The tracks left by organisms are among the most difficult of fossils to interpret. But just such evidence puts debate about the origins of four-limbed vertebrates (which include ourselves) on a changed footing. 
Tetrapods and the Invasion of Land
The Devonian gives the first widespread evidence for nonmarine conditions and is remarkable for evidence of the colonization of land as well as freshwater rivers and lakes by both plants and fishes.
The origin of terrestrial isopods (Crustacea: Isopoda: Oniscidea)
TLDR
A pre-Pangaean origin of the Oniscidea is discussed and supported, in the Late Paleozoic—most likely during the Carboniferous, to replace this group in a deep-time context.
Do mudskippers and lungfishes elucidate the early evolution of four-limbed vertebrates?
TLDR
It is concluded that mudskipping ‘walking fishes’ (Periophthalmus sp.) and Dipnoi shed light on the gradual evolutionary transition of ancient fishes to early tetrapods that occurred during the Devonian in muddy, salty waters.
Sequences, stratigraphy and scenarios: what can we say about the fossil record of the earliest tetrapods?
TLDR
The Polish trackways force a substantial reconsideration of the nature of the early tetrapod record when only body fossils are considered, and it is found that 95 per cent credible and confidence intervals for the origin of digit-bearing tetrapods extend into the Early Devonian and beyond.

ABSTRACT The hypothesis that tetrapods evolved from elpistostegids during the Frasnian, in a predominantly aquatic context, has been challenged by the discovery of Middle Devonian tetrapod trackways
Geology, Paleoclimatology and the Evolution of the Kidney: Some Explorations into the Legacy of Homer Smith
TLDR
An overview of the relation between kidney development in different species and new developments in plate tectonics and paleoclimatology is performed, which likely had a remarkable effect on evolution.
APPLICATIONS OF EXPERIMENTAL NEOICHNOLOGY TO PALEOBIOLOGICAL AND EVOLUTIONARY PROBLEMS
It is semi-traditional at PALAIOS for the outgoing editor to provide a Spotlight article as their tenure as editor ends. Past editors have pontificated on the state of the journal, its ranking, and

TLDR
Evidence of lumbering movement indicates that these giant arthropods, now extinct, could survive out of water at a time when the earliest tetrapods were making their transition to the land.
Tetrapod trackways from the early Middle Devonian period of Poland
TLDR
Well-preserved and securely dated tetrapod tracks from Polish marine tidal flat sediments of early Middle Devonian (Eifelian stage) age are presented, forcing a radical reassessment of the timing, ecology and environmental setting of the fish–tetrapod transition, as well as the completeness of the body fossil record.
An exceptional Devonian fish from Australia sheds light on tetrapod origins
TLDR
New observations from the most complete, acid-prepared Devonian tetrapodomorph fish yet discovered, Gogonasus are presented, which was previously placed just crownward of Kenichthys and rhizodontids, the most primitive taxa on the tetrapOD lineage.
The origin of the internal nostril of tetrapods
TLDR
New material of Kenichthys, a 395-million-year-old fossil fish from China, is presented that provides direct evidence for the origin of the choana and establishes its homology: it is indeed a displaced posterior external nostril that, during a brief transitional stage illustrated by KenichThys, separated the maxilla from the premaxilla.
The pectoral fin of Tiktaalik roseae and the origin of the tetrapod limb
TLDR
The pectoral appendage of a member of the sister group of tetrapods, Tiktaalik roseae, is described, which is morphologically and functionally transitional between a fin and a limb.
