| By means of modernized sieving techniques 110 m3 of matrix from a gully filling in the Tegelen Clay were sieved. This yielded a good collection of small mammals, which clarifies the stratigraphic position of the Tiglian, a collection of other vertebrates, a small collection of mollusks, and a vast amount of plant material. A good collection of mollusks was made through classical collecting techniques. The faunal lists in this paper constitute a considerable enlargement of the known Tegelen fauna. Collecting is continuing, and further additions to the fauna may be expected. |

| The stratigraphical occurrence in the southern North Sea Basin of the marine bivalve genus Macoma is reviewed. New data concerning first and last appearances are presented. Especially the first appearance of Macoma balthica and the last appearances of M. obliqua and M. praetenuis are discussed. M. balthica appears in the late Middle Tiglian (Early Pleistocene). M. obliqua has been found in offshore deposits dating from the climatic optimum of the last interglacial, the Eemian. M. praetenuis occurs in deposits just underlying the Eemian deposits. The age of these underlying deposits is uncertain but may be Late Saalian/Early Eemian. Both latter species were previously considered to be extinct after the late Middle Tiglian. The age of the arrival of... |
