Figure 2 in Comparative osteology and phylogenetic relationships of Miocaperea pulchra, the first fossil pygmy right whale genus and species (Cetacea, Mysticeti, Neobalaenidae)
Figure 2. Miocaperea pulchra gen. et sp. nov.: holotype. A, dorsal view; B, ventral view; C, right lateral view; D, left lateral view. In (A) the anterior portion (rostrum) is on the same plane as that on which the neurocranium is lodged, in order to better show the nasal bones. This results in wide gaps between the maxillae and the supraorbital processes of the frontal. Such gaps are absent in (B) because the anterior portion is closer to the neurocranium, to represent the whole skull in articulation.

Figure 18 in Comparative osteology and phylogenetic relationships of Miocaperea pulchra, the first fossil pygmy right whale genus and species (Cetacea, Mysticeti, Neobalaenidae)
Figure 18. Phylogenetic relationships of baleen-bearing mysticetes resulting from the tree bisection and reconnection search and plotted against stratigraphic ages of the included taxa. Thick lines represent documented records; thin lines represent inferred ghost lineages. Ma, million years. The grey area represents a period of high origination rate in mysticete evolution. The divergence of Balaenidae and Neobalaenidae is calibrated on the stratigraphic age of Morenocetus parvus, the earliest described balaenid (the assignment to Balaenidae was confirmed by Bisconti, 2005).

Comparative Analysis of Complete Chloroplast Genomes of 13 Species in Epilobium, Circaea, and Chamaenerion and Insights into Phylogenetic Relationships of Onagraceae
<p>This is all the alignments which used to constructed a phylogenetic tree in our study about Onagraceae. The evening primrose family, Onagraceae, is a well defined family of the order Myrtales, which comprises 22 genera widely distributed from boreal to tropical areas. In the present study, we report and characterize the complete chloroplast genome sequences of 13 species in <em>Circaea</em>,<em> Chamaenerion</em>, and <em>Epilobium</em> using a next-generation sequencing method. We also retrieved plastome sequences from two other Onagraceae genera to characterize the chloroplast genome of the family. The complete plastomes of Onagraceae showed a typical quadripartite structure and encoded an identical set of 112 genes (with exclusion of duplication), including 78 protein-coding genes, 30 transfer RNAs, and four ribosomal RNAs. The results show that chloroplast genomes are basically conserved in gene arrangement across the family. Whereas, a large segment of inversion was detected in the LSC region of all samples in the<em> Oenothera </em>subsect. <em>Oenothera</em>. An inverted repeat (IR) contraction was found in <em>Circaea</em> and<em> Ludwigia </em>samples. We also compared chloroplast genomes across the Onagraceae samples and revealed similarities in some features, including nucleotide content, codon usage, RNA editing sites, and simple sequence repeats (SSRs). Phylogeny was inferred by the chloroplast genome data using maximum-likelihood (ML) and Bayesian inference (BI) methods. The generic relationship of Onagraceae was well resolved by the complete plastome sequences, showing potential value in inferring phylogeny within the family. <em>Oenothera </em>phylogeny was better resolved than other densely sampled genera. Biparental transmission may be the main cause of higher variation in the genus<em> Oenothera</em>.</p>
