Geosonnet 70
Geosonnet 70
Amusement parks of resurrected beasts
Traditionally lie on offshore isles.
But dinosaurs, volcanoes now extinct
Might be preserved in sediment’ry piles.
Eroding mountains shed their clastics west
Until they rest in Eromanga seas.
The sand where Muttaburrasauri rest
Has zircons from unknown localities.
Cretaceous rifting pushed the arc offshore.
This thinning crust by newborn ocean drowned.
The Norfolk Ridge and Lord Howe Rise may store
Jurassic arcs where source rocks may be found.
The dinosaurs and arcs are gone today
But just like life, the zircon finds a way.
