Storyboard Text

  • When a rabbit dies you might think it would just rot away, but this is what really happens. 
  • The rotting carcass will be eaten by scavenging animals and eventually sink down underground and be decomposed by bacteria. 
  • After more time, the hard internal skeleton is the only remains of the rabbit left, but over time this will decompose. 
  • Much later, the mud and rock form over the skeleton which is dissolved by ground water, and the area where the carcass of the rabbit would have been, leaves a perfect mold of the rabbit. 
  • Ground water minerals start to fill the skeleton. These minerals form a rock in the mold, that looks exactly like the rabbit. 
  • The finished result is a perfect fossil. The imprint of the rabbit in rock!
