Dinoflagellates are a major component of the modern plankton. Of the 2192 species of marine free-living dinoflagellates presently described, an increasing number are being shown to produce resting cysts (probably hypnozygotes) within their life cycle. With rare exception, only the resting cysts fossilize, so they are of central importance in tracing the history of dinoflagellates through geological time. Cysts of many of the more common dinoflagellate species have distinctive morphologies allowing their geographic and stratigraphic occurrences to be traced. An ever-increasing number of taxa are also being shown to produce distinctive cysts, potentially increasing our knowledge of the diverse representation of dinoflagellates through time. Here the organic-walled cysts of 73 rare, poorly known or morphologically problematic marine dinoflagellate cyst species belonging to the orders Gymnodiniales (nine species) and Peridiniales (64 species) are reviewed, described and illustrated, and their stratigraphic ranges assessed. The names Echinidinium aculeatum and Echinidinium transparantum are validated herein. Highlights ► 73 rare and endemic marine dinoflagellate cyst species are reviewed, described and illustrated. ► 9 belong to Gymnodiniales and 64 to Peridiniales. ► Echinidinium aculeatum and Echinidinium transparantum are validated.

“…The magnetic grain size proxy (Figure h) varies approximately concomitantly with centennial cooling events recorded by TOM from HML (Wang et al, ), stalagmite δ 18 O from Dongge Cave (Dykoski et al, ), southern China precipitation (Hu et al, ), and North Atlantic ice‐rafted hematite stained grains (Figure b; Bond et al, ), respectively (Figure ). Centennial cooling (Bond‐like) events with enhanced EAWM have been reported in southern China (Wang et al, ), the East China Sea (Zheng et al, ), and the SCS (Li et al, ), which are thought to have been driven by solar activity (Bond et al, ). We interpret the PC338 record to indicate that when the EAWM increased during cold/arid stages, significant magnetic mineral coarsenings occurred, which we relate to the reduced weathering and delivery via enhanced winter currents.…”

South China Sea (SCS) sediments can provide important paleoclimate records because of their generally high deposition rates and strong regional influence of East Asian summer monsoon (EASM) variations. However, interpretation of sedimentary records from the northwestern SCS slope is complicated because sedimentation is sensitive to sea level and provenance variations. We seek to develop a paleoclimatic record of SCS sediments by analyzing sediment magnetic properties over the past ∼36 kyr from core PC338. The dominant magnetic minerals are magnetite and hematite in most parts of the core. The hematite concentration increased profoundly over the ∼15–32 kyr B.P. period when sea level was lower than −90 m below the present level. This suggests that Red River inputs were enhanced significantly in this period. Moreover, increased coarse magnetite contents were recorded in association with an enhanced East Asian winter monsoon (EAWM) during the Last Glacial Maximum and Heinrich event 1. Low‐field and frequency‐dependent magnetic susceptibility variations were coeval with EASM‐controlled climate change recorded in South China and the SCS over the past 15 kyr, probably because regional terrestrial weathering and erosion of iron‐bearing minerals, and their transportation are dominated by climate. Rhythmic coarsening of Holocene magnetic mineral concentrations coincided with global cooling events, which indicates that core PC338 also contains signals of enhanced EAWM variations. The study demonstrates that magnetic proxies are indicative of sediment supply and deposition variations on the SCS continental slope that are useful for understanding the effects of sea level and climate change on SCS sediments.

“…Finally, observation of previously thought extinct taxa suggests that these taxa are probably extant in modern time as endemic species. This is notably the case of Melitasphaeridium choanophorum which occurs in recent sediments of the Gulf of Mexico (Limoges et al 2013;Price et al, 2017b) and the South China Sea (Li et al, 2017 ), as well as Dapsilidinium pastielsii found in surface sediments from the Indo-Pacific warm pool region (Mertens et al, 2014).…”

This paper examines the distribution of 91 modern dinoflagellate cyst taxa from 3636 locations across the world's oceans. Patterns of distributions among the taxa included bipolarity, cosmopolitan, northern versus southern hemispheres, and geographically restricted. Of the 91 taxa, three dominate these assemblages at the global scale, Brigantedinium species, Operculodinium centrocarpum sensu Wall and Dale 1966 and some species of Spiniferites. Whereas Brigantedinium is a true cosmopolitan taxon, with high abundances in each ocean, Operculodinium centrocarpum sensu Wall and Dale 1966 shows high abundances in polar to temperate regions in the Northern Hemisphere, and in tropical to subtropical waters in the Southern Hemisphere. Spiniferites species show highest occurrences in the Southern Hemisphere. This study also highlights three true bi-polar species, Impagidinium pallidum, Islandinium minutum and Polarella glacialis. Only a few taxa are strictly endemic, either being relics of ancient seas such as the Paratethys (Spiniferites cruciformis) or linked to specific environmental conditions. However, recent studies have shown recent worldwide dispersal of these endemic species possibly due to human activities. Overall, this compilation has highlighted the progress made since the early 1970s on our understanding of these important tracers of environmental conditions but also gaps in our knowledge of their distribution in pelagic regions in the Pacific and Indian Oceans as well as under Arctic sea ice.
