help Staurocephalus FAQ
What is a Staurocephalus trilobite known for?
Staurocephalus is an extinct genus of trilobite from the Ordovician period that is distinctly recognized for its cross-shaped glabella, which is the middle axis of the head shield. This unique anatomical feature makes it highly identifiable compared to other cheirurid trilobites.
Where have Staurocephalus fossils been discovered?
Fossils of Staurocephalus have been primarily recorded across multiple Ordovician stages in Baltoscandia and the British Isles. These ancient marine arthropods thrived in the shallow paleo-oceans covering what is now northern and eastern Europe.
What geological period did the Staurocephalus live in?
Staurocephalus lived during the Ordovician period, which occurred approximately 485 to 444 million years ago. They were part of the diverse marine ecosystems that existed long before the late Ordovician mass extinction event.
What family of trilobites does Staurocephalus belong to?
This specific trilobite belongs to the cheirurid family, which is an order of Phacopida. Members of this family, including Staurocephalus, typically possessed large eyes and prominent spines on their thorax and tail shields.
