Glacial depositions are widely discovered in the late Ediacaran strata all over the world, but
the temporal and spatial distributions of the Ediacaran glaciations remain poorly …

Sedimentary rocks contain a unique record of the evolution of the Earth system. Deciphering
this record requires a robust understanding of the identity, origin, composition, and post …

As signposted by the fossil record, the early Cambrian period chronicles the appearance
and evolutionary diversification of most animal phyla in a geologically rapid event …

The earliest geochemical indicators of microbes—and the enzymes that powered them—
extend back∼ 3.8 Ga on Earth. Paleobiologists often attempt to understand these indicators …

Cholesterol plays essential roles in animal development and disease progression. Here, we
characterize the evolutionary pattern of the canonical cholesterol biosynthesis pathway …

The Weng'an Biota is a fossil Konservat-Lagerstätte in South China that is c. 570–609 myr
old and provides an unparalleled snapshot of marine life during the interval in which …

Abstract Phosphorite of the Ediacaran Doushantuo Formation accumulated in the central
Guizhou province during the Neoproterozoic-Cambrian Phosphogenic Event, producing the …

The Neoproterozoic oxygenation event (NOE) is often considered to be synchronously and
possibly causally associated with the Cryogenian glaciations. Reconstructing early …

The embryo-like microfossils from the Ediacaran Weng'an Biota (ca. 609 million years old)
are among the oldest plausible claims of animals in the fossil record. Fossilization frequently …

Abstract Most of the Precambrian (> 538 Ma) fossil record, which includes the time before
the onset of macroscopic multicellular life, consists of minute organically preserved remains …
