Walking with Beasts (2001), focusing on mammal evolution which came after the dinosaurs in the Paleogene, Neogene, and Quaternary Periods.
Chased by Dinosaurs (2002), two specials focusing on two striking dinosaurs, the gigantic Argentinosaurus and the odd Therizinosaurus. This was the first in the Walking with... series to feature a visible presenter (in this case, Nigel Marven).
Prehistoric Planet (2002), a revised version of the Walking With Dinosaurs and Walking With Beasts documentaries, aimed at a younger audience and narrated by Ben Stiller.
Sea Monsters (2003), focusing on dangerous prehistoric marine wildlife, from "the seventh most dangerous sea ever" up to "the first" one. This also featured Nigel Marven.
Walking with Cavemen (2003), focusing on... guess. Also went for the "presenter" format (in this case, Robert Winston).
Walking with Monsters (2005), this time focusing on what came before the dinosaurs. Returned to the presenter-less format favoured by WWD and WWB.
The Complete Guide to Prehistoric Life (2006), a book that producer Tim Haines and consultant Paul Chambers wrote featuring creatures from throughout the series.
Walking With Dinosaurs: The Arena Spectacular (opened in 2007), a touring live arena show featuring life-sized animatronic dinosaurs and performers in costume.
Carnivore Confusion: The "predation is just a fact of life" approach, as most predators are treated as any documentary animals should be treated, not as villains. There are a few exceptions though, mainly in the two spinoffs ending with "Monsters".
Deinosuchus gets only a cameo appearance in Walking with Dinosaurs the TV series, but its badassery is emphasized in the accompanying book, where it's stated that it's even capable of killing a Tyrannosaurus getting too close to the water and later a group of them scares the female Tyrannosaurus away from freshly killed Anatotitan.
Noisy Nature: And HOW! All animals in the whole series make continuously sounds of every kind from roars to bellows, screechs, and so on (a major example of the strong Rule of Cool that characterize this series). The most incredible example is perhaps the early "amphibian" Hynerpeton which makes belch-like sounds without a pause and apparently without any good reason.... despite being a very archaic vertebrate, and thus very unlikely to utter any loud cry.
Another example: giant arthropods like the scorpion Brontoscorpio and the millipede Arthropleuramaking creaking sounds when walking and even when they're moulting their exoskeleton. This kind of sound is heard also during the "Evolution takes over" moments in WWM (just like an horror movie...)
Averted to a greater extent in the original Walking with Dinosaurs, where most of the predators are realistically silent when doing things such as stalking prey, instead of screaming like Godzilla while attacking animals 30 times their size.
Roger Rabbit Effect: Some CGI animals share a scene or two with live-acted ones (including ancient humans), but this is used more greatly for comedic effect in all the various Making of specials.
Rule of Cool: Several examples throughout the series, especially about speculative animal behaviour. Another example is the fact that only the most spectacular animals of each taxonomic group are usually portrayed in almost all the shows of the series, despite they were probably less common in their environments that their smaller relatives (like what happens among modern animals as well). However, we can see many small-sized prehistoric animals too. Still another example is that many animals are more or less oversized in the program: the two most striking examples are the swimming Liopleurodon and the flying Ornithocheirus.
Since the list of examples from this trope is really large, please go here to see them.
Scenery Porn: The shows, by necessity of course, take us to some of the planet's most spectacular-looking, exotic places, and the creators weren't shy in showing them off.
Science Marches On: Many new discoveries have been made after this series, which changed our perception about prehistoric wildlife. These discoveries regard animal behaviour, taxonomy, or other issues. See here for examples.
Stock Dinosaurs: Lots, but a few new additions and subversion as well. For every stock dinosaur used, there's one or more creatures that have never been heard of in mass media before—or, substitution for an appropriate relative. Again, see here for a exhaustive list of examples.
Played straight with the Megalodon from Sea Monsters. Even Nigel starts to sound a bit shaky when the big adult shark approaches his cage, and this is a man who is usually perfectly fine, often even Too Dumb to Live, in the presence of dangerous animals.
