description Peronopsis Overview
Peronopsis is a genus of small, blind agnostid trilobites from the Cambrian Period. It had an isopygous body plan, meaning the cephalon and pygidium were broadly similar in size, and its body was divided into a limited number of segments compared with many other trilobites. Peronopsis fossils are widely distributed and are used in biostratigraphy, the correlation and relative dating of sedimentary rock layers.
help Peronopsis FAQ
What kind of trilobite was Peronopsis?
Peronopsis was a small, blind agnostid trilobite from the Cambrian Period. Agnostids were marine arthropods with compact bodies and relatively few segments compared with many other trilobites.
What does isopygous mean in Peronopsis?
Isopygous means that the cephalon, or head shield, and pygidium, or rear shield, were broadly similar in size. This two-part appearance is a characteristic feature of many agnostid trilobites.
Could Peronopsis see?
Peronopsis is described as blind, so it lacked functional eyes. It would have lived in Cambrian marine environments and relied on other senses rather than vision.
When did Peronopsis live?
Peronopsis lived during the Cambrian Period. The description identifies it as a Cambrian agnostid but does not provide a narrower stage or exact age.
