Modelling the Late Devonian Climate: Implications for evolution and extinction [PDF]
, 2021 The Devonian period (419.2 - 358.9 Ma) was characterised by a warm greenhouse climate which transitioned towards glaciation throughout the Late Devonian. This period in Earth’s history was punctuated by repeated environmental and biotic crises.

Late Devonian (Famennian) Chondrichthyes from Mexico [PDF]
Journal of Vertebrate Paleontology, 2019 The Paleozoic vertebrate fossil record from Mexico is very scarce and strongly biased by rock exposure, composed mainly of upper Paleozoic (Carboniferous and Permian) outcrops (e.g., Sánchez-Zavala et al., 1999; Poole et al., 2005; González- Rodríguez et al., 2013).

Metamorphic Remnants of the Variscan Orogeny across the Alps and Their Tectonic Significance
Geosciences, 2023 Lithospheric slices preserving pre-Alpine metamorphic imprints are widely described in the Alps. The Variscan parageneses recorded in continental, oceanic, and mantle rocks suggest a heterogeneous metamorphic evolution across the Alpine domains.

The swimming trace Undichna from the latest Devonian Hangenberg Sandstone equivalent of Morocco
Swiss Journal of Palaeontology, 2021 Trace fossils occur in several strata of the Devonian and Carboniferous of the eastern Anti-Atlas, but they are still poorly documented. Here, we describe a fossil swimming trace from strata overlying the Hangenberg Black Shale (correlation largely based
