This paper analyses and describes the benthic foraminiferal community associated with this well-preserved Pleistocene <em>P. oceanica</em><span> meadow, with the purpose of testing the usefulness of foraminifera as an Indirect Palaeo-Seagrass Indicator (IPSI), providing both qualitative and quantitative parameters to recognize other meadow-related environments where fossil remains of seagrasses are not preserved. Despite being influenced by some diagenetic processes that might have affected the foraminiferal assemblage, the Fauglia succession represents a suitable setting for testing benthic foraminifera as IPSI in a temperate environment. Considering this limitation, together with other ecological constraints such as seawater temperature, this study provides evidence of the high potential of benthic foraminifera as IPSI. Several parameters such as the modified Foraminifera Index (FI’), the “long vs. short life-span index” (I</span></span><sub>LS</sub>), and the presence of permanently attached, encrusting foraminifera were tested. New indexes were also developed, namely the K/R ratio, consisting of the ratio between keeled <em>Elphidium</em> and the sum of rounded elphidiids (e.g., <em>Elphidium translucens</em>, <em>Cribroelphidium</em>, <em>Porosononion</em>) and <em>Haynesina</em>, and the K/R<sub>EXT</sub> ratio, consisting of the ratio between keeled <em>Elphidium</em> and the sum of rounded elphidiids, <em>Haynesina</em> and other related genera that display a rounded periphery (i.e., <em>Astrononion, Melonis, Nonion, Nonionella, Valvulineria</em><span>). All these indexes were examined, suggesting their potential use for recognizing seagrass-related palaeoenvironments. The K/R</span><sub>EXT</sub><span> ratio (and K/R) in association with the presence of permanently attached foraminifera revealed to be the most reliable palaeo-seagrass indicators, suggesting that this combination could be very useful also in other case studies where diagenesis altered the foraminiferal association.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Testing an indirect palaeo-seagrass indicator: benthic foraminifera from the Lower Pleistocene <i>Posidonia</i> meadow of Fauglia (Tuscany, Italy)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-26 01:31:51.164571","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Posidonia oceanica, Elphidium, Quaternary, IPSI, Paleoenvironmental reconstructions, Taphonomic biases","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-08-12","DateCreate":"2022-08-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000800588500001","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.marmicro.2022.102126"},"refs":null,"anarec":{"AnaID":354826,"PubliDate":2022,"Pagination":"102126","XtraPublOfAnaID":null,"ISBN":null,"Volume":"173","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43516,"SerRR":"Marine Micropaleontology.
