| 3:10 | Permian limestones mark boundary of Permian extinction | 4:00 | Douglas Erwin (National Museum of Natural History, Smithsonian Institution), Yugan Jin: Early Triassic paper-thin bivalves (NOT crinoids as shown in the caption) indicate low oxygen (Zhejiang Province, southern China) | 5:00 | 2-mile thick lava beneath oil fields due to Permian volcanic eruptions (west Siberia) |
| 10:20 | Supercontinent Pangea formed 300 MYA, surrounded by deep ocean trench, causing lava dome to rise | 12:00 | Drilling for methane hydrate frozen in deep ocean (off Japan) | 13:30 | carbon 12 released by melting of methane hydrate at Permian boundary indicates global warming and decreased oxygen (Zhejiang Province, southern China) |
| 17:40 | Berthierine mineral indicates low oxygen in early Triassic (10%) from death of plants and methane reacting with oxygen (Transantarctic Mountain Range, Antarctica) | 19:50 | Cynodont managed to survive | 20:40 | Plans and dinosaurs returned |
| 20:50 | Apatosaurus | 20:55 | Allosaurus | 23:00 | Dinosaurs had air sac respiratory system like birds for efficient breathing in low oxygen |
| 29:20 | Thrinaxodon ribcage covered only its chest, can support a diaphram for breathing, and twist for nursing | 32:00 | Mammal mother and offspring fossil side by side indicated care of young (South Africa) | 32:40 | Mammal fossil with placenta 125 MYA (China) |
| 34:50 | Asteroid strike wiped out dinosaurs 65 MYA | 37:10 | Carpolestes had opposable thumb like primates 56 MYA | 38:20 | Diatryma was a ferocious predator, almost 2 meters tall (Europe and Americas, Africa, Antarctica, but not Asia) |
| 44:10 | Hyaenodontids predatory mammals had 3 sets of teeth and were fast runners; evolved in Asia | 46:00 | After ice melted, mammals moved across land bridge to North America; Hyaenodontids hunted down Diatryma |
