... peers reminds us that, in any field, there are a few people whose work is so transcendent that, by dint of the examples they set, colleagues seek to emulate not only their methods, but also how they carry themselves in the arena. And so it was with Dave Raup, one of the most...

...Patrick D. Wall; Linda C. Ivany; Bruce H. Wilkinson Abstract Since David Raup's seminal 1976 work, paleontologists have been aware of the relationship between outcrop area and diversity. By incorporating lithologic data derived from Alexander Ronov and coworkers into our own data on areas of mapped...

The common-cause hypothesis is an alternative to the bias hypothesis that invokes either direct or indirect links between the physical...

... of sustainable risk mitigation tactics. We hypothesize that cyanobacteria, and probably other types of algae, produced toxins in the geologic past that caused or contributed to Phanerozoic mass extinctions. To test this hypothesis, we examined the chronologic distribution of cyanobacteria during...

... were also radiochemically determined. These studies, some previously reported, have encompassed the time interval from the Precambrian-Cambrian transition to the late Eocene impact (microspherule) horizons. Our early work strengthened the Alvarez impact hypothesis by finding the Ir (platinum group...

... the studied assemblages for overall comparability. Then we used the Raup & Crick (1979) index of taxonomic similarity coupled with two distinct modes of graphical display to extract and to visualize the patterns of biogeographical relatedness contained in the available data. Of the 94 original RFAs only...

.... In the Western Tarim Basin Cenomanian strata yield Tethyan rudist species. Coiling morphometric analysis using the three-dimensional morphology Raup diagram shows that Requieniidae valves in contact with the substrate are convergent with the basic gastropod shell. More derived strongly coiled, younger...

... therein), it does rise to the level of moderate statistical significance ( p = 0.02) and merits examination. Raup and Sepkoski (1984) identified a 26-Myr periodicity in the extinction of marine families over the past 250 Myr. That paper led to what became known as the “Nemesis hypothesis...

... the hypothesis that short-term variations in rates of genus origination and extinction are artifacts of sampling failures at major unconformities (“Unconformity Bias” hypothesis), the observed evolutionary rates are not correlated with hiatus durations. Moreover, hiatuses that follow the major mass extinctions...
