From the Author
Prior to the 1980s, dinosaur extinction was a subject that received only modest attention from the paleontological community. After all, it was believed that dinosaurs, like any other living species, would prosper for some indeterminate period and then fade away. Scientists refer to this process with the an odd description: "racial senescence." This was the observed cycle of life for all fauna and flora in the annals of the Earth.
The pronouncement, around 1980, that the dinosaurs and other animals were the victims of the impact of an extraterrestrial object sent shock waves through the paleontological community in much the same way that the purported "space rock" had done to the Earth's surface some 65 million years ago. The resultant stratification of paleontologists, geologists and other science professionals created two warring camps that are still at odds today. Among those who opposed this theory, proposed by the father-son team of Luis and Walter Alvarez, were well respected members of the scientific hierarchy. The opposition coalesced around an alternate explanation for the extinctions, the Volcanism Theory of Extinction. Today, there is still a split within the scientific community between those that support the impact theory and those that support the volcanism theory. So much attention has been focused on these two theories that any possibility of an alternate theory entering the limelight has been reduced to near zero.
This book describes a new theory of extinction published in 2004 through 2007 and was initially introduced on the Internet in 2004. This theory, written by myself, provides an alternate to the bolide impact and volcanism theories just mentioned. The proposed theory, The Gravity Theory of Mass Extinction (GTME), is applicable to all of the major mass extinctions. However, most of the emphasis will be directed to the Cretaceous-Tertiary (K-T) extinctions. The basic concept, that tectonically driven gravitational changes cause extinction, can best be demonstrated using the K-T extinctions because they have been researched the most.
The Gravity Theory of Mass Extinction attributes the K-T extinctions, and others, to a gradually changing gravitational field at Pangea's surface. This gravitational change is linked to the movement of the Earth's tectonic plates and core elements (i.e., inner and outer iron cores & lower mantle) and is an ongoing process that continues even today. In addition, the extreme gigantism of the dinosaurs and other life forms is attributed to the lowered surface gravitational field during the Mesozoic Era. The causative role of core element movement in the eruption of the massive flood basalt volcanism at the Permian-Triassic boundary (known as the Siberian Traps) and at the Cretaceous-Tertiary boundary (known as the Deccan Traps) are explained by the GTME.
As explained in the Part VI of this book, the most powerful support of this theory comes from a controversy that has arisen in the science of paleomagnetism, the Pangea A vs. Pangea B debate. Paleomagnetists, when reconstructing the position of continents in the distant past, rely on the Geocentric Axial Dipole (GAD) model of the Earth's magnetic field. When they examined the period when Pangea existed, they encountered a stumbling block; they had major problems using GAD to support the widely accepted Pangea A model. An alternate Pangea B model was introduced to supplement the other model although the Pangea B model has been accepted by only a small minority of paleomagnetists. The non-GAD model posited by the GTME is able to resolve the discrepancy between the two models and in doing so proves that the Earth's core elements did move away from their current geocentric position, and therefore, based on the laws of physics, resulted in a change in surface gravitation on Pangea. As Pangea broke apart and its constituent land masses moved latitudinally, surface gravity began to increase. This rate of increase was very high at the end of the Mesozoic Era coinciding with high extinction rates. Chapter 18, The Physics of GTME explains this.
Finally, there is the possibility that the asteroid (or comet), the purported "Dinosaur Killer" that struck Chicxulub, Mexico about 65 mya, had its trajectory distorted by the gravitationally induced effect of the Earth's wobble in the Cretaceous Period, which has been reported in scientific publications, thereby sending it on its deadly rendezvous with planet Earth. Since scientists cannot offer an acceptable cause for the wobble but the GTME can, the following conclusion can be drawn:
The uncanny coincidence of the temporal relationship between the K-T extinctions, the Deccan Traps volcanism and the bolide impact are the result of movement of the Earth's core elements, reacting to movement of the Earth's continental plates. It also follows that since continental configurations have varied widely prior to the Mesozoic Era, other mass extinctions may well have been caused by gravitational changes at the surface of the Earth.
