Resumo: | Taphonomy focuses on the post-mortem processes of transport and preservation of biotic remains in the sedimentary record, and as such it has important applications for paleoenvironmental reconstructions. The aim of this work is to verify the degree of dissolution, abrasion, bioerosion and fragmentation in foraminiferal tests recovered from bottom sediments of the Parrachos de Maracajaú, Rio Grande do Norte, and to estimate the influence of these taphonomic processes in the distributon and preservation of the assemblages. Fifty-one species of benthic foraminifera have been found in the studied site. The taxonomic composition is typical of a coral reef environment. Amphistegina lessoni, Sorites marginalis, Quinqueloculina lamarckiana, Q. agglutinans, Peneroplis carinatus and Archaias angulatus are abundant in all the studied localities. The energy of the environment was interpreted as high. The species have been grouped into two groups, and the statistical data show that all four taphonomic processes (dissolution, abrasion, bioerosion and fragmentation) have influenced the distribution and preservation patterns of the foraminifera. |

O trabalho tem como objetivo verificar o grau de dissolução, abrasão, bioerosão e fragmentação nas tecas dos foraminíferos, encontrados nos sedimentos de fundo dos Parrachos de Maracajaú, Rio Grande do Norte, e estimar a influência destes processos tafonômicos no controle dos padrões de distribuição e preservação das assembléias. Foram encontradas 51 espécies de foraminíferos bentônicos, onde a composição taxonômica é típica de ambiente recifal. As espécies Amphistegina lessoni, Sorites marginalis, Quinqueloculina lamarckiana, Q. agglutinans, Peneroplis carinatus e Archaias angulatus são abundantes em todas as estações amostradas. A energia do ambiente foi interpretada como elevada. As espécies foram agrupadas em dois grupos e os dados estatísticos mostram que todos os quatro processos tafonômicos (dissolução, abrasão, bioerosão e fragmentação) influenciam em conjunto os padrões de distribuição das tecas dos foraminíferos.Universidade Federal do Rio de Janeiro2007-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/677110.11137/2007_2_92-103Anuário do Instituto de Geociências; Vol 30, No 2 (2007); 92-103Anuário do Instituto de Geociências; Vol 30, No 2 (2007); 92-1031982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6771/5368Copyright (c) 2007 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBatista, Daniele SilvaVilela, Claudia GutterresKoutsoukos, Eduardo A.
