Resumo: A laboratory technique was developed to extract palynomorphs from dental calculi of South American gomphotere Notiomastodon platensis individuals. The samples were obtained from molar specimens from Northeastern and Southern Brazil. The laboratory procedure consists in steps of maceration, addition of Lycopodium clavatum exotic spores, reaction with concentrated hydrochloric acid, washing with distilled water and sonication. Glycerin gelatin was used to prepare the microscope slides containing the microfossils. Pollen grains, pteridophyte spores and fragments of plant tissues were recovered. This methodology allows the extraction and observation of other microfossils, such as phytoliths, that might also be present in dental calculi of herbivorous mammals.

As amostras foram retiradas de espécimes molares provenientes de localidades do Nordeste e do Sul do Brasil. O procedimento constitui-se em etapas de maceração, adição de esporos exóticos de Lycopodium clavatum , reação com ácido clorídrico concentrado, lavagem com água destilada e tamisação por ultrassom. A preparação das lâminas com os palinomorfos obtidos fez uso de gelatina glicerinada. Foram recuperados grãos de pólen, esporos de pteridófitas e fragmentos de tecidos vegetais. Esta metodologia permite a extração e observação de outros microfósseis, como fitólitos, que também podem estar presentes em cálculos dentários de mamíferos herbívoros.Universidade Federal do Rio de Janeiro2017-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/786810.11137/2016_1_127_132Anuário do Instituto de Geociências; Vol 39, No 1 (2016); 127-132Anuário do Instituto de Geociências; Vol 39, No 1 (2016); 127-1321982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/7868/6349Copyright (c) 2016 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMisumi, Shana YuriAsevedo, LidianeAvilla, Leonardo dos SantosBarth, Ortrud MonikaAguiar de, Marcia Barros2017-02-15T18:21:34Zoai:www.revistas.ufrj.br:article/7868Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-02-15T18:21:34Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
