Aspectos neoicnológicos dos sedimentos da plataforma do Amazonas

Abstract

Several biogenic structures collected by box core samples in the Amazon Shelf sediments were described morphologically and classified in an ethological point of view. The biogenic structures are associated with ecological data from CTD analyses, such as luminosity, oxygen concentration, temperature and salinity. The present study summarizes the main ichnological aspects observed in the sediments of this area and the organisms which are more active in the biogenic reworking.
