A 3D geometric morphometric dataset quantifying skeletal variation in birdsAlexander Bjarnason and Roger BensonKeywords: birds; geometric morphometrics; macroevolution; morphology; skeletondoi: 10.18563/journal.m3.125 Abstract Macroevolution is integral to understanding the patterns of the diversification of life. As the life sciences increasingly use big data approaches, large multivariate datasets are required to test fundamental macroevolutionary hypotheses. In vertebrate evolution, large datasets have been created to quantify morphological variation, largely focusing on particular areas of the skeleton. We provide a landmarking protocol to quantify morphological variation in skeletal elements across the head, trunk, hindlimb and forelimb using 3-dimensional landmarks and semilandmarks, and present a large pan-skeletal database of bird morphology for 149 taxa across avian phylogeny using CT scan data. This large collection of 3D models and geometric morphometric data is open access and can be used in the future for new research, teaching and outreach. The 3D models and CT scans of the 149 specimens related to this project can be downloaded at MorphoSource (https://www.morphosource.org/projects/00000C420) Menura novaehollandiae FMNH 336751 View specimen
