...Joseph H. Collette; James W. Hagadorn Abstract A phylogenetic analysis and review of Paleozoic phyllocarid systematics is presented using morphology-based characters from Cambrian to modern taxa. The resulting cladograms of the Phyllocarida suggest that the suborder Ceratiocaridina as traditionally...

... T he phyllocarida Packard, 1979, were a diverse and important group of arthropods during the Devonian Period. Although only locally abundant, phyllocarids were a significant macroarthropod group during the Middle and Late Devonian, comprising an important predatory component of marine ecosystems...

... of the eurypterid-dominated fauna is the unusual phyllocarid Gonatocaris decora (Clarke, 1901 ), originally described from a very limited number of specimens, none complete. This has hampered our understanding of the form and its place within the Phyllocarida (Collette and Hagadorn, 2010 ). The collections...

Traces attributed to phyllocarids include: Unnamed trace fossils interpreted to have been fodichnial burrows made by ceratiocaridid phyllocarids from the Silurian Eramosa Formation...

... species of Palaeopemphix Gemmellaro, 1890 from the Permian of Italy were also initially described as decapods, but after reexamination by Feldmann et al. (2004) were reassigned to Phyllocarida. The specimen described here differs from species of Stenopus Latreille, 1819 , in exhibiting...
