PERMANOVA results testing the difference between the centroids of the composition of samples for the members of the Werfen Formation.

A) Main Test. P(Perm) = permutational p-value. P(MC) = Monte Carlo p-value. B) Pair-wise comparisons. Comparisons between the different members based on taxonomic composition are shown in bold and functional composition is shown in italics. The Tesero and San Lucano members were excluded from the tests as they have <3 samples. GOM = Gastropod Oolite Member.
