Question 4 should have been , " What were the ancestors of humans like
 when Tyrannosaurus Rex roamed the Earth ? " Answer; We were doing
 time in purgatory as rats - purgatorius.

I see there was also a Mosesaurus back then in the Maastrichtian. Maybe
 he was a bit like a crocodile faced pied piper of Hamelin leading all the
 dirty rats on a flit out of the chaos of asteroid apocalypse desert to a
promised brave new world. The way some creationists act you would
think they had never left the Cretinaceous period.

Does anyone remember if the Jurassic Park films mentioned what
mammals existed at in the Cretaceous ?
