SIPHUNCULAR STRUCTURE IN SOME FOSSIL COLEOIDS AND RECENT SPIRULA

Mutvei H.; Donovan D.T. (2006)

In Jurassic Phragmoteuthis huxleyi Donovan (Order Phragmoteuthida) the siphuncular wall shows unique structural and morphological features. The septal neck is short, about one-eighth of chamber length, but the connecting ...

EVOLUTION OF MANTLE STRUCTURE BENEATH THE NORTHWEST PACIFIC: EVIDENCE FROM SEISMIC TOMOGRAPHY AND PALEOGEOGRAPHIC RECONSTRUCTIONS

Miller M.S.; Kennett B.L.N. (2006)

Plate motions and subducting slab morphology are intricately connected, and through the integration of seismicity, tomographic images, and relative plate motions, the evolution of mantle structure can be interpreted. ...
