Just a small correction: it seems that the states in biome column are (0) rainforest,
(1) other and (2) mangrove, contrary to what is found in the caption now.

Figure 3: Area, tempo and mode of palm diversification. (a) Paleomap representing
the distribution of landmasses in the mid-Cretaceous period, dark grey upland land,
light grey lowland (100 million years (Ma), adapted from Beerling and Woodward ).
Laurasia, which is the most likely ancestral area reconstructed for the crown node
of palms, is highlighted. (b) Chronogram showing the three different biomes assigned
to each genus. Red: tropical rain forest; green: mangrove; blue: not tropical rain
forest; grey: ambiguous. Yellow circles indicate fossil calibration points. The vertical
black lines highlight the five subfamilies of palms with an illustration (drawings
by Marion Ruff Sheehan, L.H. Bailey Hortorium, Cornell University, except top one
(Arecoideae), which is reproduced with permission from Springer from Kahn and de Granville
. Yellow circles indicate calibration points used. Mo: oldest monocot fossil;
A: Sabalites carolinensis; B: Mauritiidites; C: Hyphaene kapelmanii; D: Attaleinae
fossil (see text for details). (c) Semilogarithmic mean lineage-through-time (LTT)
plot averaged over 1,000 posterior trees from the Bayesian analysis (left axis, triangles)
and percentage of missing taxa as a function of time (right axis, grey line). Short
dashed line = upper 95% confidence interval; long dashed line = lower 95% confidence
interval; filled square = extant number of palms species. Vertical black line indicates
threshold up to which the LTT plot is considered reliable even under incomplete taxon
sampling. Palm fossil indicates time of earliest known unequivocal fossil for the
family ( Sabalites fossil leaf image reproduced by permission of the Board of Trustees,
