description Harpides Overview
Harpides is an extinct genus of harpetid trilobites recorded from Cambrian and Ordovician marine rocks. It is distinguished by a broad cephalic fringe extending around the head shield, with a pitted surface that recalls the better-known genus Harpes. The genus is relevant to studies of harpetid diversity and the evolution of specialized trilobite head structures in early Palaeozoic seas.
help Harpides FAQ
What is Harpides?
Harpides is an extinct genus of harpetid trilobites recorded from Cambrian and Ordovician marine rocks. It is known from fossils rather than from any living species.
What feature distinguishes Harpides from many other trilobites?
Its head shield has a broad cephalic fringe extending around the margin. The fringe has a pitted surface that recalls the better-known harpetid genus Harpes.
When did Harpides live?
Fossil records place the genus in the Cambrian and Ordovician periods of the Paleozoic Era. Those rocks preserve marine environments in which trilobites lived on or near the seafloor.
What was a trilobite's cephalic fringe used for?
The exact function is not certain, but the broad fringe may have helped with feeding, sediment interaction, or stabilizing the animal on the seafloor. In Harpides, its pitted surface is an important feature for identification.
