It wasn’t just an asteroid that killed the dinosaurs
Scientists have now obtained enough solid data to confirm that the large extinction of the dinosaurs 65 million years ago was caused not just by the Yucatan asteroid impact but also by the gigantic volcanic event in India called the Deccan Traps.
The researchers said the asteroid strike occurred 66.04 million years ago, plus or minus about 30,000 years. They said eruptions in a region called the Deccan Traps were already underway at a lower intensity but dramatically accelerated after the asteroid strike as if the powerful impact triggered it. The dating method they used found this acceleration began within 50,000 years of the impact, but it could have been in the mere days, months or years afterward. “Within measurement error, they’re simultaneous,” said volcanologist Loÿc Vanderkluysen of Philadelphia’s Drexel University. “The two processes in tandem caused the extinctions,” added Paul Renne, director of the Berkeley Geochronology Center and a University of California, Berkeley geologist, who led the study in the journal Science.
Though many planetary scientists have discounted the Deccan Traps for decades, paleontologists have tended to favor it as a major factor in the extinction. This new study suggests that both were involved, which was the theory held by most of the more reasonable scientists in both fields. While many liked to push one or the other theory in the press, the better scientists considered both a possible factor and have been working to determine this possibility.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
