Ellipsocephalus is a genus of ptychopariid trilobites from the Cambrian Period. It is especially associated with Cambrian rocks of Bohemia in the Czech Republic, where the species Ellipsocephalus hoffi is a well-known fossil. The genus has a generally smooth exoskeleton and a broad, clearly segmented body typical of many early Cambrian trilobites. It is used in research and teaching concerning Cambrian marine ecosystems and trilobite evolution.
help Ellipsocephalus FAQ
When did Ellipsocephalus live, and what kind of fossil is it?
Ellipsocephalus is a trilobite genus from the Cambrian Period, representing an extinct marine arthropod. It belongs to the ptychopariid group, which includes many classic Cambrian trilobites.
Why is Ellipsocephalus hoffi associated with Bohemia?
Ellipsocephalus hoffi is a well-known species from Cambrian rocks in Bohemia, now part of the Czech Republic. That regional connection makes it an important name in studies of the Bohemian trilobite record.
What did the Ellipsocephalus exoskeleton look like?
Ellipsocephalus is generally described as having a relatively smooth exoskeleton rather than heavy spines or dense tubercles. Its smooth surface is one useful visual clue when comparing it with more ornamented Cambrian trilobites.
Where are Ellipsocephalus fossils especially associated with?
The strongest geographic association is with Cambrian rocks in Bohemia, in the Czech Republic. A specimen labeled Ellipsocephalus should therefore be checked against its locality and Cambrian age rather than identified from appearance alone.
