Fig. 6. Ornithischian dinosaur Stenopelix valdensis Meyer, 1857, holotype (GZG 741/2, formerly GPI Gö 741−2), from the Obernkirchen Sandstone (Early Cretaceous: Berriasian), near Bückeburg, Niedersachsen, Germany.

Fig. 1. Ornithischian dinosaur Stenopelix valdensis Meyer, 1857, holotype (GZG 741/2, formerly GPI Gö 741−2), from the Obernkirchen Sandstone (Early Cretaceous: Berriasian), near Bückeburg, Niedersachsen, Germany.

Fig. 7 in New skeleton from the early Oligocene of Germany indicates a stem-group position of diomedeoidid birds

Fig. 7. Relationships between crown group Procellariiformes and the Diomedeoididae. The two nodes are characterized by the characters: 1, cotyla scapularis of coracoid shallow; 2, mandibular symphysis short; processus supracondylaris dorsalis large; legs short (note that the Hydrobatinae are intermediate in the last two characters mentioned).

Fig. 1 in Molecular Determination of the Phylogenetic Position of a Species in the Genus Colpodella (Alveolata)

Fig. 1. Consenses of optimal trees found from parsimony analysis of SSU rDNA aligned with MALIGN using all aligned sites (A), only conservative sites (B), and excluding outgroup taxa for all sites (C) and conservative sites only (D). Branches are drawn proportional to amount of change. Values at internodes for groups of interest are parsimony jackknife support indices (asterisk indicates not supported with this method). Thickened branches indicate implied retention of the Colpodella/Perkinsus morphology.

Fig. 2 in Molecular Determination of the Phylogenetic Position of a Species in the Genus Colpodella (Alveolata)

Fig. 2. Consenses of optimal trees found from parsimony analysis of combined 18S rDNA and actin nucleotide sequences (SSU rDNA data were only available for 24 taxa) for all available sites (A) and for conservative SSU rDNA sites (B); values at internodes are Bremer support indices. Optimal tree (C) found for combined analyses using only those taxa for which both genes are available; values at internodes are Bremer support indices for the 18S rDNA data (above nodes) and for the actin data (below nodes). Thickened branches indicate implied retention of the Colpodella/Perkinsus morphology.
