Supplementary material for Roca-Neyra Equids: Late Miocene to Early Pleistocene Hipparion - Equus database for multivariate and statistical analysis for European fossil Equids
<p>We undertake a redescription of the equid sample from the early Pleistocene of Roca – Neyra, France. This locality has been recently calibrated at the Pliocene/Pleistocene boundary (2.6 ± 0.2 Ma) and therefore it is of interest for the first appearance of the genus <i>Equus </i>and last appearance of hipparionine horses. The Roca – Neyra equid sample, re – analyzed herein using morphological, morphometrical and statistical analyses, has revealed the co – occurrence of <i>Plesiohipparion</i> cf. ?<i>P.</i> <i>rocinantis</i> and <i>Equus</i> cf.<i> E. livenzovensis</i>. The analysis undertaken on several European, African and Asian <i>"Hipparion"</i> sensu lato species from late Miocene to early Pleistocene has revealed different remnant <i>Hipparion</i> lineages in the Plio – Pleistocene of Europe: <i>Plesiohipparion</i>, <i>Proboscidippaion</i> and likely <i>Cremohipparion</i>. The discovery of the first European monodactyl horse, <i>Equus</i> cf. <i>E.</i> <i>livenzovensis</i> in itself correlates Roca – Neyra with other 2.6 Ma European localities in Italy, Spain and in the Khapry area (Azov Sea region). The morphological description of the <i>Equus</i> cf. <i>E. livenzovensis</i> lower cheek teeth has highlighted intermediate features between the North American Pliocene species <i>Equus simplicidens</i> and early Pleistocene European <i>Equus stenonis.</i> Our study supports the hypothesis that <i>E. livenzovensis</i> is a plausible evolutionary predecessor for the <i>Equus stenonis</i> group. These observations underscore the importance of Roca – Neyra, as an important locality for the last European hipparions and the first <i>Equus</i> in the early Pleistocene of Europe.</p>
Data from: Amplicon pyrosequencing late Pleistocene permafrost: the removal of putative contaminant sequences and small-scale reproducibility
DNA sequencing of ancient permafrost samples can be used to reconstruct past plant, animal and bacterial communities. In this study, we assess the small-scale reproducibility of taxonomic composition obtained from sequencing four molecular markers (mitochondrial 12S ribosomal DNA (rDNA), prokaryote 16S rDNA, mitochondrial cox1 and chloroplast trnL intron) from two soil cores sampled 10 cm apart. In addition, sequenced control reactions were used to produce a contaminant library that was used to filter similar sequences from sample libraries. Contaminant filtering resulted in the removal of 1% of reads or 0.3% of operational taxonomic units. We found similar richness, overlap, abundance and taxonomic diversity from the 12S, 16S and trnL markers from each soil core. Jaccard dissimilarity across the two soil cores was highest for metazoan taxa detected by the 12S and cox1 markers. Taxonomic community distances were similar for each marker across the two soil cores when the chi-squared metric was used; however, the 12S and cox1 markers did not cluster well when the Goodall similarity metric was used. A comparison of plant macrofossil vs. read abundance corroborates previous work that suggests eastern Beringia was dominated by grasses and forbs during cold stages of the Pleistocene, a habitat that is restricted to isolated sites in the present-day Yukon.

Fig. 8 in Characterizing Late Pleistocene and Holocene Stone Artefact Assemblages from Puritjarra Rock Shelter: A Long Sequence from the Australian Desert
Fig. 8. Flakes and amorphous retouched implements from the Holocene levels of Puritjarra rock shelter. Artefacts 8–10 are retouched flakes. Remainder of artefacts are unmodified flakes. From unit 1c: N9/6-1, N11/ 14-7, M10/13-3, M11/10-5. From unit 1b: N11/8-5, N11/9-3, N11/10-3, N13/9-3. From unit 1a: QR9/2, M10/4-1. M11/10-5 is a chert flake with fine overhang-removal flaking along the platform edge. N13/9-3 is a chalcedony flake with a short length of retouch on one lateral edge (shown by bar) and with fine nibbling along distal margin. M10/4-1 is a retouched chalcedony flake exhibiting a prior platform.
