Because the Morian Hall of Paleontology is too large to tour in one evening, we are bringing back this popular series that covers the hall section by section with James Washington–now expanded to 6 sessions. All sessions are Wednesday evenings at 6:30 p.m. Journey back 3.5 billion years to the toxic ponds of Precambrian time, where life first appeared–slime mold now preserved as stromatolites. Then on to the glory days of the Cambrian explosion, 540 million years ago when trilobites sprouted horns and elaborate head-dresses. Moving to the Devonian, you will meet an exciting cast of characters. Ferocious fishes encased in thick armor were equipped with self- sharpening fangs strong enough to slice a school bus.
