Animal Armageddon is a 2009 Speculative Documentary series that aired on Animal Planet. Each episode (there are eight in total) focuses on a different extinction event in Earth's history (although there are two episodes about the end of the Cretaceous, because, you know, dinosaurs). The basic plot is that several creatures are shown before the extinction occurs, and that only a few of those shown will survive the extinction event. It also features cutaway scenes of paleontologists talking about the extinctions and apocalyptic quotes from The Bible and other sources.
Anachronism Stew: It's played straight, but only true paleobuffs will notice it.
More noticeable in "The Great Dying", which somehow put the crocodile-like Proterosuchus and the mammal ancestor Thrinaxodon in the Permian, while they are known only from the later Triassic.
What's Staurikosaurus doing at the very end of the Triassic?
Gigantopithecus 74,000 years ago. It went extinct a good 300,000 years ago.
Ape Shall Never Kill Ape: Subverted. Hey, any species will commit cannibalism in the face of extinction.
Apocalypse How: The basic premise of the series. Generally, it's a Class4 event. A future Class1 or Class2 are implied, with regards to humanity.
Crapsack World: Goes hand in hand with the extinction events.
Documentary Of Lies: Usually averted, but it's played straight in the episode about the Triassic-Jurassic extinction. It claims that the Triassic extinction (which, while bad, wasn't going to do much more than wipe out most of the larger animals) nearly wiped out all life on Earth and turned Earth into a new Mars.
Family Unfriendly Death: Quite a number, but the Lystrosaurus and young hadrosaur stand out. In the first case, a gorgonopsian bites down on its neck, spurting blood on the camera. However, the gorgonopsian's jaw structure means that he can only shear off one piece of meat, leaving an enormous pool of blood. What's left of the lystrosaur is scavenged by the protomammal Thrinaxodon. As for the hadrosaur, it is attacked by two Troodon who fail to actually kill it. They are chased away by a Tyrannosaurus rex, who slits the hadrosaur's throat and eats its foot.
Rocks Fall, Everyone Dies: The extinctions all qualify, with the most literal examples ever at the end of the Cretaceous and the hypothetical future.
Rodents of Unusual Size: In "The Next Extinction", after humanity hides underground to survive an asteroid strike, in cities, rats grow to the size of dogs.
Stock Dinosaurs: Not that many, compared to the rest of the cast. Among the great stock dinosaurs, there's Triceratops, Tyrannosaurus, Velociraptor, and the woolly mammoth. Among the semi-stock dinosaurs, there's hadrosaurs. Among the rare stock dinosaurs, there's mosasaurs.
Rule Of Cool: Several less cool and more plausible theories are abandoned in favor of cooler, less likely ones. This is especially noticeable in the Ordovician episode.
The Hunter Becomes The Hunted: Before the Ordovician extinction, the eurypterids are easy prey for the straight nautiloids. During the extinction, the latter becomes smaller, turning the tables.
In the grip of the Great Dying, the wolf-like gorgonopsians, the top predators before the extinction, are easy prey for the aquatic Proterosuchus.
