FIG. 6 in First fossil records of the Recent Ovulid genus Pseudocypraea Schilder, 1927 (Mollusca, Gastropoda) with description of a new species

FIG. 5 in Temporal paralogy, cladograms, and the quality of the fossil record
FIG. 5. — Pectinate cladogram illustrating Pongidae relationships as currently understood; A, all nodes are temporally informative (orthologous). The age of diversification of Pan is more recent than the age of origin of (Homo, Pan); B, the addition of a fossil taxon (Homo neanderthalensis) defines a paralogous node and two new arrows of time (black arrows). Consequently the fit of ages of diversification of both Homo and Pan to stratigraphy is meaningless.
FIG. 4 in Temporal paralogy, cladograms, and the quality of the fossil record
FIG. 4. — Temporal paralogy and the origin of tetrapods. The possibility of osteolepiforms being ancestors of tetrapods has been reinterpreted based on a parsimony analysis (Ahlberg & Johanson 1998). Among osteolepiforms, the Tristichopteridae appear as the closest relative to the Tetrapoda. The common ancestor of both groups is represented by a paralogous node, and according to temporal hierarchy the relative inclusiveness of each of the sister-groups cannot be decided. As a consequence, the Tetrapoda can be supposed to have occurred before the first appearance of osteolepiforms (Eifelian). There are no arguments to see osteolepiforms as possible ancestors of tetrapods, if this question has any meaning when argued from a parsimony analysis.
FIG. 3 in Temporal paralogy, cladograms, and the quality of the fossil record
FIG. 3. — Temporal information and cladograms; A, maximally informative cladogram of taxa (A-F) and their ages (6-1). All nodes are orthologous, and the ages of the fossil specimens can be either consistent or not with the temporal hierarchy; B, the effect of a better knowledge of the fossil record by addition of the age of a supplementary taxon (N, 4) is the decrease in temporal resolution. The number of informative (orthologous) nodes decreases (white circles) as temporally ambiguous nodes appear (shown as grey circles) node leading to two terminals or a terminal and a paralogous node, the black circle corresponds a new paralogous node, indicating a temporal paralogy. The ages of sister-taxa (C, N) and (D, E, F) are temporal paralogs. Each arrow represents a semi-independent temporal hierarchy.
