Here’s what happened in the impact crater the day it did in the dinos

  • A recent drilling project recovered a long core of rock from the Chicxulub impact crater, leading to greater clarity about how the calamity played out—including on that first day.
  • Big enough impact craters actually have a knob of uplifted rock in the center that forms due to the incredible shock forces involved.
  • Higher up in the core, a layer of seafloor sediment seems to record a miraculous return of small critters to the crater within just a couple years.
  • The first layer above the messed-up bedrock that formed the peak ring is made up of 40m of broken pieces of melted rock.
  • The researchers say this material was likely flowing out from the center of the crater for some tens of minutes after the impact.
