Some taxa previously described are revised here and 42 new angiosperm leaf morphotypes/taxa are described. The Climate Leaf Analysis Multivariate Program (CLAMP) is applied to assess the palaeoclimate. An update of the tool to assess the most suitable modern climate CLAMP calibration dataset is introduced. The Integrated Plant Record (IPR) vegetation analysis, assessing the most likely major vegetation type represented by a fossil flora, and similarity approaches Drudges 1 and 2, indicating the most similar modern vegetation proxies, had been previously applied to data from Parschlug. Both are again applied here on the enlarged floristic spectrum. The results indicate “sclerophyllous subhumid forest” as the most likely major zonal vegetation type for Parschlug and European vegetation, namely “Thermophilous mixed deciduous broadleaved forests”, distributed today in southern and southeastern Europe, as the most similar modern vegetation. The climate for Parschlug, inferred from CLAMP and the climate in the region of the modern vegetation proxies, indicates distinct seasonality in precipitation and temperature.","PeriodicalId":12431,"journal":{"name":"Fossil Imprint","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69921724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This new plant is characterized by both macromorphological and some microstructural features. Taimyria triassica has long racemose aggregations (cones or megastrobili) consisting of an axis with peltate seed-bearing discs (which also can be interpreted as seed-bearing semi-closed capsules), with margins curved adaxially. The seed-bearing discs are round to ovoid, with short stalk connected at central area of the adaxial part, and attached to the cone axis nearly perpendicularly, in a dense spiral pattern. Six to eight seeds are concentrically displayed around the stalk on the adaxial surface of the discs. The seeds preserved in seed-bearing discs were extracted from macerated reproductive organs and described as well. The seeds are platyspermic, ovoid, narrower at their apical micropylar end orientated toward the disc stipe. Problems of systematics and general evolutionary trends of the order Peltaspermales are briefly discussed.","PeriodicalId":12431,"journal":{"name":"Fossil Imprint","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69922429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One mandible fragment, three isolated teeth and a pedal phalanx collected from the Pelion Member (base of the formation aged 5.0–4.5 Ma) are compatible in dimensions with Orrorin tugenensis and Ardipithecus ramidus whilst a mandible from the Sinibo Member, a younger level in the formation (ca. 3.4–3.0 Ma) represents an appreciably larger species, as big as, or bigger than, Praeanthropus afarensis (ex-Australopithecus afarensis) from locality AL 333, Ethiopia. The small hominid mandible and an isolated p/3 were found in the type section of the Mabaget Formation at localities 2/211 and 2/210 respectively, in deposits aged ca. 5.0–4.5 Ma. An isolated upper milk molar, a lower third molar and a pedal phalanx are from Sagatia, near Rondinin, also aged between 5.0 and 4.5 Ma. The large mandible was collected at Sinibo, near Kipcherere, from sediments above the local occurrence of the Tulu Bor Tuff (= Sidi Hakoma Tuff) which is dated at 3.446 Ma. The aim of this paper is to describe and interpret these hominid fossils and to place them within their geological, stratigraphic and palaeoenvironmental contexts.","PeriodicalId":12431,"journal":{"name":"Fossil Imprint","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69922555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, even commonly used solutions may be too harsh for the preparation of extremely delicate cuticles. Here we offer a step-by-step protocol for the preparation of fragile conifer cuticles using sodium hypochlorite, otherwise known as household bleach. Conifer needles from the Miocene lignites of the Adendorf and Hambach open-mine pits in western Germany were prepared using a mild solution of this oxidizing agent. The cuticles had proven to be too fragile for most maceration chemicals, including Schulze’s reagent, which even disintegrated the cuticles that were given a protective coating. However, it was discovered that trimming the leaf margins and damaged areas prior to a short exposure to 5–10% sodium hypochlorite solution resulted in the good preparation of the cuticle. Furthermore, this modified method allowed for the preparation of large areas of leaf. While this procedure may not be suitable for all cuticles, it is offered here as an easy and gentle method for preparing extremely delicate conifer cuticles that are destroyed by other chemicals and protocols.","PeriodicalId":12431,"journal":{"name":"Fossil Imprint","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69922509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
