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.

Data from: Re-evaluating the geological evidence for Late Holocene marine incursion events along the Guerrero Seismic Gap on the Pacific Coast of Mexico
Despite the large number of tsunamis that impact Mexico's Pacific coast, stratigraphic studies focusing on geological impacts are scanty, making it difficult to assess the long-term risks for this vulnerable region. Surface samples and six cores were taken from Laguna Mitla near Acapulco to examine sedimentological and geochemical evidence for marine incursion events. Sediment cores collected from behind the beach barrier are dominated by intercalated layers of peat and inorganic sediments, mostly silt and clay, with little or no sand. Sand- and shell-rich clastic layers with high levels of sulfur, calcium, and strontium only occur adjacent to the relict beach ridge remnants near the center of the lagoon. With the exception of one thin fine sand layer, the absence of sand in the near-shore cores and the predominance of the terrigenous element titanium in the inorganic layers, evidently eroded from the surrounding hillslopes, suggests that these large-grained intervals do not represent episodic marine incursions, but rather were likely formed by the erosion and redeposition of older marine deposits derived from the beach ridge remnants when water levels were high. These results do not support the occurrence of a large tsunami event at Laguna Mitla during the Late Holocene.
