambrian explosion.” While most soft-bodied faunas …

To better understand temporal variations in species diversity and composition, ecological
attributes, and environmental influences for the Middle Cambrian Burgess Shale community …

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 …

Despite numerous attempts, classification of the Precambrian fossil Dickinsonia has eluded
scientific consensus. This is largely because Dickinsonia and its relatives are structurally …

The early Cambrian succession at Chengjiang contains the most diverse Cambrian fossil

The Middle Cambrian Spence Shale Member (Langston Formation) and Wheeler and
Marjum Formations of Utah are known to contain a diverse soft-bodied fauna, but important …

Mid-Cambrian biotas of the Spence, Wheeler, Marjum, and Weeks formations in Utah are
exceptionally diverse. Continued collecting has produced additional trilobites here assigned …
