Describes Bouhamidoceras zizense n.g. n.sp. (belonging to the Juraphyllitidae), in different stages of development, from lower Liassic deposits of the High Atlas mountains, Morocco, and four other ammonites from middle and upper Lotharingian (Jurassic) deposits.

The Mihajlovici area in southwestern Yugoslavia is a mosaic of fault blocks produced by two sets of large faults, trending NW and NE. The horsts are lower Jurassic limestone, and the grabens are occupied by diabase-radiolarite, known as the ophiolitic series, of lower Malm age (upper Jurassic). Abundant ammonites and microfauna identify several horizons, notably the Toarcian (upper Lias, i.e., lower Jurassic) and the uppermost bed of the lower Malm, thus fixing the Malm age of the ophiolitic series.

A study of the stratigraphic and structural relationships of 23 lower and middle Jurassic fossiliferous localities, most of them reported for the first time, in the Betic cordilleras of the Malaga region, Spain. The distribution of the various paleontologically defined horizons in the different structural units is summarized in a table.
