The unevenly distributed remains of Pleistocene mammals in Belgium are discussed in relation to their taphonomy. Apart from a mixed (terrestrian-marine) ’fauna’ from the late Pliocene (Antwerp) and some isolated antler finds supposed to be between 2.5 and 1 million years old, the large majority of Pleistocene fossils is of Weichselian age. Within this category three groups can be distinguished: 1) Scattered finds from aeolian deposits in the lowlands, 2) Cave faunas and 3) Concentrations of large plant eaters from the Scheldt river valley. The first of these is poor in fossils because of unfavourable taphonomic conditions, whereas the second is abundant, though puzzling because of the lack of material older than Late Pleistocene ( with the one exception of Sprimont; CORDY 1981). The third group is considered remarkable for the rare occurrence of puparia of Protomorphia terraenovae (ROBINEAU-DESVOIDY, 1830) in bone cavities.
