Phytoliths, pollen, and spores in a stratigraphic sequence from the Shishan Wetland (Azraq Basin, Jordan) and supported by modern pollen and phytolith data provide information on vegetation, climatic trends, and the influence of fire through MIS 2 and MIS 1. Additionally, a pilot study introduces an innovative approach that uses shape and morphometric parameters of Bulliform phytoliths to assess hydro-climatic changes. The phytolith terrestrial–aquatic ratio, grass–pollen size, and the Artemisia–Amaranthaceae ratio (A:C) indicate that during the Last Glacial Maximum (LGM), the study area was a wetland surrounded by steppe, and that during the deglaciation period (c. 20–11 ka), the wetland vegetation remained almost unchanged but the surrounding area tended to aridity. The phytoliths’ terrestrial ratio, the presence of C₄ grass phytoliths, and the low A:C is characterized by a reduced wetland and the establishment of a hot desert, like the present. The record at Shishan Marsh shows effective moisture trends concurrent with other records in the western southern Levant, but climatic events (Heinrich Stadial 1 and Younger Dryas) are not recorded because of the low time-resolution of the studied sequence. This study shows that combining pollen and phytoliths strengthens vegetation reconstruction by discerning local from regional floristic components and that Bulliform phytoliths are a potential tool to reconstruct hydro-climatic conditions.

El Juyo is a Cantabrian Lower Magdalenian cave site located approximately 8 km west of the city of Santander. The excavations covered an area over 40 m², and the stratified deposits reach 3.5 m thick, with an estimated duration of Magdalenian occupation of around 1,000 years. Here, we present the first study of the herpetofaunal assemblages from El Juyo and explore their significance in terms of quantitative palaeoclimatic and palaeoenvironmental reconstructions using different quantitative methods. The palaeoherpetofaunal assemblages documented at El Juyo have a much lower diversity than present day. All methods applied to these assemblages characterised the climate as colder (between −8.5 and −3.7°C) and dryer (between −415 and −344 mm) than today, whereas landscape reconstructions suggest humid open area together with a potentially good representation of woodland areas in the vicinity of the site. This indicates that the climate during the Dryas I was much colder and dryer than today, even if the proximity of the sea may have mitigated in some way the harshness of the climate in this area. Rainfall seasonality pattern changed between the coldest periods of the Dryas I and today from more abundant precipitation during summer to late fall and winter maximum.

The recent re-discovery in Dresden, Germany, of a well-provenanced sculpted marble skull by Baroque artist Gian Lorenzo Bernini (1598-1680) allowed the first forensic anthropological examination of a work of this kind, comparable to those performed on biological skulls. The natural details conveyed included an overall natural and unstylized appearance, hollowed interior vault space, detailed anatomical structures, natural morphological variability and asymmetry, dental pathology, and postmortem changes common to real skulls. Morphological traits useful for ancestry estimation also were depicted in sufficient detail to allow standard scoring methods. Metrical and morphological analysis indicated that the skull was most consistent with an adult male individual of European ancestry, although up-scaling in overall size was estimated at around 10%. The authors conclude that Bernini used a biological skull as a model in order to achieve this level of anatomical detail, in contrast with many other skeletal depictions in Renaissance and Baroque sculpture.

The taphonomic effects of avian taxa upon forensic scenes has been little researched, and shore species including gulls (Laridae) have received even less attention, despite their well-known behavior as scavengers of human food waste. In order to begin assessing their potential impact, a pilot study was undertaken on Appledore Island, Maine, USA, at the Shoals Marine Laboratory. This location was chosen for its isolation from most other vertebrate scavengers and its large, seasonal breeding colonies of gulls, primarily great black-backed (Larus marinus) and herring (L. argentatus) gulls. Two locations with fresh bones were monitored for scavenging activity, using trail cameras and Tile Mate® tracking chips. In addition, portions of the breeding colonies nesting areas along the rocky coast were surveyed for bones that must have derived at some distance from human-generated trash sources. All (n = 16) fresh bones underwent dispersal by gulls, with an average distance of 10 m and a maximum distance (in one case) of 85 m. Multiple bones from trash sources were transported a minimum of 150 m if locally acquired and a minimum of 10 km if acquired from the mainland. These bones had a maximum length of 192 mm and mass of 46.0 g. Gulls, with their global distribution, have the potential to be significant dispersers of human skeletal remains and should undergo additional taphonomic research.

