A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes).

The chimpanzee–human divergence likely took place during around 10 to 7 million years ago. [1] The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.

Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
Sexual dimorphism in dinosaurs refers to the different physical characteristics of male and female dinosaurs of the same species. This means that the male and female dinosaurs of a species may differ in size, color, shape, or they may even look like a completely different species altogether, such as in the case of the anglerfish .
This list of nicknamed dinosaur fossils is a list of fossil non-avian dinosaur specimens given informal names or nicknames, in addition to their institutional catalogue numbers. It excludes informal appellations that are purely descriptive (e.g., "the Fighting Dinosaurs", "the Trachodon Mummy").
Walking with Cavemen follows the previous series Walking with Dinosaurs (1999) and Walking with Beasts (2001) in showcasing prehistoric life in a nature documentary style. . Beginning in Ethiopia 3.2 million years ago, Walking with Cavemen follows the story of human evolution through exploring key developments on the path from Australopithecus afarensis to modern hu
In 1913, Forster-Cooper named a new genus and species, Thaumastotherium ("wonderful beast") osborni, based on larger fossils from the same excavations (some of which he had earlier suggested to belong to male P. bugtiense), but he renamed the genus Baluchitherium later that year because the former name was preoccupied, as it had already been ...
