FIGURE 5 in Behavioural impacts on the taphonomy of dragonflies and damselflies (Odonata) from the Lower Cretaceous Crato Formation, Brazil
FIGURE 5. Pie charts showing abdominal completeness of Crato Formation Odonate versus other insect orders. A, Pie chart showing the number and percentage of odonate insect fossils examined with varying levels of abdomen preservation. The percentage is of odonates only, not the entire collection examined.

FIGURE 4 in Behavioural impacts on the taphonomy of dragonflies and damselflies (Odonata) from the Lower Cretaceous Crato Formation, Brazil
FIGURE 4. Principal coordinate analyses of the collection studies. Odonate specimens are connected with a red overlay. Nonodonate specimens are connected with a blue overlay. A, Including both anterior and posterior abdomen characters. B, With the anterior and posterior abdomen characters combined into a single abdomen character. C, Including both anterior and posterior abdomen characters, however three odonate and six non-odonate outliers are excluded in the overlain colours. D, With the anterior and posterior abdomen characters combined into a single abdomen character however two odonate and six non-odonate outliers are excluded in the overlain colours. All analyses use Gower similarity coefficient. Red = Odonata; blue = Blattodea; green = Orthoptera; light blue = Coleoptera; purple = Diptera; light green = Ephemeroptera; black = Hemiptera; yellow = Hymenoptera; orange = Neuroptera; pink = Raphidioptera; grey = Unknown.
