Unnoticed in the tropics: phylogenomic resolution of the poorly known arachnid order Ricinulei (Arachnida) [PDF]

open access: yesRoyal Society Open Science, 2015
Ricinulei are among the most obscure and cryptic arachnid orders, constituting a micro-diverse group with extreme endemism. The 76 extant species described to date are grouped in three genera: Ricinoides, from tropical Western and Central Africa, and the

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

The West Gondwana margin : Proterozoic to Mesozoic [PDF]

open access: yes, 2008
The longevity and extent of the oceanic southern margin of Gondwana have made it the subject of intense study for more than 70 years. It was one of the cradles of terrane theory and remains a proving ground for theories of supercontinent amalgamation and
