description Kjerulfia Overview
Kjerulfia is a genus of Early Cambrian trilobites known from lower Cambrian deposits in Norway and Sweden. It is associated with the olenellid trilobites, an early branch of trilobite diversity that appeared during the initial expansion of the group. Fossils assigned to Kjerulfia are useful for studying Scandinavian Cambrian marine environments and the early evolution and geographic distribution of trilobites.
help Kjerulfia FAQ
What is Kjerulfia?
Kjerulfia is a genus of Early Cambrian trilobites known from lower Cambrian deposits in Norway and Sweden. It is associated with olenellid trilobites, an early branch of trilobite evolution.
When did Kjerulfia live?
Kjerulfia lived during the Early Cambrian, near the initial expansion of trilobite diversity. It is therefore older than Late Cambrian genera such as Ptychaspis and Elvinia.
Which trilobite group includes Kjerulfia?
Kjerulfia is associated with the olenellid trilobites. Olenellids are commonly discussed as an early Cambrian group with distinctive cephalic and thoracic features.
Where are Kjerulfia fossils found?
Fossils assigned to Kjerulfia are known from lower Cambrian rocks in Norway and Sweden. These deposits preserve marine ecosystems from an early stage of trilobite history.
