FIGURE 3 in Trilobite moulting behaviour variability had little association with body proportions

FIGURE 3. Principal Components Analysis plots with specimens grouped by mode of moulting (A) or generalised moult configuration (B) (see legends). Plot C shows the contributions of the dataset variables to the morphospace in A and B; directionality of each arrow represents how it varies across the morphospace, and length of each arrow represents its comparable impact on the morphospace. TT: thoracic tergite number, LT: thoracic axial length, WT: thoracic maximum width, CW: cranidial width, CL: cranidial axial length, CJW: cephalothoracic joint width.

CrW: cranidial width (tr.), CrL: cranidial axial length (sag.), CThW: cephalothoracic joint width (tr.), ThW: thoracic maximum width (tr.), ThL: thoracic axial length (sag.), PyW: pygidial maximum width (tr.), PyL: pygidial axial length (sag.), TBL: total axial body length (sag.).

FIGURE 6 in Trilobite moulting behaviour variability had little association with body proportions

FIGURE 6. Scatterplots of the total dataset, for each metric morphometry variable. Data is grouped by mode of moulting (see legend). Linear regression lines represent the MANCOVA analysis models (see text).

FIGURE 5 in Trilobite moulting behaviour variability had little association with body proportions

FIGURE 5. Box plots displaying mean (black square) and median (horizontal black line) average thoracic tergite number for each mode of moulting group (A) and generalised moult configuration (B). Grey jitter shows the plotted points comprising the boxes (jitter spread across the x-axis is purely for visualisation), and black points show suggested outliers.

FIGURE 7. Histograms of notable variables within the dataset (using only complete data entries), with plotted EM algorithm-calculated distributions. A: thoracic axial length histogram, with two estimated distributions. B: pygidial axial length histogram, with three estimated distributions; two (blue and green lines) are exactly overlapping, indicating they represent the same distribution. C: thoracic tergite number, with three estimated distributions. D: PCA plot, with specimens grouped by generalised moult configuration (see legend) and ellipses removed (original plot in Figure 3B); dashed black boxes roughly demonstrate the three major data clusters apparent in the morphospace.

Fig. 5 in Sequence of post-moult exoskeleton hardening preserved in a trilobite mass moult assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco

Fig. 5. Mid-moult specimen of Limulus polyphemus Linnaeus, 1758 (YPMIZ 55597), Recent, USA, in dorsal (A1), ventral (A2), and anterior (A3) views. The moult is fully hardened and shows a robust convex exoskeleton, whereas the carcass partially emerged but trapped within the old exoskeleton shows extensive lateral wrinkling of its new exoskeleton (arrowed).
