Join us for the second lecture in the Sharks! Sink your teeth in! Lecture Series, presented by Brett Kent, Principal Lecturer at the University of Maryland. During the Miocene there was a remarkable restructuring of shark communities. Simple tooth morphologies and dentitions that had dominated shark faunas for three hundred million years were rapidly replaced by more complex and diverse dentitions that reflected an expanded range of lifestyles. The factors that triggered this diversification are still only partially understood, but the revolutionary changes that occurred during the Miocene helped establish the pattern for the shark communities we have today.
