The swimming trace Undichna from the latest Devonian Hangenberg Sandstone equivalent of Morocco-Atlas, but they are still poorly documented. Here, we describe a fossil swimming trace from strata overlying the Hangenberg

Pairing symmetry of the one-band Hubbard model in the paramagnetic weak-coupling limit: A numerical RPA study gap in a weak-coupling approach to the Hubbard model for a two-dimensional square lattice

Crustal melting and recycling: geochronology and sources of Variscan syn-kinematic anatectic granitoids of the Tormes Dome (Central Iberian Zone). A U–Pb LA-ICP-MS study of Carboniferous-inherited zircon shows that crustal recycling/cannibalization may often happen at a fast pace

The origin of the Palaeoproterozoic AMCG complexes in the Ukrainian shield: New U-Pb ages and Hf isotopes in zircon dykes. The Hf isotope ratios in the zircons indicate a predominantly crustal source for the initial

Late Carboniferous Tetrapod Footprints from the Souss Basin, Western High Atlas Mountains, Morocco (Marsh, 1894), Dimetropus (Romer and Price, 1940), and Ichniotherium (Pohlig, 1892). These footprints can
