TLDR
The centipedes and possible insects found at a new fossil site near Gilboa, New York, may represent the earliest records known for these groups of terrestrial arthropods.Abstract:
A new fossil site near Gilboa, New York, is one of only three where fossils of terrestrial arthropods of Devonian age have been found. The new Gilboan fauna is younger than the other two but richer in taxa. Fragmentary remains and nearly whole specimens assigned to Eurypterida, Arachnida (Trigonotarbida, Araneae, Amblypygi, and Acari), Chilopoda [Craterostigmatomorpha(?) and Scuterigeromorpha(?)], and tentatively to Insecta (Archaeognatha) have been found. The centipedes and possible insects may represent the earliest records known for these groups.read more

An Insect Molecular Clock Dates the Origin of the Insects and Accords with Palaeontological and Biogeographic Landmarks
TL;DR: The study defines a robust nucleotide and amino acid mitochondrial molecular clock encompassing five insect orders, including the Blattaria, and explores Tilyard's theory proposing that the terrestrial transition of the aquatic arthropod ancestor to the insects is associated with a particular plant group (early vascular plants).

Molecular timetrees reveal a Cambrian colonization of land and a new scenario for ecdysozoan evolution.
TL;DR: A timescale of ecdysozoan evolution is presented based on multiple molecular data sets, the most complete set of fossil calibrations to date, and a thorough series of validation analyses, which converge on an Ediacaran origin of all major ecdy sozoan lineages.

Mechanisms of Microarthropod-Microbial Interactions in Soil
TL;DR: This chapter provides an overview of the mechanisms of microarthropod by focusing on the microbial interactions in soil, and examines how dispersal and selective grazing in the rhizosphere affect the distribution and abundance of fungi in soil.

Functional morphology of the prosoma of Baltoeurypterus tetragonophthalmus (Fischer) (Chelicerata: Eurypterida)
TL;DR: The limb arrangement and joint mechanisms of Baltoeurypterus are intermediate between those of the xiphosurans and the arachnids, and it is possible that a sister relationship exists between the eurypterids and someArachnid groups, which would render Merostomata and Arachnida unnatural assemblages.

The oldest vascular land plants: A note of caution
TL;DR: The oldest fossil proven to be a vascular land plant is Cooksonia, from the Pridolian Stage of the Silurian Period in Wales, and it is pointed out that these microfossils may originate from algae, bryophytes, or groups now extinct or from animals.

The earliest vascular land plants: continuing the search for proof
TL;DR: The Cooksonia genus is considered to be a vascular plant from evidence at younger (Eř;eoli/Downton) horizons, and although no tracheids have been isolated from the Bringewoodian specimens, on the basis of comparative morphology they are concluded to be the oldest recorded tracheophytes.
