Micropalaeontological investigations of the Bouhedma Formation in the Jebel Majoura section from the southern Central Tunisian Atlas revealed four successive ostracod associations (in total 16 species of 13 genera) of higher palaeoenvironmental, and thus far limited biostratigraphic and palaeobiogeographic utility due to poor preservation. The most notable of these is a new upper Hauterivian?–Barremian non-marine Wealden-type ostracod assemblage of high diversity from the Lower Member of the Bouhedma Formation, the first one documented from the southern Central Tunisian Atlas, which consists of 9 species: Cypridea cyrtorostralis, Cypridea aff. tenuis, Cypridea aff. insulae, Cypridea sp., Theriosynoecum cf. fittoni, Vecticypris polita, Alicenula? leguminella, as well as Klieana sp. and Fabanella sp. The subsequent two ostracod assemblages from the Lower Member are characterized by the brackish species Rehacythereis? sp., Fabanella sp., Ilyocypris sp., and Schuleridea? sp. indicating transition to lagoonal environment. The subsequent ostracod assemblage from two levels of the Middle Member of the Bouhedma Formation is exclusively composed of the euryhaline marginal marine Paracypris sp., and the marine species Antepaijenborchella praealta, Protocythere cf. bedoulensis and Metacytheropteron aff. grosdidieri, reflecting a marine incursion event.

The biostratigraphic utility, particularly that based on the non-marine fauna, is limited thus far but the results are consistent with an upper Hauterivian?–Barremian age previously assigned to the Bouhedma Formation from the southern Central Tunisian Atlas, facilitating its regional stratigraphic correlation with coeval series from the northern part of this palaeogeographic domain.

The discovery of Tunisian Wealden-type non-marine ostracods from the southwestern margin of the Tethys (North Africa) sheds new light on the dispersal patterns and palaeobiogeography of these ostracods, their potential utility as biostratigraphic tool, as well as on the significance of the north Gondwanan continental basins and peri-Tethyan islands of the Central Tunisian Atlas for recording Early Cretaceous non-marine microfaunas and -floras.

对突尼斯中南部地图集 Jebel Majoura 部分的 Bouhedma 组的微古生物学调查揭示了四个连续的介形动物协会（总共 13 个属的 16 种）具有较高的古环境，迄今为止由于保存不佳而限制了生物地层学和古生物地理用途。其中最值得注意的是一个新的上 Hauterivian?-Barremian 非海洋 Wealden 型介形动物组合，来自 Bouhedma 组下部的高度多样性，这是第一个记录在突尼斯中南部地图集的南部，由 9 个物种组成：Cypridea cyrtostralis , Cypridea aff. 细叶，Cypridea AFF。街坊，Cyprideasp.，Theriosynoecum cf. fittoni , Vecticypris polita , Alicenula ? 豆科植物，以及Klieana sp。和Fabanella sp。随后来自下层成员的两个介形虫组合的特征是微咸物种Rehacythereis ? sp., Fabanella sp . , Ilyocypris sp., 和Schuleridea ? sp. 表明过渡到泻湖环境。随后来自 Bouhedma 组中段两层的介形虫组合完全由广盐性边缘海相Paracypris 组成sp.，以及海洋物种Antepaijenborchella praealta，Protocythere参见。Bedoulensis和Metacytheropteron aff。grosdidieri，反映了一次海洋入侵事件。

生物地层学实用性，特别是基于非海洋动物群的生物地层学用途，迄今为止有限，但结果与先前分配给来自突尼斯中南部阿特拉斯的 Bouhedma 组的上 Hauterivian?-Barremian 时代一致，促进其区域地层相关性来自这个古地理区域北部的同时代系列。
