The era before the Dinosaurs was fascinating, with all sorts of prototypes of what would become major animal phyla (well, plant phyla too, but I sadly lack the imagination required to be a paleobotanist). The Mammals descended from a strange group that was dominant at the time, the mammal-like reptiles. They dominated the end of the Paleozoic Era, the "Old Life" before the Dinosaurs of the Mesozoic.
One of the great mysteries of the history of life on Earth is the repeated Mass Extinction events. The disappearance of the Dinosaurs is pinned on an asteroid event, but that extinction is only one of very, very many. In fact, the definition of the end of one era (say, the Permian) and the beginning of another (the Triassic) is defined as a mass extinction event.
Literally, we cannot describe the history of life on this planet without using these mass die-offs as a yardstick. So what caused them all?
A new scientific paper looks to possibly revolutionize the study of Paleontology, and coincidentally sweep "consensus" Climate Science with it. Henrick Svensmark's Cosmic Ray hypothesis is no stranger to long time readers. What's new is a correlation of the fossil record with the well-known astronomical calculations of nearby Supernovae. The correlation is eerie.
Keep your eye on this one. Rather than the rococo climate models, brimming with epicyclic escape clauses, "gridding", "adjusting", and "smoothing", you have a simple hypothesis that maps very, very closely to a data set that stretches back a half billion years.
Read it all, and short the solar and wind power generation companies.
