"...Scientists on Wednesday described the surprising fossil discovery showing creatures flourishing in the aftermath of the worldwide die-off at the end of the Permian Period about 252 million years ago that erased roughly 90 percent of species.
Even the asteroid-induced mass extinction 66 million years ago that doomed the dinosaurs did not push life to the brink of annihilation like the Permian one.
The fossils of about 30 different species unearthed in Bear Lake County near the Idaho city of Paris showed a quick and dynamic rebound in a marine ecosystem, illustrating the remarkable resiliency of life..."
"...The Permian die-off occurred 251.9 million years ago. The Idaho ecosystem flourished 1.3 million years later, "quite rapid on a geological scale," according to Brayard.
The mass extinction's cause is a matter of debate.
But many scientists attribute it to colossal volcanic eruptions in northern Siberia..."
"...The Idaho ecosystem, in the earliest stages of the Triassic Period that later produced the first dinosaurs, included some unexpected creatures. There was a type of sponge previously believed to have gone extinct 200 million years earlier, and a squid-like group previously thought not to have originated until 50 million years later.
The researchers found bones from what could be the earliest-known ichthyosaur, a dolphin-like marine reptile group that prospered for 160 million years, or a direct ancestor.
"The Early Triassic is a complex and highly disturbed epoch, but certainly not a devastated one as commonly assumed, and this epoch has not yet yielded up all its secrets," Brayard said..."
[...lots of skippin' 'round..., ya' know- I would be ecstatic if everyone would understand what occurred in 1811, just a couple hundred years ago!]
Can anyone show the evidence to prove these [assumed] dates?
[I call b.s. ...]
[I believe-]They have found fossils from when a comet hit the Hudson bay and emptied out lake Agassiz [10.5kya], which was an inland sea leftover from the Tethys, which had covered a large portion of Pangaea [13kya]... This theory contains the evidence... the geological features, historical accounts, ice cores, sedimentary layers, impactites,... [...and is actually provable, once the evidence finds understanding... -what do you believe?;-]
