The Early-Mid Holocene transition is a period of profound changes in climatic mechanisms and hydrological features in Europe and North Africa. The melting of the Laurentide ice sheet led to an oceanic and atmospheric reorganisation in the North Atlantic, while the Mediterranean underwent a major hydrological shift. The impacts on Mediterranean rivers remain unclear, as there are few records documenting responses to the 8.

The calculation of initial U/U activity ratios in all samples younger than 500 ka shows high, reasonably constant values, with an average of 5.

- The mid-Cretaceous vertebrate assemblage in south-eastern Morocco is one of the most diverse continental groups of its time, featuring a variety of bony fish including lungfish, coelacanths, and ray-finned fish.
- Recent studies have identified several lungfish species, including a new mention of Arganodus tiguidiensis, and clarified the classification of certain ginglymodians and teleosteans from the assemblage.
- The findings suggest that while this fossil ecosystem showed large body sizes and a higher average trophic level compared to modern freshwater ecosystems, it was still lower than that of current marine systems, highlighting its unique ecological characteristics.
