A rich and diverse plant assemblage has been excavated from latest Devonian (Famennian) black shales of the Witpoort Formation (Witteberg Group) at Waterloo Farm, close to the city of Grahamstown (South Africa). Several specimens of a new sphenopsid have been collected. The description of this as a new taxon, here named Rinistachya hilleri, gen. et sp. nov., provides an important addition to the scarce early record of the group. Rinistachya hilleri presents a novel architecture that include… 

Description of two new miniature species of Hylopanchax Poll & Lambert, 1965 (Cyprinodontiformes: Procatopodidae) from northeastern Gabon, with an updated diagnosis of the genus based on morphology, colouration and osteology.

TLDR
The presence of a truncate and slightly downwards directed anterior process of the angulo-articular and a guitar-shaped lachrymal with both its anterior and posterior margins sharply curved are herein considered as diagnostic features of Hylopanchax.

A new Late Devonian flora from Sonid Zuoqi, Inner Mongolia, northeastern China

Abstract. The Silurian and Devonian plant fossil record is the basis for our understanding of the early evolution of land plants, yet our appreciation of early global phytogeographic evolution has

Following the Mangroves: diversification in the banded lampeye Aplocheilichthys spilauchen (Duméril, 1861) (Cyprinodontiformes: Procatopodidae) along the Atlantic coast of Africa

TLDR
A pattern of diversification within a lineage of brackish water fish that is concordant with the historical distribution of coastal mangroves forests is reported, shaped by a series of historical events that likely affected forest cover since the middle Miocene.

A new species rises from beneath Florida: molecular phylogenetic analyses reveal cryptic diversity among the metapopulation of Crangonyx hobbsi Shoemaker, 1941 (Amphipoda: Crangonyctidae)

TLDR
Morphological analyses support the molecular analyses, revealing the presence of several taxonomically significant differences between the two species, including presence/absence of calceoli on the second antennae of males and differences in telson shape in both sexes.

Estuarine fish and tetrapod evolution: insights from a Late Devonian (Famennian) Gondwanan estuarine lake and a southern African Holocene equivalent

TLDR
Correlation of tetrapods (and elpistostegids) with fish nursery areas in the Late Devonian lends strong support to this hypothesis, suggesting that adaptations permitting improved access to the abundant juvenile fish within the littoral zone of estuarine lakes and continental water bodies may have been pivotal in the evolution of Tetrapods.

Rotafolia songziensis gen. et comb. nov., a sphenopsid from the Late Devonian of Hubei, China

TLDR
Although Rotafolia songziensis closely resembles Hamatophyton verticillatum in axis character, leaf morphology and primary xylem type, they are quite different in strobilar structure.

Further Study of the Late Devonian Sphenopsid Hamatophyton verticillatum from China

TLDR
It is shown that sporangial stalks at nodes of the fertile axis lack bracts, which indicates that this plant may represent the most primitive type in the Sphenopsida and, further, may prove the greater reproductive diversity of thesphenophyllales.

Fossil juvenile coelacanths from the Devonian of South Africa shed light on the order of character acquisition in actinistians

TLDR
It is argued that Serenichthys, like Rhabdoderma, was using the sheltered estuarine environment as a nursery, and is resolved as the sister group of Holopterygius and all known post-Devonian coelacanths.

IBYKA AMPHIKOMA, GEN. ET SP. N., A NEW PROTOARTICULATE PRECURSOR FROM THE LATE MIDDLE DEVONIAN OF NEW YORK STATE

TLDR
Ibyka is placed in a new order, Ibykales, close to the Hyeniales (protoarticulates) and to the Pseudosporochnales all three of which probably evolved from Trimerophytina.

TLDR
The new genus and species, Gondwanascorpio emzantsiensis, are described on the basis of fragments from the Famennian (Late Devonian) Waterloo Farm locality near Grahamstown, Eastern Cape, South Africa, providing the first evidence of Palaeozoic scorpions from Gondwana.

Reconsidering Differences between Cladoxylopsida and Iridopteridales: Evidence from Polyxylon australe (Upper Devonian, New South Wales, Australia)

TLDR
Polyxylon is the second and the best‐known cladoxylopsid genus reported from the Devonian of Australia and its primary vascular system and pattern of branch trace emission indicates that the plant had a hierarchized architecture.
