Titanoboa: Monster Snake (2011)

Meet Titanoboa: She's longer than a bus, eats crocodiles for breakfast and makes the anaconda look like a garter snake. The remains of this 48-foot snake were discovered in a Colombian coal mine. Follow scientists to the mine, into the labs, and into the field while they attempt to reconstruct the life of this enormous reptile that lived in a time just after dinosaurs were wiped from existence.
