Late Hadean Earth before subduction (Heat Pipe Earth). By the author based on NASA images of Io and Earth. Based on NASA images of Earth and Io, with input from Bill Moore and Emily Pope.
How it all lines up so far: Rock dating of Chicxulub impact (left), recently published information on terrestrial and marine extinctions (middle), and recent dates for Deccan lavas. Vertical ‘smear’ of dates depicts 1 sigma uncertainties including from systematic sources from published dates. **the timing of the climate warming in Antarctic waters and extinction events is probably much less certain since it relies in part on uncertain end-Cretaceous magnetostratigraphy. Ar/Ar = Argon/Argon radiometric dates, U-Pb = Uranium-Lead radiometric dates. Boltysh impact shown at 2-5,000 years before Chicxulub based on Jolley et al (2010). Wyoming and Haiti dates for impact traces from Renne et al (2013). Denver data from Clyde et al (2016). Montana data from Sprain et al (2015) Antarctic data from Petersen et al (2016), Deccan data from Renne et al (2015) and Schoene et al (2015).
The “Big Splat” collision of 2 moons to create our present single moon with remnants of the smaller moon forming the mountainous far side. 1 to 3 redrawn from computer simulations by Jutzi & Asphaug 2011, photo from NASA LRO
Depth slices through the oceans showing how dissolved oxygen declines from the surface to middle depths and then rises again in deep water. Constructed from World Ocean Atlas 2013.
Orbital cycles of climate and landscape in Wyoming during the Eocene. Simplified from Smith et al EPSL 2014. Currently it isn’t clear if either A or C coincide with insolation maxima: salt pans may have coincided with the higher evaporation associated with summer insolation maxima, or alternatively enhancement of the monsoon over the western US due to insolation maxima could have led to high lake levels.
