Ephemeral crustal thickening at a triple junction: the Mendocino crustal conveyor

Article Abstract:

The interaction of the Mendocino triple junction and the Gorda slab has resulted into the temporary thickening of the North American continental crust. A model, adhering to time-dependent, finite-element and thermal-mechanical elements, has been constructed to study the ultimate consequences of triple-junction migration on large-scale plate tectonics. It is expected that flexural downwarps could develop as a result of this northward migration.

Evolution of fish -shaped reptiles (Reptilia: Ichthyopterygia) in their physical environments and constraints

Article Abstract:

Ichthyosaurs are a group of Mesozoic marine reptiles that evolve fish-shaped body outlines. These reptiles are unique in many ways including the possession of enormous eyeballs that sometimes exceed 25 cm and an enlarged manus with sometimes up to 20 bones in a single digit or 10 digits per manus.
