##Usage The fossil key is referenced by

fossil_key

An example of a key pair of statements is :

[ { key_pair: 1, statement: "The fossil resembles a modern day seashell", next_statement_pair: 2 },
{ key_pair: 1, statement: "The fossil does not resembles a modern day seashell", next_statement_pair: 8 }]
