The days when gruff, thickbrowed club-wielding cavemen and sexy cavewomen in body-baring fur teddies roamed the earth alongside dinosaurs. Most humans were of low intelligence and
communicated primarily in grunts, but this didn't stop them from inventing a sophisticated system of Bamboo Technology, most of which incorporated rocks, sinews, and small anthropomorphic dinosaurs who really didn't seem to mind the fact that they'd been locked under a counter and forced to serve as a primitive garbage disposal for the vast majority of their waking lives. ("It's a living", after all...)
Real "cavemen" were quite different — although of course, it entirely depends what point in prehistory you're focusing on. They (at least in the last 100,000 years or so) were as intelligent as modern humans and had complex language. They used bows, spears, slings, and knives as well as clubs. They lived in tents or huts, sometimes structures built of mammoth bones, and maybe the mouths of caves but never deep inside. Most prejudices about cavemen were originally applied to Australian Aborigines, pygmies, Native Americans, and black people.
And there werenodinosaurs living alongside them, no matter what Jack Chick wants you to think (well, except for the birds).
If any genuine attempt is made to explore what prehistoric cultures might have been like, it could be considered to fall into the category of Xenofiction.
See Prehistoria for a Video Game level or setting set here.
The 1950's comic book Tor drawn by Joe Kubert. A foreword in the modern collected edition apologetically says "Although it was already known to anyone who cared that men and dinosaurs had never dwelt on Earth at the same time...."
The GEICO "caveman commercials" feature stereotypical-looking thick-browed Neanderthals with Genius Bruiser personalities from this era, somehow still living in modern times and acting like an oppressed minority.
As does Cavemen, the short-lived TV series based on the Neanderthals from the commercials.
The lesser known Spiritual SuccessorWhen Dinosaurs Ruled The Earth (1970) is also a good example.
Yor: The Hunter from the Future starts this way, complete with dinosaurs, giant lizards, women in furskin bikinis and barbarian heroes, only for it to be subverted with it being in fact a future world, not a prehistoric one.
Quest for Fire, one of the more accurate depictions of the Stone Age. In a piece of truly inspired casting, Ron Perlman was one of the cavemen.
Ringo Starr's Caveman, an open parody/comedy take on the genre, is set in "One Zillion years ago". October 9.
Replace dinosaurs with pyramid-building Egyptians and you get 10,000 BC, which no one with even the slightest interest in actual prehistory, paleontology, or archaeology should bother even trying to watch. It's implied the leaders are in fact Atlanteans. It's stupid, but at least it isn't restrained. And in fairness, the movie was an obvious homage to One Million Years BC, and adopts the same "eh whatever" attitude towards accuracy.
Year One features Hunter Michael Cera and Gatherer Jack Black as cavemen gatecrashing Biblical-narrative events. The problem is that while the story of Cain and Abel could be set at One Million BC, early Israelites like Abraham are much less so. And then there's those Romans showing up. Anachronism Stew all around!
Earth's Children is a fairly well-researched attempt to construct realistic Ice Age cultures and involves clashes between Homo sapiens and Neanderthals. Science has marched on concerning some of the material Jean Auel used, and Ayla and Jondalar's technological inventions can only be believed as allegories for the inventions of multiple generations of Real Life people, but for the most part these books are quite believable and realistic. Their biggest problem is the Anachronism Stew of Homo sapiens material culture, mixing multiple Paleolithic eras together, and arguably the near total lack of Values Dissonance in the prehistoric Homo sapiens cultures.
The Ram series, a Finnish children's book series by Maijaliisa Dieckmann, is about a girl called Ram living in prehistoric times, supposedly in what is now Finland. Her parents die on a long hunting trip and she is left to take care of her little brother alone with the grudging help of the neighbours who have too many children and elders to feed to care for two orphans. For emotional support, she turns to her dead grandmother who she believes is the family's spirit protector. The books also deal with discrimination as Ram's family is originally from another clan and they are thought of as outsiders in the village. In a later book she leaves the village with her brother to find her parents' original clan and rejoin her distant relatives. The author is a well-known and respected historical novelist so the depiction of the era is very accurate and life-like.
