This flora has been recovered from 2 localities: a 39 m-thick sedimentary sequence near the village of Balcı, dominated by limestones related to well-developed, alkaline, and deep lake; and a 252 m-thick borehole (SK–2) near the village of Şarkikaraağaç, dominated by organic claystones and marls formed in a context of palustrine and shallow lake conditions. Both sequences are within the Göksöğüt Formation (upper Miocene–Pliocene). The assemblage at Balcı is dominated by gyrogonites of the genus <em>Sphaerochara</em> cf. <em>intricata</em>, <em>Chara vulgaris</em>, <em>Chara</em> cf. <em>aspera, Lychnothamnus duplicicarinatus,</em> and <em>Lychnothamnus</em> cf. <em>barbatus</em> subsp. <em>megalicarpus.</em> Gyrogonites from the lower part of the SK–2 borehole at Şarkikaraağaç are very diverse and well-preserved. The assemblage is composed of <em>Sphaerochara intricata</em>, <em>Chara vulgaris, Chara globularis, Chara</em> cf. <em>hispida, Chara</em> cf. <em>aspera</em>, <em>Nitellopsis</em> (<em>Tectochara</em>) <em>etrusca</em>, and <em>Lychnothamnus duplicicarinatus.</em> Several seeds/fruits of aquatic and helophytic plants occur associated with this charophyte flora, including <em>Ceratophyllum</em>, <em>Aldrovanda, Scirpus, Ranunculus</em> and <em>Typha</em>. The dominance of the species <em>N.</em> (<em>T.</em>) <em>etrusca</em> suggests that the base of the sedimentary sequence at Şarkikaraağaç is late Miocene, most probably Vallesian-Turolian in age. Likewise, the occurrence of <em>Lychnothamnus</em> cf. <em>barbatus</em> subsp. <em>megalicarpus</em> at the base of the Balcı sequence indicates that it probably dates back to the Turolian age. The facies assemblage and the associated fossils such as ostracods from both Balcı section and the SK–2 borehole indicate that palustrine and lacustrine conditions prevailed in the Yalvaç Basin during the late Miocene. The lake was stable, oligotrophic and oligohaline in the central part of the basin, while the water table fluctuated along the lake's edges where palustrine vegetated conditions prevailed. The species <em>N.</em> (<em>T.</em>) <em>etrusca</em> and <em>L. duplicicarinatus</em> and <em>L. barbatus</em> subsp. <em>megalicarpus</em> are being reported for the first time in Anatolia, providing significant information about the distributional pattern of these biostratigraphically significant taxa.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"332 ","pages":"Article 105221"},"PeriodicalIF":1.7,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Choteč Event, a global anoxic pulse that occurs just above the Lower-Middle Devonian boundary (392.5–393.1 Ma), has been identified within this transition. These strata are included in the Moniello and Naranco fms in Asturias and the equivalent Santa Lucía and Huergas fms in Leon. They are independently age-contrained based on conodont and invertebrate biotas. For the first time we describe palynomorph assemblages recovered from the Lower to Middle Devonian transition in Northern Spain. The assemblages contain terrestrial (spores) and marine (acritarchs, prasinophycean cysts, chitinozoans) elements, thus recording primary productivity on both the land and in the oceans. The older assemblages belong to the <em>annulatus–sextantii</em> Spore Zone and the younger assemblages the <em>douglastownensis–eurypterota</em> Spore Zone, which is concordant with the independent age constraints. Our analysis of the distribution and diversity of marine and terrestrial palynomorphs supports interpretations of the facies change associated with the Choteč Event as being related to a change to increased rainfall and terrestrial runoff. However, this change is associated with only limited taxon turnover in both land plant spores and marine phytoplankton and chitinozoans.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"332 ","pages":"Article 105222"},"PeriodicalIF":1.7,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142553842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, to make accurate interpretations and analyses using plant phytoliths, regionally-specific reference collections are warranted. There is ample research documenting phytolith morphotypes observed in grass species worldwide (due to their high phytolith production), and of dicots in tropical regions, but there is dearth of phytolith references for dicot species in temperate regions like the Pacific Northwest of North America. This study aims to fill part of this gap by documenting phytolith morphotypes observed in 60 culturally important plant foods, medicines, and textiles, all predominantly dicot species. Phytoliths are classified by abundance in specific plant parts (e.g., stem, leaf, flower) and the findings are compared to closely related species studied elsewhere. Results indicate that many of the dicot plant species in the Pacific Northwest produce more phytoliths than closely related species worldwide, likely due to differing environmental factors which affect phytolith production in plants. These findings could be useful in palaeoecological contexts to assess vegetation changes or identify dicot-dominated ecosystems, like Indigenous cultivated and managed forests and other perennial fruit tree/shrub dominated landscapes. Additionally, three of the species studied here showed possible diagnostic phytoliths but further confirmation is warranted. Future studies should consider localized environmental patterns affecting phytolith production, and therefore, our understanding of phytolith taxonomy and deposition/taphonomy.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"332 ","pages":"Article 105220"},"PeriodicalIF":1.7,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142537203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though evidence for forests at low palaeolatitudes demonstrates their emergence by the mid Devonian, sparse high-palaeolatitude records almost entirely comprise herbaceous lycopods. By the Famennian forest ecosystems are widely evidenced at low palaeolatitudes, however high latitude palaeofloras are almost exclusively represented by a single locality, the Waterloo Farm lagerstätte from South Africa (approximate palaeolatitude, 70°S). Understanding climatic and ecological conditions at this locality is doubly important as it also hosts diverse vertebrate taxa, including the only high latitude Devonian tetrapods. <em>Archaeopteris</em>, the quintessential Late Devonian woody tree, has previously been identified at this locality on the basis of leafy branch system fragments, though some uncertainty has remained as to whether these represent tree sized organisms. Here we present co-occurring large axes, including a trunk base, attributable to <em>Archaeopteris</em> trees inferred to be in excess of 20 m height, the first demonstration of forest stature at high latitudes in the Devonian. This possibly reflects high latitude climatic amelioration, resultant from warm ocean currents circulating southwards in response to progressive closure of the Iapetus Sea.