Excavations from 2013 to 2015 at the site of Shishan Marsh 1 (SM1) in the Azraq Basin of eastern Jordan have yielded substantial late middle Pleistocene lithic assemblages in association with faunal remains. Faunal preservation is poor, but multiple taxa have been identified, including cf.Panthera leo,Gazellasp.,Boscf.primigenius,Camelussp.,Equusspp., cf.Stephanorhinus hemitoechus,Palaeoloxodoncf.recki, andElephascf.hysudricus. The overall Azraq habitat may have been most similar to a savanna ecosystem, with a mixture of open grassland/shrub habitats and more closed vegetation along the wetlands margins. These taxa were drawn to the relatively lush oasis environment, where they were a dietary resource of the hominin groups exploiting the wetlands resources.

Human skeletal remains in outdoor forensic sites often are dispersed from their point of initial deposition, making locating isolated bones difficult. Forested areas in particular may obscure remains, as bones stained from soft-tissue and leaf-litter decomposition may blend in with the forest floor or be hidden by understory. Wide skeletal dispersal presents other problems for searchers, including the difficulty in keeping track of which areas have been searched and maintaining proper spacing of searchers to prevent gapping. Little is known about success rates when searching for dispersed skeletal elements and the effects of searcher spacing, searching the same area twice, type of skeletal element, and understory growth. In order to test recovery rates searching through forested areas, isolated postcranial elements of white-tailed deer (Odocoileus virginianus) and crania of pigs (Sus scrofa) were laid out randomly in a large grid system and searched for. Overall recovery rates for n = 500 elements were 84.0% on the first pass-through and a cumulative total of 90.0% after the second pass-through, with 10.0% missed after both. Significant differences in recovery rates based upon bone type were noted, but no significant difference was found based upon searcher spacing (1 m vs. 2 m) or understory density (low vs. medium). Forensic archaeologists should note that even with careful searching under controlled conditions, exposed surface skeletal elements can be missed, a concern that is likely amplified under real field search conditions. To maximize remains detection, forensic search protocols should include narrow searcher spacing and double passes through search areas wherever possible.

Criminal dismemberment is accomplished using a variety of tools and frequently used to dispose or facilitate the transport of human remains in an attempt to hinder forensic investigation. The present research examined features that may differentiate cuts made in bone by various commercially available reciprocating saw blades. The partial limbs of adult white‐tailed deer (Odocoileus virginianus) were used as a proxy for human remains and were cut using five reciprocating saw blades and a hand‐powered hacksaw. The resulting false start and complete kerfs were examined macroscopically and microscopically. Kerf characteristics in which significant differences (p ≤ 0.05) between reciprocating blades were noted including minimum kerf width, kerf false start shape, presence of cut surface drift and harmonics, exit chipping size, and striation regularity. Interblade differences generally reflect class characteristics previously established for hand‐powered blades. The present research may aid in the identification of reciprocating saw use in forensic contexts.

Cranial remains retained from fallen enemies are commonly referred to as “trophy skulls,” and many such crania were acquired as souvenirs by U.S. servicemembers during WWII and the Vietnam conflict. These remains increasingly have become the subject of forensic anthropological analysis as their possessors, typically veterans or their relatives, try to discard or repatriate them. The present research uses a qualitative analytical approach to review 24 cases of reported trophy skulls (14 previously unpublished cases and 10 from the literature) to determine which perimortem and postmortem characteristics are most useful for generating a taphonomic profile. Overall, the taphonomic signature of trophy remains includes traits relating to acquisition and preparation, ornamental display, and subsequent curation. Contextual evidence and the biological profile also are considered when determining the possible origin of human cranial remains as a trophy skull. Thorough taphonomic analysis will aid in identifying these types of remains as trophy skulls.
