It's enough to make some people wish all that work had been done when the home was built in the first place. Permian-Triassic extinction). The evidence of such occurrences can be found in the fossils even when a major species group has disappeared from this planet. The shell of the Atlantic calico scallop has about 20 radial ribs, which are sometimes roughened by growth lines. This genus is known in the fossil record from the Cretaceous period to the Quaternary period (age range: from 70.6 to 0.0 million years ago).

The industry has lobbied hard against them. The federal government has made big investments in reducing methane emissions from oil and gas operations, but researchers say you cant reduce what you cant measure, and there are better ways to measure methane. The project is among the first of its kind and advocates hope it will be a model for the future. 1.