The Stephen Baxter book Stone Spring which is set at the end of the most recent glaciation. The prehistoric inhabitants of the land that once connected Britain to the rest of Europe embark on an ambitious mud wall building to hold off the rising tide.
"Sabre Tooth" and "Mammoth Journey", the last two episodes of Walking With Beasts, were set during the Pleistocene, in South America and Europe, respectively. And yeah, it was pretty darned accurate.
The finale of the re-imagined Battlestar Galactica, which occurs 150,000 years before present day, veers into this. The proto-humans the main characters observe, however, seem to avert the traditional cavemen stereotypes with Baltar commenting that they use tools and have a primitive society but is unsure if they have a comprehensive language. It is an educated guess that this also becomes the way of life of the Colonials thanks to Lee Adama's decision to get rid of all technology and live a primitive, simple life.
Played absolutely straight in the "search for the Quantasaurus Rex" arc of Power Rangers Time Force, where Wes and Eric see Triceratops, Stegosaurus and get chased by an irate Tyrannosaurus, before Wes finds fairly advanced wall-paintings of the aforementioned Quantasaurus Rex.
Another comic strip example: Johnny Hart's B.C., which also seems to be taking place in a bizarre Alternate Universe filled with modern humor (if you can call it that) and Fundamentalist Christianity. Johnny Hart is a (young-earth) creationist, so he may actually believe dinosaurs roamed the earth with cavemen. The low quality of the later Hart years was more tragic given that it was a pretty good comic strip before he saw the light and began filling it with Author Filibusters expounding his theology.
Then there's the theory that the strip isn't really set in the prehistoric era at all, but rather a post-apocalyptic future.
Many thought that the fundamentalism didn't really work in a strip named for the abbreviation of "Before Christ". Word of God had it that the strip was actually named after a college in Hart's hometown, but whether this was originally the case or just a Retcon dreamed up after Hart's conversion is unknown.
With Hart's death and the strip passing into new hands, the overt Christianity references have been tossed back overboard.
The GURPS RPG supplement Lands Out Of Time introduces the "World of Banded Night" - which is this trope. It includes dinosaurs, cavemen, ape-men, even lizard-men and the ruins of an ultra-tech civilization.
The world of Jund in the Shards of Alara expansion for Magic: The Gathering is pretty clearly based on this trope, though they get away with it by being pure fantasy. Actual dragons replace the dinosaurs, brutal reptilian humanoids lord it over tribes of primitive humans and goblins, and the land itself is scarred by volcanic rifts where it isn't covered in chokingly dense jungle or festering tar pits.
The Ice Age movies are the Talking Animal version. It manages to sneak in dinosaurs inside blocks of ice. Somehow the onset of the ice age and its ending were only a sequel's width apart.The third movie has living dinosaurs, but they at least have the decency to live in a Lost World. And the fourth will add the continental drift! Geology means nothing to Blue Sky Studios.
Histeria! made this (and the time before it) the subject of the episode "The Dawn of Time".
The Super Mario World cartoon ran with the fact that the game was set in a place called Dinosaur Land and had the show set in the Stone Age, populating the place with lots of cavemen, including Oogtar the Not-Toad.
Looney Tunes did three shorts of this type: "Prehistoric Porky", which takes place in One Billion, Trillion BC and shows Cavepig Porky's near-fatal chase with a saber-tooth tiger, "Daffy and the Dinosaur", which takes place "millions and billions and trillions of years ago" and shows a caveman hunting Daffy Duck, and "Pre-Hysterical Hare", where Bugs Bunny finds a caveman's documentary about life in 10,000 B. C. E.
In one episode of The Fairly OddParents, Timmy wishes there was no such thing as technology, so Cosmo and Wanda turn the clock back to the stone age.
The Phineas and Ferb episode "Tri-Stone Area", set in 27, 000 B.C., where "Phineagrunk And Gurb" invent the wheel.
In the DuckTales episode "Marking Time", Scrooge literally travels back to 1 million BC to find a land in which caveducks coexisted with dinosaurs. And yet, this is something of an aversion; after all, dinosaurs did coexist with ancestral ducks. However, it does therefore imply that the Duck Universe takes place in the Paleocene, which would make sense, since that was a time dominated by six-foot birds.
