description Elvinia Overview
Elvinia is a genus of Late Cambrian trilobites known from North America. It belongs to the family Elvinidae and provides the name for the Elvinia Biozone, a biostratigraphic interval used to correlate upper Cambrian rocks. Because the genus is tied to a defined fossil zone, Elvinia is of interest to paleontologists studying the relative age of sedimentary layers, the distribution of Late Cambrian marine faunas, and changes in trilobite communities.
help Elvinia FAQ
What is Elvinia?
Elvinia is a genus of Late Cambrian trilobites known from North America. It belongs to the family Elvinidae and is important in identifying a particular interval of Cambrian rocks.
What is the Elvinia Biozone?
The Elvinia Biozone is a biostratigraphic interval named for the presence of Elvinia and related fossils. Geologists use such fossil zones to correlate rock layers that may be far apart.
When did Elvinia live?
Elvinia lived during the Late Cambrian. Its geological value comes from its association with a defined part of the upper Cambrian fossil record.
Why is Elvinia important to geologists?
Elvinia is more than a fossil genus because its occurrence helps define a named biozone. That makes it useful for comparing the relative ages of sedimentary rocks.
