Ants exhibit a plethora of ecological interactions with terrestrial plants. These interactions are broadly surveyed in modern ecosystems, but are much more difficult to unveil in the fossil record. Here, we report a unique ant–conifer association preserved in an opaque piece of 100‐million‐year‐old amber from Charentes in Western France, revealed by propagation phase‐contrast X‐ray synchrotron microtomography...
Fragments of filled wood‐borings were recently discovered from the Eocene–Oligocene Conglomerate and Sandstone Formation of the Malzieu Basin (Lozère, southern France). Propagation phase‐contrast X‐ray synchrotron microtomography (PPC‐SRμCT) was used to characterize their hidden inner structures. Virtual 2D sections and 3D reconstructions show that the inner microstructures of borings display a mudstone–wackestone...
Here, we report flint nodules bearing fossil plant inclusions from the early Cenomanian of the Font‐de‐Benon sand quarry, between the villages of Archingeay and Les Nouillers, Charente‐Maritime, western France. The broken‐open surfaces of these dense siliceous rocks only partly show the whole diversity, which is established using a non‐destructive, multi‐scale approach based on propagation phase‐contrast...
