Living isopods of the suborder Oniscidea (commonly called woodlice) are the only group of Crustacea almost entirely composed of terrestrial forms. Furthermore, woodlice are completely independent from the aquatic environment from which they originally arose. From marine ancestors, woodlice are a key taxon to study the conquest of the land among arthropods because of their interesting gradation of morphological, physiological and behavioral adaptations for terrestriality. However, the origin and… 
Terrestrial Isopods from Spanish Amber (Crustacea: Oniscidea): Insights into the Cretaceous Soil Biota
A new collection of 11 terrestrial isopod specimens preserved in Albian-aged amber from the Peñacerrada I outcrop, northern Spain, which collectively represent the most thoroughly documented fauna of Mesozoic Oniscidea, indicating that Cretaceous isopods were a group of considerable adaptive diversity, exhibiting innovations analogous to what Recent isopoda would exhibit 105 million years later.
A remarkably well-preserved terrestrial isopod (Peracarida: Isopoda: Armadillidiidae) from the upper Oligocene of Hungary, with remarks on the oniscidean taphonomy
A near-perfect preservation of the isopod's cuticular surface indicates their potential to be preserved in marine siliciclastic settings under specific conditions.
An evolutionary timescale for terrestrial isopods and a lack of molecular support for the monophyly of Oniscidea (Crustacea: Isopoda)
The results suggest that the terrestrial environment has been colonized more than once by isopods, and the monophyly of the suborder Oniscidea was not supported in any of the analyses, conflicting with classical views based on morphology.
Fossil evidence of extended brood care in new Miocene Peracarida (Crustacea) from Mexico
The first fossil evidence of extended brood care in Peracarida is described, based on two Oniscidea (Isopoda) gravid females preserved in Miocene Chiapas amber from Mexico.
Diversity of the Crinocheta (Crustacea, Isopoda, Oniscidea) from Early Miocene Chiapas amber, Mexico
This study represents the first fossil record of the family Detonidae, Olibrinidae, and “Stenoniscidae”, and the oniscidean fauna presented here supports a particularly wet paleoenvironment, under brackish water influence, similar to an estuary.
Aerial and aquatic respiration in littoral Oniscidea (Isopoda) from Southern California, USA
Examination of aerial and aquatic respiration in six species of marine-littoral Oniscidea shows that littoral species tolerate significant periods of immersion, allowing them to withstand habitat inundation during spring high tides, storm swells and, in riparian species, rainstorms and snowmelt.
Genetic evidence against monophyly of Oniscidea implies a need to revise scenarios for the origin of terrestrial isopods
This work employed the highly conserved, nuclear protein-coding genes Sodium-Potassium Pump and Phosphoenolpyruvate Carboxykinase and produced a robust and fully resolved phylogenetic tree that offers strong evidence against the monophyly of Oniscidea.
The cavernicolous Oniscidea (Crustacea: Isopoda) of Portugal
The study of subterranean Oniscidea in Portugal has been neglected for nearly 70 years, but recent investigations have revealed high diversity, and terrestrial isopods are the richest group of cave-adapted animals.
Triassic Isopoda - three new species from Central Europe shed light on the early diversity of the group
Three new species of Isopoda are described from two field sites in Europe and support the assumption that the transition from a dominance of Phreatoicidea towards the dominance of the remaining lineages of isopoda happened quite early (likely prior to the Triassic).
Lignocellulose degradation in isopods: new insights into the adaptation to terrestrial life
It is shown that CAZyme gene duplications and horizontal transfers can be involved in adaptive divergence between isopod CAZomes, providing new insights into the evolutionary processes that enabled isopods to conquer various environments, especially terrestrial ones.


Transition from Water to Land in Amphipod Crustaceans
The Amphipoda have not achieved the terrestrial independence of the Isopoda; they are restricted to a fairly narrow niche and some species have colonized grasslands but in circumstances which are not environmentally very different from leafmold.
Evolutionary adaptation of oniscidean isopods to terrestrial life: Structure, physiology and behavior
This review summarizes the present knowledge of some aspects of the morphology, physiology and behavior as it related to oniscidean adaptation to the terrestrial realm.

This new fossil evidence supports the remote ancestry of crustaceans well before the Late Cambrian and shows, along with other fossil data, that a variety of body plans already coexisted among the primitive crustacean stock.
Arthropods in amber from the Triassic Period
It is found that the abundance of amber during the Carnian is globally anomalous for the pre-Cretaceous and may, alternatively, be related to paleoclimate.
Exceptionally preserved crustaceans from western Canada reveal a cryptic Cambrian radiation
Diverse crustacean appendages of Middle and Late Cambrian age from shallow-marine mudstones of the Deadwood Formation in western Canada provide the earliest evidence for crown-group branchiopods and total-group copepods and ostracods, extending the respective ranges of these clades back from the Devonian, Pennsylvanian, and Ordovician.
The Silurian-Devonian Fossil Record of the Myriapoda

The oldest recorded terrestrial invertebrates are various small Diplopods (millepedes) from the Lower Old Red Sandstone of Britain which were probably preserved preferentially due to their robust
The ecology of Paleozoic terrestrial arthropods: the fossil evidence
It is postulated that herbivory, defined as predation on living plants, may have been rare in early Paleozoic terrestrial ecosystems, and that most primary productivity of terrestrial arthropods was diverted into higher trophic levels.
The phylogenetic position of the Isopoda in the Peracarida (Crustacea: Malacostraca)
The 18S data alone are inadequate at this phylogenetic level and the combined data provided novel hypotheses that require additional evidence from detailed morphological studies and DNA markers for confi rmation.
Morphology and evolution of respiratory structures in the pleopod exopodites of terrestrial Isopoda (Crustacea, Isopoda, Oniscidea)
It is assumed that completely internalized lungs with spiracles surrounded by a water-repellent surface microsculpture, evolved at least six times independently within the Oniscidea: in the Tylidae, Actaecia, Aphiloscia, the Eubelidae, the Armadillidae and in a taxon probably comprising Porcellionidae plus Armadillsidiidae.
Interaction and Coevolution of Plants and Arthropods during the Palaeozoic and Mesozoic
It is concluded that there is much evidence in the fossil record suggesting plant-arthropod interaction, but many more observations are required before detailed interpretations concerning cocvolution can be made.
