The Cretaceous breakup of Gondwana strongly modified the global distribution of shallow tropical seas reshaping the geographic configuration of marine basins. However, the links between tropical reef availability, plate tectonic processes and marine biodiversity distribution patterns are still unknown. Here, we show that a spatial diversification model constrained by absolute plate motions for ...

Crittenden Springs in northeastern Nevada yields M. gracilitatis Zone ammonoids renowned for the finely detailed, exquisite preservation of the test, which sometimes even displays relict color patterns. Evidence reveals most of the fossiliferous Lower Triassic beds in the Crittenden Springs area are overturned and this conclusion places the Meekoceras gracilitatis Zone portion of the section an...

A parametric wave spectrum resembling procedure is applied to detect the sea state parameters, namely peak period and significant height, based on measurement analysis of heave pitch motions a vessel in seaway, recorded by smartphone located onboard ship. The system makes it possible determine acceleration spectra reference ship encounter frequency domain and, subsequently, absolute once motion...
