FIGURE 10. Bats. 1 in Late Holocene land vertebrate fauna from Cueva de los Nesofontes, Western Cuba: Stratigraphy, chronology, diversity, and paleoecology
FIGURE 10. Bats. 1, left hemimandible of Artibeus anthonyi (no, 1663, lower Level III). 2, ventral view of Phyllops vetus incomplete skull (no. 37, Level II). Both specimens were radiocarbon-dated (14C). 3, four hemimandibles of Antrozous koopmani (no. 20, 75, 1429, 1430 from Levels II and IV, also 14C dated). These specimens were also dated, helping corroborate the chronology discussed. The scale bar equals 10 mm.

Fig. 2 in The first report of South American edrioasteroids and the paleoecology and ontogeny of rhenopyrgid echinoderms
Fig. 2. Trees showing the phylogenetic position of rhenopyrgids with respect to other edrioasteroid clades. A. Strict consensus of the two, equally most parsimonious trees of 18 evolutionary steps. Numbers at nodes are the bootstrap and decay index for these nodes. B. Single most parsimonious tree of 26 steps recovered when the search was constrained to retain only those trees that placed Rhenopyrgus Dehm, 1961 as sister taxon to the pyrgocystid Argodiscus Prokop, 1965. Note that except for the placement of Rhenopyrgus, the trees are congruent.
