It took less than 30,000 years and maybe only thousands, to kill more than 90% of sea creatures and most land species, according to the most precise study ever published about the mass extinction marking the end of the Permian Period.
Earth's greatest mass extinction, also known as the "Great Dying," occurred about 252 million years ago. By some estimates, over 90% of sea creatures and most land-dwelling reptiles disappeared. Even usually resilient plants and insects suffered near annihilation...
Scientists from China, the USA and Canada combined new high-resolution radiometric dating of seven closely spaced layers of volcanic material from South China's Penglaitan section with detailed biostratigraphy and geochemical analyses. Results show the duration of the end-Permian mass extinction to be about 31 thousand years, essentially instantaneous by geological standards...
SHEN and his colleagues documented a rich Late Permian biota at Penglaitan, with at least 10 major marine fossil groups, including brachiopods, ammonoids, sponges, corals, conodonts, foraminifera, bryozoans, bivalves, and trilobites. Twenty-nine of the 66 Permian species identified in the section disappeared within or at the top of a single bed of volcanic ash-rich sandstone (Bed 141). Moreover, there is no "survival interval" of Permian taxa extending into the Early Triassic. This highly diverse marine ecosystem suddenly disappeared during the time of deposition of Bed 141...
High-resolution paleotemperature measurements across the mass extinction interval suggest a substantial warming of up to 10 degrees Celsius immediately after the mass extinction event.

The Deccan Traps may have caused massive climatic change also through abnormal v olcanic action.
It wasn't just rainfall that flooded the earth.
“...astrobleme...”
Darn. I thought I had a new word to call liberals...but then I looked it up and found out it’s just a geological term.
3,000-30,000 years may be a geological instant but it is a VERY long time biologically. A cataclysmic event like an asteroid strike could cause extinction in several months due to starvation or in days due to asphyxiation or widespread environmental changes.
“Are you skeptical of continental drift, general relativity, and molecular genetics as well?”
Don’t forget penicillin.
The methods they've got to use can't squeeze down to that point, and since the Deccan Traps' oldest dates are millions of years after the P-T extinctiion, they can't possibly be the culprit.
It wouldn't, and didn't. Didn't kill the sloths, koala bears, pandas, orangutans, etc, and the dinos were dead more than 60 million years before the date given for Noah. Oh, and with modern power tools it took over 300 man-years of labor to build the Ark replicas.
