It could be something as simple as a run away script or learning how to better use E-utilities, for more efficient work such that your work does not impact the ability of other researchers to also use our site.

The trees were sheared off their roots and stripped of their leaves, branches, and bark.

The “forest” of denuded logs floated out over the huge lake.

Could this hypothetical mass extinction be reconstructed correctly from mollusks – hard-shelled animals such as oysters and mussels – preserved in these cores?

When they examined the cores, the results were “somewhat unnerving,” said Michal Kowalewski, Thompson Chair of Invertebrate Paleontology and the study’s principal investigator. Their data appeared to show a mass extinction had occurred, but that idea was false; the species were known to be still living!

“If you apply methods based on the assumption of random fossilization, you get a precise estimate, but it may be wrong by millions of years,” Nawrot said.
