Adults of the gregarious larval endoparasitoid Tachinaephagus zealandicus Ashmead (Hymenoptera: Encyrtidae) were collected from two species of carrion-inhabiting flies, Phormia regina Meigen (Diptera: Calliphoridae) and Hydrotaea aenescens Wiedemann (Muscidae), associated with the burnt remains of a domesticated pig, Sus scrofa L. (Artiodactyla: Suidae), during late summer in south central Pennsylvania. This represents the first reported occurrence of the wasp in the state and only the second in the mid-Atlantic region. Collection from P. regina is a new host record for T. zealandicus and also the first for this parasitoid being attracted to flies on burnt remains.

Introduction: In the forensic field, having accurate understanding of the macroscopic and microscopic alterations that occur in teeth when exposed to temperatures has remarkable significance. The preservation of delicate incinerated teeth is crucial in fire investigations that pertain to the temperature exposed, as well as the identification of victims. This preservation is necessary in order to conduct macroscopic and microscopic ultra-structural examinations, which provide valuable insights into the structural alterations that dental tissues undergo when exposed to low to high temperatures.

In case of severely burned bodies, victim identification by visual or fingerprints recognition is often prevented by altered body conditions. To overcome these circumstances, different techniques are available. Among these, the most reliable is molecular identification, especially in cases of detached body parts.

We present an interdisciplinary analysis of finds from the Trypillia settlement of Kosenivka, Ukraine (ca. 3700-3600 BCE, Trypillia C1-2), that links information on human, faunal, and botanical remains with archaeological data to provide exceptionally detailed insights into life and death at a giant Trypillia settlement. We obtained osteological, palaeopathological, morphological and histotaphonomic data from human bone fragments; performed carbon and nitrogen stable isotopic analysis of human and animal bone to calculate food webs; modelled newly generated radiocarbon dates to refine the site's chronology; and contextualised the finds within the phenomenon of a general lack of human remains in Early and Middle Trypillia times through a literature review.

The early radiation of dinosaurs remains a complex and poorly understood evolutionary event. Here we use hundreds of fossils with direct evidence of feeding to compare trophic dynamics across five vertebrate assemblages that record this event in the Triassic-Jurassic succession of the Polish Basin (central Europe). Bromalites, fossil digestive products, increase in size and diversity across the interval, indicating the emergence of larger dinosaur faunas with new feeding patterns.

Climate change has significantly impacted the wildfire regimes in lodgepole pine forests, resulting in prolonged fire seasons and altered fire behaviour. In North America, fire patterns have shifted towards more frequent and severe wildfires after a century of fire suppression. In response, silviculture practices in fire-prone areas should aim to restore diverse forest structures that are resistant or resilient to wildfires.
