  4. Earth's mountains disappeared for a billion years, and then life stopped evolving A dead supercontinent may be to blame By Brandon Specktor, Live Science Tang, M., Chu, X., Hao, J. and Shen, B., 2021. Orogenic quiescence in Earth’s middle age. Science, 371(6530), pp.728-731. Yorus, Paul H.
  5. Sinopaleus

    Grypania spiralis

    Generally accepted to be one of the earliest eukaryotes, these spiral ribbons are also the oldest macroscopic body fossils known to date. The Negaunee Fm. has been dated to 2.11 billion years old, but new studies suggest the unit is 1.87 billion years old. These ribbons are most simply referred to as a form of archaic alga, and existed when increasing oxygen levels caused global rusting of the oceans, also resulting in the extinction of other lifeforms unable to adapt to the then-toxic levels of oxygen.
