the Permian

Previously, the only dateable layers were from the moment the Permian ended and from a subsequent volcanic event some 14m years later.

This was the end of the Permian period, and of the era of life called the Paleozoic.

This animal spread across the massive, ancient continent of Pangea after the end of the Permian Extinction.

The end of the Permian period, 252m years ago, was marked by the biggest extinction of life known to have happened on Earth.

The typical drowning event of the carbonate platforms at the turn from the Permian to the Triassic formed a typical drowned unconformity.

The two boundaries of the Yili Block have been reworked by the Permian strike-slip faulting.

Dinosaurs appeared after one of the biggest mass extinction events on Earth, the Permian-Triassic extinction about 250 million years ago.

This evidence was used to suggest that at the end of the Permian, 250 million years ago, a comet hit us.

The most recent, the Permian, was thought to have been an impact because of this beautiful structure on the right.

The Permian was curtailed by massive volcanism. But what exactly happened towards the end of the Triassic has been much debated.

Most rock sequences that straddle the end of the Permian are either incomplete or hard to date.

When Grasby and his team analyzed rocks from just before the Permian mass extinction, they noticed unusual microscopic particles.

The Permian seas came to be dominated by bony fishes with fan-shaped fins and thick, heavy scales.

The Permian Shanxi Formation in Yulin Gas Field is a typical low porosity and low permeability lithologic reservoir.

The Permian-Jurassic alluvial-fan, subaqua-fan and delta-fan were widely distributed in the west-north margin of Junggar Basin.

Both the Neoproterozoic and the Permian were times of supercontinent breakup with major landmasses at low latitudes.

That's what some scientists think may have set off the Permian mass extinction event some 250 million years ago.

Was There a Mass Extinction of Land Plants at the Permian -Triassic Boundary ( PTB )?

The Permian-Triassic extinction event about 250 million years ago was the deadliest: More than 90 percent of all species perished.

Each sampling site spanned the mass extinction 252 million years ago at the end of the Permian period.

The pre- Devonian "Gomori Group" shallow metamorphic rock series are mostly redelineated as the Permian strata.

The Permian was curtailed by massive volcanism.

and the Permian natural gases with low content of H2S are mainly from the pyrolysis of organic sulfur source rock.

The Permian period, which ended in the largest mass extinction the Earth has ever known, began about 299 million years ago.

In the slope zone oil is mainly concentrated in the Permian.
