Mesophotic vs. shallow water reefs: ecosystem connectivity in the Silurian of Gotland
The Lower Silurian Visby Beds (ca. 430 Ma) exposed on the island of Gotland (Sweden) yield the oldest so far described MCE’s (mesophotic coral...

Miniaturization during a Silurian environmental crisis generated the modern brittle star body plan
Pivotal anatomical innovations often seem to appear by chance when viewed through the lens of the fossil record. As a consequence, specific driving...

Teratological trilobites from the Silurian (Wenlock and Ludlow) of Australia
Documentation of malformed trilobites has presented invaluable insight into the palaeobiology of a wholly extinct euarthropod group. Although the...

Deducing photosymbiosis in extinct heliolitid corals
The matter of photosymbiosis in Paleozoic corals remains unresolved as it is not possible to directly check for the presence of algal symbionts in...

Low tropical diversity during the adaptive radiation of early land plants
The latitudinal biodiversity gradient, with tropical regions acting as ‘evolutionary cradles’, is a cornerstone of current biogeographical and...

The Silurian mesophotic coral ecosystems: 430 million years of photosymbiosis
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...

Sediment-Molting Relationship of Juvenile Limulus polyphemus (Arthropoda, Merostomata) and Predation Against them
Rustán et al. (Geology 39(5):495–8, 2011) hypothesized that some particular species of trilobites from the Upper Silurian of Argentina underwent...
