New information on the holotype of “ Chasmosaurus ” russelli (Ornithischia: Ceratopsidae) necessitates the establishment of a new genus to receive the species

Dinosaur Provincial Park — 2026 — WHE3B05B4760F

A re-evaluation of the holotype of Chasmosaurus russelli from Dinosaur Provincial Park, Alberta, reveals it cannot be classified within the genus Chasmosaurus or any other known chasmosaurine taxon due to its unique premaxilla and frill epiossifications. Phylogenetic analysis suggests ambiguous relationships, with the specimen potentially representing a migrant from the southern Pentaceratops clade or an independent lineage exhibiting convergent evolution of Pentaceratops-like traits. Consequently, the authors establish a new genus, Cryptarcus, to accommodate this species, refuting recent hypotheses of an evolutionary trend from Cryptarcus russelli through Pentaceratops to Terminocavus.

New Prehistoric Discoveries on Fortifications in Sicily

Megalithic Temples of Malta — 2026 — WHED4E12BEDAE

Recent research sheds light on the significant role of Sicily as a source and transit point for essential prehistoric materials, including flint, obsidian, and greenstone, which were crucial for Neolithic communities in Malta. The study reveals that Sicily's Hyblaean Mountains provided vital flint resources, while obsidian from Lipari and Pantelleria, along with greenstone from Calabria and the Western Alps, were transported through Sicily to Malta. This migration pattern is linked to the emergence of the Maltese megalithic temples (3600-2500 BC), suggesting a cultural exchange facilitated by these material movements. The findings highlight Sicily's importance in Neolithic trade networks and its influence on the development of Malta's unique temple-building tradition.

New records of five polydesmidan millipedes (Diplopoda, Polydesmida) from the Ogasawara Islands, Japan, with notes on the postembryonic development of Prosopodesmus spp. (Haplodesmidae)

Nitrate Source Apportionment and Nitrogen Export Characteristics of Spring Water in a Dolomite Karst World Heritage Site: A Tracing Study Based on Nitrogen and Oxygen Isotopes

South China Karst — 2026 — WHE920F541DC3

Dissolved nitrogen leaching, not just surface processes, significantly drives the evolution of karst rocky desertification in the Shibing Dolomite Karst World Heritage Site. A year-long study using monthly monitoring, hydrochemistry, and nitrate dual isotopes (¹⁵N and ¹⁸O) revealed stark differences between core and buffer zone springs. The buffer zone exhibits high anthropogenic nitrate dominance (>62%) with seasonal peaks, rapid hydrological response, and limited denitrification, while the core area shows stable natural nitrate levels (5–7.4 mg/L) and potential local denitrification. Nitrogen export in the buffer zone surges 4.5 times during the rainy season, primarily as NO₃⁻ (93% of TN), whereas the core area has a higher total nitrogen export flux per unit area (3.34 vs. 0.4 g/m²/a) with a greater proportion of dissolved organic nitrogen (DON). These findings highlight the critical role of dissolved nitrogen in shaping karst landscapes, offering new insights for conservation and management strategies.

Nocturnal Mating Behavior in Tibetan Macaques: The Low‐Ranking Male's Path to Mating Success

Mount Huangshan — 2026 — WHEBC9F514712

Nocturnal mating behavior in Tibetan macaques offers low-ranking males equal mating success to high-ranking ones, challenging traditional dominance-based reproductive strategies. A four-year study (2021-2025) at Mount Huangshan, China, using solar-powered night-vision cameras, revealed that nocturnal mating follows a bimodal pattern and is more frequent, prolonged, and non-forceful in the absence of high-ranking individuals. Lunar illumination positively correlated with mating frequency, suggesting darkness as an adaptive tactic for subordinates to increase reproductive opportunities. This research expands understanding of behavioral flexibility in diurnal primates and provides new insights into human mating behavior.
