Systematic, bed-by-bed excavations for macrofossils which were carried out in the northern Switzerland from 1970 through 1974 provided a great number of perisphinctids from the type Transversarium Zone. 1179 specimens out of this material were prepared. The greater part of the prepared specimens has been measured. 241 of the measured perispinctides were studied in detail with the aim to produce taxonomical units at the species level that can be used in time stratigraphy. The consequence of this procedure was that 56 formal perisphinctid species are described here, 23 of which are new to science. One new genus, Eoataxioceras, is proposed. There is a pronounced provincial differentiation between the ammonite faunas in England and Switzerland, but enough taxa are represented in both faunal provinces to ensure a detailed correlation at the subzone level. 171 pp., 229 figs, hc folio.…

Systematic bed-by-bed collecting from in situ measured sections and from palaeontologic excavations in the formations of the Upper Oxfordian and of the Kimmeridgian in northern Switzerlandyielded 1444, partly well-preserved perisphinctacean ammonites. 1146 of these were prepared, and most of the prepared specimens were measured. 144 of the measured perispinctaceans were studied in detail. 57 formal taxa of specific rank are described and figured in this study. Five of these are new to science. 53 formal taxa of these perisphinctaceans are figured for the first time for northern Switzerland. 233 pp., 188 figs, 80 tabs, hc folio.…

Two papers in one. 185 [133, 52] p., 30 [21, 9] plates, numerous text figures, folded chart in rear pocket, large 4to (31.0 x 23.0 cm). Pictorial laminated boards.Two monographs, both well-illustrated, on Mesozoic ammonites, the first, by Schlatter, dealing with faunas from the Lias (Trias), the second, by Gygi and von Hillebrandt, with Jurassic species. Both published together in the series, Schweizerische Paläontologische Abhandlungen, this being the whole volume 113.
