Examples
- The suborder Cephalaspida is an extinct group of armored fish-like vertebrates that lived during the Devonian and Carboniferous periods.
- The taxonomy of the suborder Cephalaspida is not clear, with some sources considering it a suborder of the class Osteostraci, while others place it in a separate class.
- Fossils of the suborder Cephalaspida have been found in Europe and North America, and are characterized by their distinctive head shields and armored bodies.
- The suborder Cephalaspida is thought to have evolved from a common ancestor with the class Osteostraci, but the exact relationships between the two groups are still unclear.
- Some researchers consider the suborder Cephalaspida to be a paraphyletic group, meaning that it does not contain all the descendants of a common ancestor, and therefore may not be a valid taxonomic classification.