Walking with Dinosaurs provides examples of:
Adaptation Expansion: The accompanying book Walking with Dinosaurs: A Natural History contains a lot of additional information about geography of the world dinosaurs lived in, elaborates on some speculative concepts only briefly mentioned in the TV series, and introduces new ones. The book even introduced some creatures that weren't shown in the TV series.
Always a Bigger Fish: Happens on several occasions. Perhaps the most memorable of which was the huge marine reptile Liopleurodon snatching the medium-sized carnivorous dinosaur Eustreptospondylus from the shore. Also an example of another trope since Liopleurodon was probably closer to 4.5-6.5 meters rather than the absurd 25 meters noted in the episode.
In the companion book, a lungfish eats a crayfish, only to be caught by a Coelophysis.
The Coelophysis example is due to the classic (but now mostly discredited) interpretation of what appeared to be remains of young Coelophysis in the ribcage of some adults of the same species, it's not an invention of the show; while the Cynodont one is invented.
Apocalypse Wow: The meteor impact scene in "Death of a Dynasty" is pretty awesome, and much more realistically shown than most other portraits in other documentaries, with the correct sequence of events: first the light, then the earth tremor, then the dust cloud and wind-storms, finally the melted rocks from the sky.
Australian Wildlife: One Walking with Dinosaurs episode centers on Australian wildlife during the Late Cretaceous, the small plant-eating dinosaur Leaellynasaura, the larger plant-eating dinosaur Muttaburrasaurus, the large Temnospondyl Labyrinthodont Koolasuchus, the monotreme mammal Steropodon, an unnamed pterosaur and carnosaur (known only from fragmentary remains), and a weta (a large flightless insect, representatives of which are still alive today).
Bloodier and Gorier: Several scenes of mild or implied violence and death from the TV series were described in rather graphic detail in the accompanying book Walking with Dinosaurs: A Natural History. Compare, for example, the scene of fight between female Tyrannosaurus and the armoured herbivore Ankylosaurus from the TV series with their fight in the book.
Early-Bird Cameo: "Tapejara" navigans was not published until several years after the series aired. The large "Ornithocheirus" (now Tropeognathus) specimen that provided the basis for the (still exaggerated) giant size stated in the show wasn't described until 2012.
New Blood contained the deaths of all the cynodont young (One by being eaten by the Coelophysis, the rest eaten by their own parents in the uncut UK Broadcast/DVD), and cannibalism strikes the Coelophysis as well
"Time of the Titans" obviously with all the Diplodocus youngsters (called "sauropodlets" in the show). So many are alive at the beginning but as the episode goes on most of them die off. In the series only 2 or even 3 survive everything to join a herd, if you read the book only ONE survived
"Cruel Sea" just might be the only part of the series (Except for "Giant of the Skies", which didn't contain much young characters. That focused on old mortality if anything...) where this trope is put into use. As although there may have been implied deaths of the young Opthalmosaurus (a fish-like marine reptile belonging to the ichthyosaur group), the main one manages to avoid death by storms, sharks, and drowning.
Unless you count the very, very graphic instance of Death by Childbirth, which does have a dead little baby Ophthalmosaurus.
"Spirits of the Ice Forest" has young that are mostly implied to have died in the book, mentioning that although many of the Leaellynasaura clan mate and lay eggs usually the only young that will survive is the Dominant Pair's children. (Leaellynasaura was a tiny bipedal herbivorous dinosaur from Cretaceous Australia)
"Death of a Dynasty" has, (besides the Tyrannosaurus young killed by the meteor at the end anyway) the Triceratops-like Torosaurus young killed by dromaeosaurids (commonly known as "raptors") and an implied death of a picked on Tyrannosaurus. And if it counts: the small mammal Didelphodon eating the eggs.
The Peteinosaurus and Plateosaurus examples may be justified, since they lived at the time of Pangaea. They could easily have migrated from Europe into North America or vice versa.
