Sexual dimorphism in a Late Ordovician caryocaridid (Malacostraca, Phyllocarida) identified by carapace geometric morphometrics

This dataset contains morphometric measurements of 95 caryocaridid
phyllocarid carapaces (Soomicaris ordosensis) from the Upper Ordovician
(Katian) Lashizhong Formation of North China. Parameters include height,
length, anterior-horn angle, projected area and perimeter obtained via
geometric morphometrics. Three carapace types (T1–T3) were distinguished
and are provided together with raw TIFF images of modern analogues,
stratigraphic columns and PCA results. The data support the accepted
article in Paleobiology and can be reused for evolutionary, biogeographic
or taxonomic studies of Paleozoic phyllocarids.
