Marine bivalves such as oysters and scallops secrete calcified shells as a supporting frame for their soft bodies and for protection from predators1,2, which is thought to be one of the key factors that trigger the expansion of bivalves at the dawn of the Cambrian times16. The early shell formation of bivalve larvae requires sufficient […] More
Study area The study was conducted upstream of the tidal area of the Gironde estuary (45°02′45.80″ N, 0°36′41.56″ W), where the Dordogne and Garonne rivers discharge (Southwestern France, Fig. 4). The Garonne-Dordogne hydrographic network hosts one of the largest populations of sea lamprey in Europe20,28. The Dordogne River runs over 475 km (mean flow = 216 m3/s) […] More

Samples of stone tools from the site are routinely screened with optical light microscopy. Previously, individual twisted plant fibres, some of which were multicellular, were reported on stone tools from Abri du Maras6. The authors suggested that these might be remnants of cordage, but the remains were too fragmentary to be conclusive. During further screening […] More
