Bot bacteria

Botulism is a fast acting disease that thrives in rotting flesh. C. botulinum Bacterium appeared in the Episode "The Great Survivors" when a pack of Zunityrannus became infected with the disease when they ate another member of thier kind that was already infected. It was explained that Nothronychus had evolved to survive, as it had almost no chance of catching this disease due to its herbivore state.

This Bacteria still exists in the present day and has been found in dead seabirds on shorelines.