Mood Whiplash: In the arena show, the mother Tyrannosaurus scares away the Torosaurus and Ankylosaurus harrassing her baby. The mother and her baby then share a cute little moment where she goes around roaring at the audience and he tries to mimic her, with underwhelming results. They nuzzle a bit, and then the comet hits.
Nobody Poops: Averted in "Time of the Titans". Not only do they show a full view of a Diplodocus defecating twice, but they also show the pile of shit and the dung beetles crawling all over it.
Palette Swap: Similar looking animals (like Utahraptor and Dromaeosaurus, various ornithopods) were just these. Certain animals (like large theropods and ornithopods) only got new heads. You can tell, because many creatures have the exact same folds and blood vessels on their skin. Then, there is Plesiopleurodon, which is just Stock Footage of Liopleurodon from the previous episode, only tinted lighter.
Papa Wolf: The male cynodont. Until the Coelophysis discover the burrow and he decides that the young aren't worth defending anymore, at least...
Prehistoric Monster: Gorgeously averted, perhaps except only for Liopleurodon, which still behaves like a real animal, but is presented in a sinister light. The portrait of T. rex is of particular note: they appear more good mothers and playful youngsters than scary killers.
Real Is Brown: Averted, although most other artwork makes dinosaurs with boring, green/grey colours, here they are often brightly coloured with stripes, spots and patterns, like reptiles and birds are today.
Red Herring: Eustreptospondylus being shown during the opening narration of Cruel Sea, with Kenneth Branagh talking about "the most fearsome predator of the Jurassic" that "is watching his prey". Only a few moments later it becomes obvious that this narration wasn't about Eustreptospondylus, but instead about Liopleurodon
This is ruined in Italian dub: here the narrator says "Eustreptospondylus, the most fearsome predator of the Jurassic..." (sigh)
Apparently some paleontologists strongly criticized the scene from the first episode of Walking with Dinosaurs where Postosuchus was shown urinating in a way more similar to that of mammals than that of reptiles and birds, despite it was an ancient relative of both crocs and dinos - so strongly in fact, that one of the series' scientific consultants, Prof. Michael Benton, decided to address their criticism. The relevant bit: "Another category of WWD-haters, the fact checkers, began compiling lists of errors in the first week. These were gleefully circulated on the e-mail lists. For example, in the first programme, Postosuchus urinates copiously. There is no doubt that it does so in the programme, and this was a moment that my children relished. However, of course, birds and crocodiles, the closest living relatives of the dinosaurs, do not urinate; they shed their waste chemicals as more solid uric acid. Equally, though, we canít prove that Postosuchus did not urinate like this: copious urination is the primitive state for tetrapods (seen in fishes, amphibians, turtles, and mammals), and it might have been retained by some basal archosaurs."
This combines the twin arts of whining and digging oneself deeper into a hole. His argument is similar to "well. we can't prove for certain that T. rex didn't breathe fire, so there's nothing wrong with having it do so in our documentary." Also note that excreting uric acid uses less water than excreting urea, which gives doing so a selective advantage in dry environments like deserts. Guess where New Blood is set? That's right, the biome least conducive to a urea-excreting reptile.
If the animal is another predator, another way is to have it prey on or scare away another stereotypically dangerous predator such as a theropod or shark. Most famously done with Liopleurodon; and then the several Threatening Shark examples of course (see above).
Big Damn Heroes: A Smilodon cub is chased by a pair of Phorushracos at the beginning of the Saber Tooth episode, but then Half-Tooth appears out of nowhere and scares the Terror Birds away just when they're about to eat the cub.
Scavengers Are Mean: One example in Beasts: The pig-relatives entelodonts are portrayed as scary as possible, with enormously wide mouths, always-screeching behaviour, and described as "the Hogs from Hell" which do nothing else but bullying other animals; while true WWB predators like Smilodon tend to receive a more neutral portrait.
Sexy Discretion Shot: The scene of the mating Australopithecus even had to be censored with a huge blur for the American release (but strangely did't cut it entirely, like in Australia), because it looked exactly like the way humans do it.
