“Something, as yet unknown, caused sediment to flood the area rapidly...”
I read stuff like this all the time. Thousands of drowned, fossilized dinosaurs found together. etc.
Noah’s flood. They just don’t want to admit it.
That’s exactly what it was.
“Something, as yet unknown, caused sediment to flood the area rapidly”
That something was known. Some people are willfully ignorant.
This flood in ancient Antarctica happened some 199 million years ago in the Triassic period. The largest and most striking evidence of an ancient flood is found in the Washington Scablands where a series of floods from the ice ages in the mid to late Pleistocene (129,000 + years ago and even more recent times) when warming interrupted the Ice Ages. Everywhere in the world there can be found evidence of regional flooding at different time periods but there is no evidence of a global flood. Most of the most spectacular surviving flood evidence dates back to the Ice Ages as a result of melting of massive glaciers.
