Carbonate biomineralization normally occurs in three distinct types: controlled, induced and influenced, each with its peculiar characteristics. Building-reef species within the family Cirratulidae (Annelida, Polychaeta) constitute the first known example of “double-phased” biomineralization among marine invertebrates, as they combine controlled and influenced biomineralization types in the process

Response of late Holocene vegetation to abrupt climatic events on the northwestern coast of the Bay of Bohai, China Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-28 Rongrong Wang, Yuecong Li, Shengrui Zhang, Qinghai Xu, Yawen Ge, Bing Li, Baoshuo Fan, Zhen Zhang, Cange Li, Ying Wang, Hanfei You, Yihang Cao, Yue Li
Coastal wetlands provide valuable ecosystem services and understanding their response to past climatic changes may help predict their possible future responses. In this paper, we obtained records of pollen, algae, sediment grain-size, and other environmental proxies, from a late Holocene sediment core (CFD-E) from the Caofeidian area, on the northwest coast of the Bay of Bohai, China. Our results indicate

Patch reefs with scleractinian corals and layered domical and bulbous growth forms (calcified sponges?) in the upper Maastrichtian and lowermost Palaeocene platform carbonates, Adriatic islands of Brač and Hvar (Croatia) Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-26 Maja Martinuš, Blanka Cvetko Tešović, Sonja Jurić, Igor Vlahović
New findings of numerous levels with scleractinian corals and layered domical and bulbous growth forms (calcified sponges?) within the upper Maastrichtian–lowermost Palaeocene shallow marine carbonates from the Adriatic islands Brač and Hvar (Croatia) are described. They indicate the existence of patch reefs developed on the Adriatic Carbonate Platform in the western Tethys area shortly before and

Coupling palaeobiology and geochemistry from the Holocene of the southern Adriatic Sea (Gulf of Manfredonia, Italy): Shelf facies patterns and eutrophication trends Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-26 Veronica Rossi, Irene Sammartino, Claudio Pellegrini, Giulia Barbieri, Chiara Teodoro, Fabio Trincardi, Alessandro Amorosi
The combined use of the meiofauna (benthic foraminifers and ostracods) and geochemical data from three cores, recovered in distinct bathymetric sectors of the southern Adriatic shelf (Apulia, SE Italy), provides new insights on the relationships between shallow-marine environments, sediment fluxes and eutrophication trends over the last ~7000 years. The stratigraphic distribution of meiofauna assemblages

Paleoenvironmental changes of Cuona Lake on the central Tibetan Plateau over the last 13 kyrs based on organic geochemical proxies Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-27 Ruifang Ma, Chuanfang Jin, Shichang Kang, Shijie Li, Wei Chen
The influence of the Indian summer monsoon (ISM) and mid-latitude westerlies on the central Tibetan Plateau (TP) during the Holocene, particularly during the mid-Holocene, is still unclear, limiting our understanding of past climate change in this region. Cuona Lake, located on the central TP, is a transitional zone of atmospheric circulation that is well situated for investigations on the interplay

Sediment provenance of the East Siberian Arctic Shelf and evidence of Holocene climate-driven fluvial events in the Indigirka River based on detrital mineral analysis Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-24 Kunshan Wang, Xuefa Shi, Jiang Dong, Aleksandr A. Bosin, Anatolii S. Astakhov, Zhengquan Yao
Analysis of sediment provenance in the East Siberian Arctic Shelf is crucial for the understanding of source to sink pathways and their link to climatic and environmental changes. In this paper, we conducted detrital mineral analysis on surface sediments and one sedimentary core (LV77–41-1) from the eastern Laptev Sea and the western shelves of the East Siberian Sea. Based on the results of light and

Biogeographic response to major extinction events: The case of Triassic bivalves Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-22 Javier Echevarría, Sonia Ros-Franch
Mass extinctions decimate the biota causing the disappearance of existing palaeobiogeographical patterns, which is not surprising given that palaeobiogeographical units are usually established on the basis of endemic taxa and these are the most affected in global crisis events. This paper deals with the evolution of the biogeographic pattern shown by bivalve genera in response to the end-Permian extinction

Can inter-annual climate variability alone explain the glacier retreat since the Little Ice Age in the Hailuogou catchment, southeastern Tibetan Plateau? Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-20 Yaqing Sun, Xiangke Xu, Hongjie Zhang, Jiule Li, Baiqing Xu
Inter-annual climate variability has the potential to induce hundred-to-thousand meters of glacier length change, comparable to the glacier retreats from their Little Ice Age (LIA) positions (Roe and O'Neal, 2009). Distinguishing the roles of inter-annual climate variability and climate change in glacier changes can help us read the true climate signal from the history of glacial activity and provide

The relationship of plant leaf δ13Cn-alkanes and salinity in coastal ecosystems applied to palaeobotany: Case study from the Cenomanian of the Bohemian Cretaceous Basin, Czechia Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-24 Petra Zahajská, Jana Čepičková, Jakub Trubač, Nikolai Pedentchouk, Jiří Kvaček
Stable carbon isotopes in fossil leaf cuticles (n-alkanes, δ13Cn−alkanes) extracted from the sediment are widely used for palaeoenvironmental reconstructions. This approach relies on a series of assumptions (such as the plant-group-specific isotopic range, or the atmospheric CO2 being the major factor for the isotopic values) and leaves out the complexity of the carbon isotope fractionation within

Timing of rifting of the Dongkaco microcontinent (Central Tibet) and implications for Neo-Tethyan evolution Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-24 Anlin Ma, Xiumian Hu, Xin Li, Alex Pullen, Eduardo Garzanti, Noritoshi Suzuki
Rifting of continental blocks away from northern Gondwana resulted in the development of several Tethyan oceanic branches, the number of which and the timing of tectonic processes are actively debated. Within the Mesozoic Bangong-Nujiang suture, locally exposed Paleozoic strata are potential witnesses of the early development of Tethyan basins, yet their origin and tectonic significance remain poorly

The Messinian salinity crisis onset in Albania: An integrated approach by bio-magnetostratigraphy and rock magnetic analyses Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-01-19 Diego Bigi, Stefano Lugli, Vinicio Manzi, Marco Roveri, Pandeli Pashko, Ibrahim Milushi, Giovanni Muttoni, Elena Turco, Anna Cipriani, Federico Lugli
We carried out an integrated stratigraphic study aiming the identification of the onset of the Messinian salinity crisis (MSC) in the Peri-Adriatic Depression, a region forming the northern front of the Albanides fold-and-thrust belt. The onset was identified in the Kavaje area within an interval of euxinic shales representing a time-equivalent deposit of the Primary Lower Gypsum of stage 1 of the
