Jurassic tracks and HS2: a twenty‐first century journey
The biggest UK railway construction site since the nineteenth century has exposed a near‐complete time slice through the entire Jurassic succession of central England. This is yielding a wealth of stratigraphical, palaeobiological and palaeoenvironmental data that is otherwise generally poorly exposed at the present day.

Summary A key feature of extant conifer forests is the high percentage of seeds that germinate and establish on dead wood; in some forests, this can exceed 90%. This deadwood can act as an ideal nursery for young tree species, leading to this type of seedbed being termed ‘nurse logs’.

The Jurassic of Denmark and Greenland: The Upper Jurassic of Europe: its subdivision and correlation [PDF]
In the last 40 years, the stratigraphy of the Upper Jurassic of Europe has received much attention and considerable revision; much of the impetus behind this endeavour has stemmed from the work of the International Subcommission on Jurassic Stratigraphy.

New Early Jurassic thylacocephalan assemblage from the Western Carpathians in Slovakia [PDF]
Thylacocephalans (Euarthropoda: Pancrustacea) are extinct marine pancrustaceans characterised by a folded shield, with fossils known from the Upper Ordovician to the Upper Cretaceous, reaching a diversity peak in the Triassic.

Abstract Continental breakup involves multiple extension styles; each linked to unique structural and sedimentary processes. High‐angle, low‐angle, listric and antilistric normal faults develop at different stages and positions during rifting. The Bay of Biscay and its margins, a prototypical example of magma‐poor rifted margins during Jurassic ...

Detrital events within pelagic deposits of the Umbria-Marche basin (Northern Apennines, Italy). Further evidence of Early Cretaceous tectonics [PDF]
Re-sedimented deposits characterize different stratigraphical intervals in the pelagic successions of the Umbria-Marche-Sabina Domain (Central and Northern Apennines, Italy).

Abstract Inception of obduction is a rare phenomenon in the Wilson cycle and requires specific prerequisites to transfer relatively high‐density oceanic lithosphere over the less‐dense continental lithosphere. The world's famous Semail ophiolite belt developed during the Late Cretaceous, when Neo‐Tethyan oceanic lithosphere obducted onto the rifted ...

A review of the fossil record of turtles of the clade Thalassochelydia [PDF]
The Late Jurassic (Oxfordian to Tithonian) fossil record of Europe and South America has yielded a particularly rich assemblage of aquatic pan-cryptodiran turtles that are herein tentatively hypothesized to form a monophyletic group named ...

A Paleotectonic Atlas of the African Plate: Permian to Recent
ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...
