description Pseudophillipsia Overview
Pseudophillipsia is a genus of phillipsiid trilobites from late Carboniferous and Permian marine rocks. Fossils attributed to the genus occur in parts of the former Tethys region, including areas of Asia. It belongs to one of the trilobite lineages that survived into the Permian, when trilobite diversity was already much lower than in earlier periods. The genus is therefore relevant to studies of late trilobite persistence and extinction.
help Pseudophillipsia FAQ
When did Pseudophillipsia live?
Pseudophillipsia occurs in late Carboniferous and Permian marine rocks. It belongs to the phillipsiid trilobites, one of the lineages that persisted later than many other trilobite groups.
Where are Pseudophillipsia fossils found?
Records attributed to Pseudophillipsia occur in parts of the former Tethys region, including areas of Asia. The Tethys was an ancient ocean, so the geographic label refers to reconstructed paleogeography rather than a modern coastline.
Why is Pseudophillipsia important in trilobite history?
Pseudophillipsia is notable because phillipsiids survived into the Permian, near the end of trilobite history. That makes the genus relevant to questions about how some trilobite lineages persisted while others disappeared earlier.
Was Pseudophillipsia a freshwater trilobite?
No, fossils attributed to Pseudophillipsia come from marine rocks. Like other trilobites, it had a mineralized exoskeleton divided into a cephalon, thorax, and pygidium.
