Abstract

The sequence of Miogypsina species in the type region of the Aquitanian-Burdigalian offers a good basis for correlation. Early Aquitanian corresponds to the range of M. gunteri, early Burdigalian to those of M. irregularis and M. burdigalensis, early Vindobonian to that of M. cushmani. In the western Mediterranean area application of this sequence is considered justifiable. Comparison with the similar sequence in America shows a much older occurrence of equivalent species in the western hemisphere than in Europe. A correction of the American time scale is considered premature when made on the Miogypsinidae alone.
