Fig. 3: Micro-CT characterisation of eggshell morphotypes.
From: Molecular exploration of fossil eggshell uncovers hidden lineage of giant extinct bird
a Bar chart comparing the mean porosity, mean ‘average volume per pore’ (proportional to pore area), and mean pore density within the ROI examined of each eggshell morphotype. Error bars represent 95% confidence intervals of the standard error. Significant differences (p < 0.013, two-sided Mann–Whitney U test with Bonferroni correction, Supplementary Table 11) are indicated by an asterisk. b Representative micro-CT scans of each eggshell morphotype showing the outer surface and internal pore structures. Source data for this figure can be found in Supplementary Data 8 and 12.
