TL;DR: X-ray microtomography is used to investigate a newly discovered sirenian petrosal from the Eocene of Tunisia, which represents the oldest occurrence of sirenians in Africa and supports their African origin.

TL;DR: In this paper, a new look at these deposits has shown a fault-controlled mosaic carbonate platform that is different from the carbonate ramp models, and the facies organization and cycle stacking pattern suggest deposition in a mosaic of intertidal islands between which sub-tidal restricted or open conditions could coexist in very close proximity.

TL;DR: Carbon and oxygen isotope profiles from a well-dated carbonate section spanning the Sinemurian time on the Caussenard High (southeast France) are compared to sedimentological data and the results from sequence stratigraphy analysis, in order to discuss the origin of isotopic variations in a shallow-marine carbonate succession as mentioned in this paper.

TL;DR: The first known embrithopod from the Eocene of Tunisia is described in this article, where an atlas, carpus and metacarpus elements, and a part of the pelvic girdle are described from Bir Om Ali, Tunisia, a new late Eocene locality.

TL;DR: In the Lodeve region of the South-East Basin, the upper Hettangian to Lotharingian carbonate series shows more than twenty sedimentary discontinuities of various types.
