Human Long Bone Dataset for csg-toolkit
<p>The present dataset is provided for testing and demonstration purposes for the `csg-toolkit`, a GNU Octave package based on the "long-bone-diaphyseal-CSG-Toolkit". It consists of eight 3D triangular mesh bone models of bilateral bones <em>(humerus, ulna, femur, and tibia)</em> of the lower and upper limbs. These bones are part of the Athens modern reference skeletal collection and they have been digitized by means of 3D photogrammetry with an accuracy of 0.02mm. For reference, they belong to the same individual, a Greek male, 26 years old.</p>

Fig. 1 in Growth dynamics and body size evolution of South American long-necked chelid turtles: A bone histology approach
Fig. 1. Size distribution of chelid turtles represented in two different phylogenetic hypotheses from Maniel et al. (2018). Both topologies recover two alternative hypotheses (orange): the monophyly of the South American chelid clade (A) and the monophyly of the of the long necked chelid turtles (B) see Maniel et al. 2018, for more information). Grey, species smaller than 20 cm; green, 20–60 cm; blue and bold, larger than 60 cm. The size is based on the carapace length.
