Silurian Reefs in the Field

Fieldwork is one of the most important aspects of Geology and involves much more than simply going to a site and collecting rocks and fossils. No matter how beautiful or scientifically unique a specimen is, it's value is limited without a variety of accompanying data that can be gathered only in the field. Geologists who work with sedimentary rocks and fossils follow several standard procedures in their fieldwork.

Silurian reefs and fossils can be found across the world, which makes fieldwork and field sites some of the most important aspects of geology.

For a geologist studying Silurian reefs, field sites can be categorized as either "reef outcrops" or "interreef outcrops."  Reef outcrops are sites where a reef bed has been fossilized. Studying fossils from these sites shows they were relatively high in biodiversity.

Fossils of organisms and communities that lived apart from Silurian reefs can be found in interreef outcrops.  While not as diverse as more concetrated reef outcrops, at least 89 species of animals with hard parts occur in the interreef beds. Most of these species are rare and smaller than 3 cm in size.
