Fig. 2: Lineage diversity and dental topographic disparity in Afro-Arabian primates and rodents from the early Eocene to the middle Miocene.
From: Widespread loss of mammalian lineage and dietary diversity in the early Oligocene of Afro-Arabia
The blue line is the LTT plot for the primate and rodent species for which M2 dental topographic metrics were calculated; the orange line shows temporal changes in the sum of the square roots of 2D hull areas for all four clades, with 2DHA calculated for each clade (Anomaluroidea, Anthropoidea, Hystricognathi, and Strepsirrhini) independently (sumSR2DHA); the green line shows temporal changes in the length of the minimum spanning tree (MST), calculated for each clade (Anomaluroidea, Anthropoidea, Hystricognathi, and Strepsirrhini) independently (sumMST). sumSR2DHA and sumMST show a tight correlation with lineage number, as shown by the r2 values in the insets (n = 80). Bart. = Bartonian, Aqui. = Aquitanian, Burd. = Burdigalian, Lan. = Langhian.
