Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Image data banks and geometric morphometrics

, 2010
This paper examines the opportunities offered by recent advances in digital image processing to allow access to natural history museum collections without direct handling of specimens. It specifically refers to two- and three-dimensional data recording and analysis in the frame of geometric morphometrics.

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.
