Acta Geologica Polonica, 67 (1), 31–46. Warszawa. A juvenile specimen of the ammonite Pseudaspidoceras from the Early Turonian of the Goulmima area in the Province of Er-Rachida in south-eastern Morocco shows clear evidence of predation by a tooth-bearing verte- brate. Most of the body chamber is missing, as a result of post-burial compactional crushing. The adapertural part of the shell on the left flank of the surviving fragment of body chamber bears six circular punctuations; the right flank four. These are interpreted as the product of a single bite by a mosasauroid, probably aTethysaurus . -
The Geology of the Site of the Bodleian Extension in Broad Street
The Geology of the Site of the Bodleian Extension in Broad Street By. W. J. ARKELL HE preliminary excavation for the Bodleian extension involved the removal of the greatest quantity of subsoil (' rock' in the geologist's sense) T ever taken out of one hole within the City of Oxford. The material was of two kinds, classified by geologists as • Superficial,' of Quaternary age, consisting of gravel laid down by the River Thames in Lower Middle Palaeolithic times (a few tens of thousands of years ago), and • Solid,' of Jurassic age, forming the foundation or country~rock, consisting of marine sediments deposited something like '30 million years ago. Both deposits contained fossil remains of animals which were alive at the time the rocks were formed and are of sufficient interest to put on record. The excavation as a whole was about 23 ft. deep. The highest 20 ft., approximately, was dug in Thames gravel, and the last two or three feet in the solid Oxford Clay underneath. The line of separation between the two was sharply defined and undulated only slightly, the surface of the Oxford Clay varying in elevation by only ,-,! ft. The lowest 1-2 ft. of the gravel was saturated with water, which rose to about 3- 4 ft. above the surface of the clay in the trial holes. In the bottom of the huge tank so formed, several pits were dug for founda tions. These exposed on an average 5 ft. and a maximum of 6 ft. 6 ins. of Oxford Clay (measured from the base of the gravel). -

The genus Melendezia Fernändez Lopez 1985 is treated as a junior synonym of Phlycticeras. Two new species of Phlycticeras are introduced: P. scheurlenae nom. nov. pro Ammonites pustulatus giganteus Quenstedt from the Late Bathonian (Orbis Zone), and P fuerstenbergi n. sp. from the Early Callovian (Koenigi Zone, suhcostarius horizon). The latest hitherto known species of Phlycticeras is P. waageni Buckman from the Late Callovian (Ath- leta Zone, Trezeense Subzone). A lectotype is designated for P. pustulatum (Reinecke). New biostratigraphic and morphological data underline the hitherto proposed dimorphic couple Phlycticeras Hyatt - Oecoptychius Neumayr. Both dimorphs are recorded from the Garantiana Zone up to the basal Athleta Zone. -

Introduction Coming from the Schwabenalb (Swabian Alb) a visitor will discover in the Frankenalb (Franconian Alb) certain changes of lithology within the rocks of the Jurassic System. These changes are caused by the more marginal Situation of Franconia within the South German basin compared with the central position of Suebia; they are of various intensity during the different stages of the Jurassic System (Zeiss 1968a). Strong differences are developed in the Hettangian, Sinemurian, Lower Pliens- bachian, Upper Aalenian, Oxfordian, Kimmeridgian, and Tithonian stages. Above the Hettangian, these differences are concerning especially the Middle and Southern Frankenalb (see fig. 1). The Northern Frankenalb has had often closer relations to Suebia, documented by marls and clays as prevailing Sediments, in contrast to the predominating limestone deposits of the Middle and Southern Frankenalb. Of course the limits between these areas are not fixed strictly and may shift to some degree from time to time.
