"The study, led by researchers at Northwestern University, is the first to measure the calcium isotope composition of fossilized clam and snail shells, which date back to the Cretaceous-Paleogene mass extinction event. The researchers found that -- in the run-up to the extinction event -- the shells' chemistry shifted in response to a surge of carbon in the oceans. This carbon influx was likely due to long-term eruptions from the Deccan Traps, a 200,000-square-mile volcanic province located in modern India. During the years leading up to the asteroid impact, the Deccan Traps spewed massive amounts of carbon dioxide (CO2) into the atmosphere. The concentration of CO2 acidified the oceans, directly affecting the organisms living there. "Our data suggest that the environment was changing before the asteroid impact," said Benjamin Linzmeier, the study's first author. "Those changes appear to correlate with the eruption of the Deccan Traps."…"

"Earth was stressed before dinosaur extinction" My first thought was; 'So….it was seeing a shrink?' There's no way this is what caused the extinction. I've been told for decades that it was the meteor. That is scientific fact! The older I get the more I realize that scientists are people too and make lots of mistakes and have biases. Meteor killed the dinos, Big Bang, Darwinism, etc. just theories. |

"Soo the Dinosaurs caused Global warming?" Yep. Due to their diet, vegetarians tend to release large amounts of methane gas… |
