Permian

The fastest rate of reptile diversification did not occur at the end-Permian extinction, the team found, but several million years later in the Triassic, when climate change was at its most rapid and global temperatures witheringly hot.

In any case, the new findings show how comprehensive surveys can shed light on methane emissions, which are often poorly understood even in major oil and gas basins like the Permian.

Many think this overhaul happened in a planetwide volcanic event, perhaps on par with the end-Permian extinction that wiped out most species on our Pale Blue Dot.

Based on the reptiles’ size, which was around that of today’s hippos or rhinos, researchers had pegged the Permian Period predators as sluggish beasts that waited to ambush prey.

Occidental, the biggest oil and gas operator in the Permian, will take the carbon dioxide from the air and pump it into old wells to extract more oil.

I am today in Odessa, Texas, here to speak this afternoon at the University of Texas of the Permian Basin.

The Triassic flora is essentially similar to that of the higher Permian strata, though many of the genera are different.

A few words must be said of the fauna of the truly marine Permian beds.

The volcanic outbursts which followed became feebler in the Devonian and Carboniferous periods and ceased with the Permian.

Desert conditions, with confined inland seas, marked the Permian and Triassic periods.
