Great appendage arthropods, phylogeny, Herefordshire Lagerstätte, Silurian
The mid-Silurian Wenlock Series Herefordshire Lagerstätte preserves invertebrates in three-dimensions as calcitic void in-fills in carbonate nodules within a volcaniclastic horizon. A new arthropod from this fauna belongs to the ‘short great appendage’ (megacheiran) group. Phylogenetic analysis, based on the most detailed panarthropod character matrix yet assembled, recovers the new Herefordshire genus with other short great appendage genera in a clade that is the most derived of the euarthropod stem. It thus provides new insights into the nature of this stem and the morphology of immediately pre-crown group forms; its phylogenetic position, as well as that of other short great appendage genera, contrasts with the position of this group as determined in many other studies, in which they have been considered to be part of the chelicerate stem lineage; and the new genus represents the first identification of a short great appendage form in strata younger than mid-Cambrian in age..
