Evidence for terrestriality in early tetrapods is fundamentally contradictory. Fossil trackways attributed to early terrestrial tetrapods long predate the first body fossils from the Late Devonian.

Late Mid Devonian Sawdonia (Zosterophyllopsida) from Venezuela [PDF]
Premise of research. Fossil plants from the Late Middle to early Late Devonian age Campo Chico Formation, Sierra de Perijá, western Venezuela, are determined to represent a new species of the zosterophyll genus Sawdonia. While mentioned in previous publications, this plant has not been previously described or formally named.

Extent and duration of marine anoxia during the Frasnian– Famennian (Late Devonian) mass extinction in Poland, Germany, Austria and France [PDF]
– The intensity and extent of anoxia during the two Kellwasser anoxic events has been investigated in a range of European localities using amultidisciplinary approach (pyrite framboid assay, gamma-ray spectrometry and sediment fabric analysis).

A new Late Devonian genus with seed plant affinities. [PDF]
Many ovules of Late Devonian (Famennian) seed plants have been well studied. However, because few taxa occur with anatomically preserved stems and/or petioles, the vascular system of these earliest spermatophytes is little understood and available data come mostly from Euramerica.

Clay mineralogy, chemistry, and diagenesis of late devonian K-bentonite occurrences in northwestern Turkey [PDF]
Thin beds of tephra (K-bentonites) formed by the diagenesis of volcanic ash are exposed within the limestone-dolomitic limestone successions of the Yilanli formation at Zonguldak and Bartin in northwestern Turkey.
