Peer-reviewed journal that published 'Bolide Light Curve Systematics from 75 Recovered Meteorites' (DOI 10.1111/maps.70203).
Researchers dated Oklahoma's Ames crater to 370 million years ago, 97 million years after the Ordovician impacts it was grouped with. That is about 2 million years after the Late Devonian extinction began, though the authors say the impact did not cause it.
Reality
UT Austin geologists dated zircons from Oklahoma's Ames crater to about 370 million years ago, nearly 100 million years younger than believed. That pulls the buried crater out of the Ordovician impact cluster some researchers cited as evidence of a debris ring around the ancient Earth.

UT Austin researchers dated shocked zircons from Oklahoma's Ames crater to about 370 million years ago, nearly 100 million years younger than believed. That takes Ames out of the Ordovician impact cluster behind the idea of a debris ring around Earth.
Reality
An Argentine-led team heated and hammered samples of an iron meteorite at three temperatures and watched the Widmanstatten bands vanish by 850C, which means a plain-looking Bronze Age blade may still be sky iron.

Analysis of 75 videographed meteorite falls puts melting and fragmentation in charge of mass loss. Breakup starts at a fifth of measured meteorite strength, which is where hazard models bend.
