3D scatterplot of Orrak cranial measurements compared to other Micronesian male samples.

3D scatterplot of Orrak cranium D compared to western Pacific and oceanic male samples.

<p>Maximum cranial breadth, maximum length and basion-bregma height produce a good overall view of cranial size and show that Orrak D is large <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003015#pone.0003015-Pietrusewsky1" target="_blank">[Comparative data from 10]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003015#pone.0003015-Hanihara1" target="_blank">[23]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003015#pone.0003015-Howells1" target="_blank">[98]</a>.</p

Femoral dimensions (mm) of specimens from Chelechol ra Orrak and Omedokel Cave [1].

<p>Note: The supero-inferior head diameter for specimen B:OR-15:18-013 recorded in this table (35.2 mm) is the measure that Berger et al. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003015#pone.0003015-Berger1" target="_blank">[1]</a> report in the text (p. 5). However in their <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003015#pone-0003015-t001" target="_blank">Table 1</a> and supplementary data in Table 4, they report an Antero-posterior diameter of 36.1 mm which is used to calculate the mean. In the text, they report a biomechanical neck length for this specimen of 36.1 mm. It appears they have inadvertently transformed this neck length measure into an antero-posterior head diameter in their <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003015#pone-0003015-t001" target="_blank">Table 1</a> and supplementary data 4 Table and then used it in their calculations.</p
