During the Oxfordian, sea-level rise created widespread carbonate platform deposition on the margins of Neotethys, although some areas remain poorly described. One such area is the Saharan Atlas of Algeria. Accordingly, the middle Oxfordian Theniet Et-Temar Formation at a new locality, Kef El Meleh, is described for the first time. Formed of marl/limestone cycles, 6 broad microfacies are present within the limestones, representing deposition in lagoon, shoal and nearshore environments. Whilst overall shallowing-up is evident, it is unclear if the smaller scale marl–carbonate cycles represent higher frequency shallowing-up, or allocyclic depositional patterns.

The Theniet Et-Temar Formation contains an important archive of macrofossils and microfossils. Of note at Kef El Meleh is the presence of a microfacies rich in dasycladalean algae, notably Salpingoporella annulata Carozzi, 1953. The specimens conform well to the type and subsequent descriptions. The assemblage is effectively monospecific in terms of algae, although the larger foraminifera Alveosepta jaccardi (Schrodt, 1894) is present. This record extends the knowledge of the distribution of S. annulata within Neotethys, especially within the Oxfordian, for which previous records are limited in comparison to those for the later Jurassic and Early Cretaceous.

在牛津时期，海平面上升在新特提斯洋边缘造成了广泛的碳酸盐台地沉积，尽管有些地区的描述仍然很少。阿尔及利亚的撒哈拉地图集就是这样的区域之一。因此，首次描述了位于新地点 Kef El Meleh 的牛津中部 Theniet Et-Temar 地层。由泥灰岩/石灰岩循环形成，石灰岩内存在 6 个广泛的微相，代表泻湖、浅滩和近岸环境中的沉积。虽然总体浅化是明显的，但尚不清楚较小规模的泥灰岩-碳酸盐旋回是否代表更高频率的浅化或异环沉积模式。

Theniet Et-Temar 地层包含重要的大化石和微化石档案。值得注意的是，Kef El Meleh 存在富含 Dasycladalean 藻类的微相，特别是Salpingoporella annulata Carozzi，1953。这些标本与该类型和随后的描述非常吻合。尽管存在较大的有孔虫Alveosepta jaccardi (Schrodt, 1894) ，但该组合在藻类方面实际上是单一特异性的。该记录扩展了对新特提斯层中S. annulata分布的认识，特别是在牛津纪内，与晚侏罗世和早白垩世的记录相比，先前的记录有限。
