Mercury spikes suggest volcanic driver of the Ordovician-Silurian mass extinction

Scientific Reports, 2017
The second largest Phanerozoic mass extinction occurred at the Ordovician-Silurian (O-S) boundary. However, unlike the other major mass extinction events, the driver for the O-S extinction remains uncertain.

Evolution of leaf-form in land plants linked to atmospheric CO2 decline in the Late Palaeozoic era [PDF]

, 2001
The widespread appearance of megaphyll leaves, with their branched veins and planate form, did not occur until the close of the Devonian period at about 360 Myr ago.

The Silurian mesophotic coral ecosystems: 430 million years of photosymbiosis

Coral reefs, 2018
The Silurian Period witnessed one of the most profound intervals of reef development in the history of the Earth, formed in large part by tabulate and rugose corals and stromatoporoid assemblages.

Bahaman patch reefs: Numerous and neglected

The Depositional Record, EarlyView.
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?

Bryozoan–cnidarian mutualism triggered a new strategy for greater resource exploitation as early as the Late Silurian

Scientific Reports, 2022
Bryozoans were common benthic invertebrates in the Silurian seas. The large biodiversity among Silurian benthic organisms prompted diversified interactions, and as a result bryozoans hosted many other organisms as symbionts.
