Osteology Supports a Stem-Galliform Affinity for the Giant Extinct Flightless Bird Sylviornis neocaledoniae (Sylviornithidae, Galloanseres)
Fig 12
PCA plot showing separation of S. neocaledoniae from various megapodes and Gallus gallus.
The plot is based on leg bone measurements standardised for size using femur length and selected ratios of some lengths divided by tarsometatarsus length of various galliforms compared to (see S1 File).