Spared by the Adaptation: The second Smilodon brother is fatally wounded in the original episode, but in the corresponding chapter of the book, he just runs away.
The Worf Effect: In Land of Giants, a mob of entelodonts have this on a lone Hyaenodon, but a lone entelodont is then scared away by the indricothere calf. Meanwhile in the book, it's a pair of Hyaenodon that drive off a single entelodont.
In the episode Saber Tooth, a Megatherium shatters the dominance of the antagonistic Smilodon brothers by killing one of them, and later on Half-Tooth (The Hero) completes the effect by killing the remaining brother.
Averted in 'Mammoth Journey', where the humans (neanderthals and modern humans) are treated like any other predator and the mammoths are the clear protagonists.
Just to be clear how much this is averted, in 'Mammoth Journey' a mammoth bull casually finds two cave lions feeding on a dead man. We don't even see how he died, only the mammoth scaring the lions away because they are on his path.
Palette Swap: Thankfully averted by the iguanodonts and the Tarbosaurus, as these received new animation models (or at least new details) instead of being straight reuses of almost identical models from the original series.
Anachronism Stew: T. rex appearing in a Cameo role 75 million years ago, whereas the oldest known rex dates from "only" about 68 million years ago. And it's clearly confirmed to be a real T. rex in the book, not one of its ancestors.note Daspletosaurus would have been more appropriate.
Death World: While nearly all the seas could counts, the Creataceous Western Interior Seaway, which is actually called Hell's Aquarium to signify its dangers, particularly stands out.
More of a subversion, none of the animals (with the possible exception of the mosasaurs) behave in a way that is necessarily monstrous, they're just shown in a more sinister light than in previous documentaries.
Schmuck Bait: Nigel repeatedly states that there's no way he would go into "Hell's Aquarium" - but decides to dive in anyway to ride a giant sea turtle.
Darker and Edgier: Has a scarier edge to the fight for survival than Dinosaurs and Beasts.
Death by Sex: The male Hynerpeton gets eaten by a Hyneria right after it mates. In an interesting subversion, this only happens because it failed to mate the previous night, so in a way, it's a case of "death by belated sex".
Carboniferous Period:Proterogyrinus was likely extinct by the time chronicled in this segment.
Early Permian Period:Edaphosaurus is unknown from Europe, including the Bromacker Quarry.
Late Permian Period:Rhinesuchus and Gorgonops are unknown from Russia and probably were restricted to the Southern hemisphere.
Early Triassic Period:Euchambersia, Proterosuchus, and Euparkeria are all unknown from Antarctica.
Prehistoric Monster: It's even titled Walking With Monsters! Predators here are represented in a scarier way than the original Dinosaurs and Beasts.
The idea is kind of that this is before the Earth had a ruling class, so different groups of animals were ferociously and graphically battling it out to be the dominant species. Things become more relaxed by the Mesozoic and Cenozoic, as seen in WWD and WWB.
Late Permian Period:Gorgonops, Diictodon, Rhinesuchus, Scutosaurus
Early Triassic Period:Lystrosaurus, Euparkeria, Proterosuchus, Euchambersia
Somewhere, a Palaeontologist Is Crying: Walking With Monsters plays this trope straight more than any other presenter-less series. Evolution is described here as a war between predators and preys and many predators (giant arthropods and the giant fish Hyneria for example) are portrayed as a sort of Hollywoodian Big Bads that do nothing else but menacing the protagonist species (portrayed as a sort of Hollywoodian hero who fights enemies several times stronger). It's worth noting that big primitive arthropods like scorpions and spiders weren't an obstacle for vertebrate evolution: they instead did help our ancestors in an indirect way, preying upon the less adapted of them and thus selecting actively their best-adapted traits. One can say that they "guided" actively their evolution and perhaps even contributed to make primitive fish becoming amphibians and finally Amniotes (the group including "reptiles", birds and mammals). In a sense, they may better be considered our friends rather than our enemies. This argument is more widely discussed in Prehistoric Life.
