Los foraminíferos bentónicos del estuario del Tahadart (N-O de Marruecos)

Abstract

Foraminifer assemblages from several surface samples of the Tahadart estuary, in the Atlantic coast of Northwestern Morocco, have been analysed for the first time. A total of seventy seven species have been taxonomically identified, fortytwo of which contained live specimens in the time of sampling. Dominant assemblage is composed of the species Ammonia tepida and Haynesina germanica, which are accompanied by Lobatula lobatula and Bolivina pseudoplicata in the mouth of the estuary and by Jadammina macrescens in the middle and higher marsh areas. The high diversity index and the great number of species coming from the marine shelf are indicative of the strong energy of this estuary, with an open connection to the sea, even in channels far from the coastal area
