Dinosaurs were not killed off by an asteroid

Posted by Henry Bauer on 2020/10/03

Among the several mainstream scientific theories that happen to be unproven or simply wrong [1] is the belief,  accepted by the media’s conventional wisdom (and thereby by society at large), that the dinosaurs  became extinct as a result of environmental changes caused by an asteroid that crashed into the Atlantic near the eastern coast of Mexico (the Chicxulub crater, which lies mostly under water).

To the contrary,  many geologists and paleontologists have always argued that the extinction was not  as sudden as the asteroid scenario suggests, and that in fact it was caused by the environmental consequences of long-continuing and vast volcanic eruptions in what are known as the Deccan Traps in India [2].

A comprehensive but concise and well-documented discussion of these possibilities, with mention of a third theory, is a given by Christian Smoot  in a letter to the NCGT Journal, volume 7 #3.

NCGT Stands for New Concepts in Global Tectonics, an organization founded by professional geologists and others who recognized geological phenomena that seem not to be explainable by the mainstream theory of moving geological plates, i.e. global tectonics, the scientific designation  for what popular discourse calls continental drift.

The journal is publicly available. It should be of considerable interest  to people who realize  that what the public hears from mainstream science is not always the last, absolutely true word.
