Scenarios about 'dinosaurs'
The diverse group of reptiles that dominated Earth's terrestrial ecosystems for approximately 165 million years during the Mesozoic Era. Dinosaurs ranged from chicken-sized creatures to massive sauropods, evolving into thousands of species before most were wiped out in the Cretaceous-Paleogene extinction event about 66 million years ago. In alternate history scenarios, their continued existence or different evolutionary paths often explores how human civilization might have developed alongside these creatures.
What If The Cretaceous-Paleogene Extinction Never Occurred?
Exploring the alternate timeline where the asteroid impact 66 million years ago missed Earth, allowing dinosaurs and other Mesozoic species to continue evolving alongside mammals in a dramatically different world.
What If The Dinosaurs Never Went Extinct?
Exploring the alternate timeline where the Cretaceous-Paleogene extinction event never occurred, allowing dinosaurs to continue evolving alongside mammals for the past 66 million years.
What If The Permian-Triassic Extinction Never Happened?
Exploring the alternate timeline where Earth's most devastating mass extinction event never occurred, potentially altering the entire trajectory of evolution and preventing the rise of dinosaurs and mammals as we know them.
What If The Dinosaurs Never Went Extinct?
Exploring how Earth's evolutionary history and potentially human existence would have unfolded if the catastrophic asteroid impact 66 million years ago had never occurred.
