Following the Cambrian Explosion and the appearance in the fossil record of most animal
phyla associated with a range of new body plans, the Ordovician and Silurian periods …

This paper proposes a global review of Hirnantian event stratigraphy. The Hirnantian GSSP
in south China is tentatively correlated with latest Ordovician strata from the peri …

Many negative δ 13C excursions in marine carbonates from the geological record are
interpreted to record significant biogeochemical events in early Earth history. The …

Abstract The Yangtze Sea of the South China Craton experienced strong environmental
perturbations during the first~ 5-6 Myr of the Silurian. The Lower Silurian Lungmachi …

Marine cycles driven by astronomical orbital periods, may reflect sea-level fluctuations,
which considerably influence organic matter (OM) accumulation, redox conditions, and …

Graptoloid evolutionary dynamics show a marked contrast from the Ordovician to the
Silurian. Subdued extinction and origination rates during the Ordovician give way, during the …

Glacial episodes have been linked to Ordovician–Silurian extinction events, but cooling itself
may not be solely responsible for these extinctions. Teratological (malformed) assemblages …

Abstract The Silurian-Devonian interval is an essential period in Earth history for witnessing
the rise of sarcopterygian fishes and terrestrial vascular plants. In addition to its implication …

Biogenic carbonate minerals are widely used as archives in paleoenvironmental research,
providing substantial information for past depositional and diagenetic regimes. However …

The resolution and fidelity of global chronostratigraphic correlation are direct functions of the
time period under consideration. By virtue of deep-ocean cores and astrochronology, the …
