YouTube Description
as posted by the channelIt took a decade for scientists to accept that an impact caused the dinosaur extinction...until the crater proved it.
At the Younger Dryas boundary (~12,900 years ago), the same markers appear: iridium, platinum, and nanodiamonds. Those nanodiamonds are otherwise known only from the dinosaur extinction layer.
When the signatures match, the question isn’t if something happened... it’s what we’re willing to acknowledge.
