Infaunal molting in Viaphacops orurensis (Bonarelli 1921) and its evolutionary implications

Section: Evolution and systematics, Presentation: Poster
Infaunal molting behavior, Paciphacops, Viaphacops, phylogenetics, Devonian, Argentina, Bolivia
New evidence of infaunal pattern in Viaphacops from Bolivia (Middle Devonian) now challenges a monophyletic relationship of Paciphacops from Argentina (Late Silurian-Early Devonian) as previously reported. This suggests that a revision of the phacopid group incorporating this behavioral character could help resolving systematic difficulties within the so-called Ananaspini tribe of Haas (1998). It will be the very first attempt to study phylogeny using behavioral characters in Trilobita..
