The ornamentation of the spores is verrucate, verrucate-tuberculate, rugate or reticulate. The most abundant morphology is the verrucate ornamentation. The exospore and the perispore form the ornamentation of the spores. In most of the species analyzed abundant spheroids, variable in size were observed irregularly distributed on the spore surface, even on the laesura. This study describes and illustrates the spores of some species for the first time. The results are discussed with a recent phylogeny of the genus.</p></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"326 ","pages":"Article 105127"},"PeriodicalIF":1.9,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140901021","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}

They are calculated using a 3D-multivariate model based on data obtained by Fourier transform infrared (FTIR) spectroscopy and trait relationships linking density and the properties mentioned above. Samples have a predominantly aromatic chemical composition with variable carbonyl contents. The chemical groups detected are associated with diagenetically-resistant molecules, possibly including lignins, phenylpropanoids, tannins, and resin-like compounds. The results indicate that these plant taxa may have allocated variable amounts of resources (metabolic costs) for the development of aromatic, biomechanically resistant, and relatively long-lived foliar tissues. The determined chemical, biomechanical, and physiological properties of these leaves suggest their potential as a food source for herbivores. Thus, <em>S. tigrensis</em> leaves might have been unpleasantly astringent, difficult to eat and digest due to their hard tissues, and possibly even hazardous. Conversely, the leaves of <em>G. tigrensis</em>, <em>P. ornata</em>, <em>R. orlandoi</em>, and <em>P. micropapillosum</em> may have been easy to eat due to their softer tissues, offering food of intermediate-high nutritional value.
