Setting the stage: Building and maintaining a habitable world and the early conditions that could favor life's beginnings on Earth and beyond Open
The Hadean, once thought to be uninhabitable and tumultuous, has more recently been recontextualized as a clement time in which oceans, land, and life likely appeared on Earth. This non-exhaustive chapter follows multiple threads from plan…

Dynamic evolution of marine productivity, redox, and biogeochemical cycling track local and global controls on Cryogenian sea-level change Open
The Cryogenian period of the Neoproterozoic was marked by two Snowball Earth glaciations that bookended a non-glacial interval that lasted roughly 10 million years. The break-up of Rodinia in the early Neoproterozoic gave rise to numerous …

Giving Some Tooth to Precambrian Carbonates and the Tales They Tell About Ancient Oceans Open
Enigmatic is a word that often comes up in discussions about Proterozoic molar tooth carbonate structures (MTS). But when unusual features such as these are common in rocks of a particular age, there is almost always an important message w…

Environmental drivers of the first major animal extinction across the Ediacaran White Sea-Nama transition Open
The Ediacara Biota—the oldest communities of complex, macroscopic fossils—consists of three temporally distinct assemblages: the Avalon (ca. 575–560 Ma), White Sea (ca. 560–550 Ma), and Nama (ca. 550–539 Ma). Generic diversity varies among…

Impact of post-depositional transformation on sedimentary rocks and implications for paleoenvironmental studies: Evidence from  Mesoproterozoic (1.1 Ga) sediments from the Taoudeni basin, Mauritania Open
<p>Understanding and reconstruction of the paleo-condition dynamics linked to biological evolution in Earth history remain a big challenge because a majority of the ancient rocks have been affected by secondary modification processes…

Permian–Triassic evolution of the Bivalvia: Extinction-recovery patterns linked to ecologic and taxonomic selectivity Open
The Bivalvia is an important benthic clade that was relatively less affected than other benthos during the Permian–Triassic (P–Tr) biotic crisis, reporting losses of 85%, 64%, and 32% at the species, genus and family levels, respectively. …
