a, Principal component analysis (PCA) of variables of climatic importance showing pterosaurs (n = 23), pre-Norian lagerpetids (n = 9) and Norian–Rhaetian lagerpetids (n = 17). b–e, Raincloud plots comparing climatic variables between pterosaur and lagerpetids: mean annual temperature (b); mean annual precipitation (c); seasonal variation in temperature (d); seasonal variation in precipitation (e). f, The time-sliced PCA space occupation of lagerpetids and pterosaurs through the Triassic. Results of statistical comparisons are reported in Extended Data Table 1. P, precipitation; T, temperature. The box plots display the median and interquartile range (IQR), the upper whiskers extends from the 75th percentile to the largest value and the lower whiskers extends from the 25th percentile to the lowest value.
