New conodont d18O records of Silurian climate change: Implications for environmental and biological events

Trotter, Julie; Williams, Ian; Barnes, Christopher; Männik, Peep; Simpson, Andrew

Description

A near-continuous, highly dynamic record of Silurian climate has been determined from conodont δ18O compositions (δ18Ophos), representing stratigraphic sections from four palaeocontinents. Following the late Ordovician–early Silurian glaciation, numerous small-scale climate cycles show an overall warming trend until the mid Llandovery (early-mid Telychian), then gradual cooling through the late Llandovery. Two major, multi-step cooling transitions of similar magnitude and duration (+2‰ within...[Show more]
