Geosonnet 39



The Kelly Caves, where bushrangers once hid
Were shelter of a venerated kind.
Cro-Magnon ancestors did not forbid
Shelter, and art, in caverns thus confined.
But holes in rock as habitat might date
To early in our planet’s history
The microbes and the cavemen can relate
Archean prelude Pleistocene story
Both sheltered in a mineral cavity.
The upside-down microstromatolites
Cling to the roof, outlaws of gravity
Not methane, autotroph metabolites
   These outlaws hid beneath the algal mats
   Kerogenated troglodytic bats
