Tyrannosaurus Rex Was There to See

It was sixty-six m.y.a The course of all Earth's life did change An orb appeared up in the sky Some would live but most would die Pterosaurs and conifers Magnolias and hadrosaurs Mammals that looked up in fear As the rock came hurtling towards their sphere Hours of terrible violence Years of hardship and of death Tyrannosaurus Rex was there to see The worst day in Earth's history The course of evolution changed irrevocably And cleared the path for our ascendancy Tyrannosaurus Rex was there to see The worst day in Earth's history A sudden flash lit up the sky Another followed, enough to blind The ground began to shake and heave Hot glass rain did burn and cleave Ginkgos and mosasaurs Palm trees and dromaeosaurs The early birds flew up in fear As the rock crashed into their sphere Hours of terrible violence Years of hardship and of death Tyrannosaurus Rex was there to see The worst day in Earth's history The course of evolution changed irrevocably And cleared the path for our ascendancy Tyrannosaurus Rex was there to see The worst day in Earth's history
