Dinosaurs of the Jurassic
| “ | I dreamed of going to the most remote places on this earth to dig for old bones, older than people. Before humans and their stupid ideas. Before hate. Maybe even before love, too. Dinosaurs just existed. No lectures, no books, no language. No world-conquering Europeans and no defeated everybody else. Just those powerful, unrestrained creatures roaming the planet. | „ |

Dinosaurs were a diverse group of animals of the clade Dinosauria that first appeared during the Triassic period. Although the exact origin and timing of the evolution of dinosaurs and their demise is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago.
History[]
Background[]
Dinosaurs became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago. Their dominance continued through the Jurassic and Cretaceous periods and ended when the Cretaceous-Paleogene extinction event led to the extinction of most dinosaur groups 66 million years ago.
Despite the commonly held belief that all the dinosaurs of Mesozoic perished after a cataclysmic extinction event, others believe that a significant portion of dinosaurs in fact survived and went on to live alongside humans until they were eventually driven underground, or left isolated on remote islands yet to be discovered, or even surviving to this day in unexplored regions of the African wilderness or the Amazon Rainforest.
The existence of these creatures is said to be kept secret by clandestine organizations such as the Federal Bureau of Control, which actively conceals the existence and history of these creatures as part of an ongoing effort known as Operation Fossilize. Their aim is to reduce public attention and interest in dinosaurs through the dissemination of disinformation and the recruitment or eliminations of scientists which would expose the existence dinosaurs in the modern day.
Hollow Earth[]
The ongoing efforts to hide the existence of living dinosaurs is partially due to their connection to the thriving biosphere within Hollow Earth, as many of their remaining territories on the surface world can be found near grand entrances into the Hollow Earth. It is absolutely necessary that the locations of these entrances remains hidden from public knowledge.
Most if not all dinosaurs now reside within the subterranean kingdom of Agartha and are more avian than they are reptilian as was originally believed, and they are adorned with pristine and colorfully patterned feathers throughout their entire bodies. These dinosaurs are the Agarthan equivalent of the animals humans have come to know, study, and hunt in the surface world, with dinosaurs filling out practically every niche within the subterranean ecosystem.
Description[]
Dinosaurs are represented on every continent by both their extant avian descendants and their ancient fossil remains. While dinosaurs were ancestrally bipedal, many extinct groups included quadrupedal species, and some were able to shift between these stances. Elaborate display structures such as horns or crests were common to all dinosaur groups, with some extinct groups developing skeletal modifications such as bony armor and spines. Evidence suggests that egg laying and nest building were also additional traits shared by all dinosaurs.
Until the late 20th century, all groups of dinosaurs were believed to be extinct. The fossil record, however, indicates that birds, which are now termed "avian dinosaurs," are the modern descendants of feathered dinosaurs, having evolved from theropod ancestors during the Jurassic Period. A feathered dinosaur is any species of dinosaur possessing feathers. That includes all species of birds, but there is a hypothesis that some non-avian dinosaur lineages, specifically maniraptoriforms and coelurosaurs, also possessed feathers in some shape or form. This theory has been challenged by some research. As such, birds were the only dinosaur lineage to survive the mass extinction event.
While modern-day avian lineages (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs were large-bodied. The largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 meters (59 feet) and came to be known as the largest land animals of all time. Still, the idea that non-avian dinosaurs were uniformly gigantic is a misconception based in part on preservation bias, as large, sturdy bones are more likely to last until they are fossilized. Many dinosaurs were in actuality quite small, with the average height for most genera being about human height.
