“…The pellet deriving from the decalcification step was employed to evaluate the presence of microparticles by OM (ZEISS Axio Observer 7 equipped with polarised filters and Zen imaging software 2.6, operating at different magnifications). Starch granules, palynomorphs, NPPs, and palynodebris elements were identified on morphometric features, grouped into preliminary types based on a shared morphology, and described using conventional nomenclature 23 , 142 . Each microparticle was measured in triplicate.…”

Looking for a biological fingerprint relative to new aspects of the relationship between humans and natural environment during prehistoric times is challenging. Although many issues still need to be addressed in terms of authentication and identification, microparticles hidden in ancient dental calculus can provide interesting information for bridging this gap of knowledge. Here, we show evidence about the role of edible plants for the early Neolithic individuals in the central Apennines of the Italian peninsula and relative cultural landscape. Dental calculi from human and animal specimens exhumed at Grotta Mora Cavorso (Lazio), one of the largest prehistoric burial deposits, have returned an archaeobotanical record made up of several types of palaeoecological proxies. The organic fraction of this matrix was investigated by a multidisciplinary approach, whose novelty consisted in the application of next generation sequencing to ancient plant DNA fragments, specifically codifying for maturase K barcode gene. Panicoideae and Triticeae starches, together with genetic indicators of Rosaceae fruits, figs, and Lamiaceae herbs, suggested subsistence practices most likely still based on wild plant resources. On the other hand, pollen, and non-pollen palynomorphs allowed us to outline a general vegetational framework dominated by woodland patches alternated with meadows, where semi-permanent settlements could have been established.

“…The photomicrographs and microfossil taxonomical records of the three GCs published by Adojoh et al (2017Adojoh et al ( , 2019, other non-pollen proxies, and some selected key pollen/vegetation proxies are used to establish the link between vegetation dynamics and landscape evolution of the Niger Delta. The three GCs record remarkably similar changes in the different proxies and two main phases of sedimentation were distinguished (Figures 3-5).…”

“…The deltaic configuration has experienced broad progradation (circa 300 km) since the Palaeocene, with a maximum sediment thickness of approximately 12 km, and a surface area of 140,000 km 2 (Doust and Omatsola, 1990;Stacher, 1995;Reijers, 2011;George et al, 2019; Figure 2). In addition, past investigations of marine core sediments obtained from the Niger Delta suggest that changes in the riverine input during the Late Quaternary were linked to global glacial-interglacial cycles (e.g., Riboulot et al, 2012;Adojoh et al, 2017Adojoh et al, , 2019Adeonikpekun and Sowunmi, 2019). Periods of warm temperature over Greenland were found to be associated with enhanced river discharges in West Equatorial Africa and conversely, cold conditions were related to weak river input (Shannahan et al, 2007;Weldeab et al, 2007;Miller and Gosling, 2013;Adojoh et al, 2017, Adeonikpekun andSowunmi, 2019).…”

This study presents the results of a comprehensive qualitative and quantitative palynological analysis of four shallow boreholes (Epe-1, Olokonla-1, Ikoyi-1 and Badore-1) in the lower Eocene–upper Oligocene periods of the Dahomey Basin, southwestern Nigeria. The lithostratigraphic analysis revealed three lithologies (sandy-shales, shaly-sands and sandstones). Two most important palynological zones, the Verrucatosporites usmensis, as well as the Magnastriatites howardi Pan-tropical zones, are delineated. First Appearance Datum (FAD) of Achomosphaera alcicornu marked the late Eocene–early Oligocene boundaries (E/O) within the four boreholes, while FAD of Adnatosphaeridium multispinosum defined the late Eocene–early Oligocene boundary (E/O) in Ikoy-1. Two informal palynological assemblage zones were revealed in the four boreholes. Common occurrences of palms, mangrove, fresh water and brackish water pollen, and pteridophyte spores with spots records of marine elements and algae species during marine invasion suggested fluctuation from fluvio-deltaic/nearshore to marginal marine paleoenvironments. Graphic correlation discloses that for every meter of sedimentary rock accretion within Epe-1, equally amounted to merely 0.31 m, 0.56 m, as well as 0.47 m of sediments, which were put down in Olokonla-1, Ikoyi-1, as well as Badore-1, respectively. These comparative rates of sedimentary rock accretion show with the purpose of either there is fewer attrition occurrence and/or extra accommodation gap within Epe-1 than Olokonla-1, Ikoyi-1, as well as Badore-1. The assessment of the slopes, intercept and correlation equations through graphic correlation procedures enable the identification of four biostratigraphic events in Epe-1, Olokonla-1, Ikoyi-1, as well as Badore-1. The findings in this investigation are necessary for depositional succession and paleoenvironmental understandings, as well as basin investigation, and above all, to show a relationship of broadly separated boreholes.
