| Abstract |
The dock construction works in the port of Antwerp at Doel and Kallo (prov. Oost-Vlaanderen, Belgium) have allowed the collection of a rich and diverse Pliocene bivalve fauna. It contains 182 taxa, 178 species and four subspecies. 90 species out of 178 (51%) are extinct. The rate of extinction does not significantly vary between the recognised strata, ranging from Lower to Upper Pliocene. The average longevity of the species is calculated at 10.7 Ma. This long range makes most of these bivalve species unfit for use in Neogene stratigraphy. The bathymetry of the different levels of the Pliocene is assessed, using the species still occurring in the Recent fauna (49% of the total number): it decreases towards the end of the Pliocene. |
