Dama Celiae
''Dama celiae'' is an extinct species of the genus '' Dama'' that inhabited the Iberian Peninsula during the Middle Pleistocene. Description ''Dama celiae'' is primarily known from antler material, as well as scapulas and metatarsals. Unlike modern fallow deer, ''Dama celiae'' has pointed antlers that lack palmation. It has a large, prominent brow (first and lowest) tine which curves upwards, and branches close to the base of the antler. The main beam of the antler lacks branching, and is directed backwards and outwards. Based on the size of the metatarsals ''D. celiae'' may have been larger than living fallow deer, and more comparable in size to ''Dama clactoniana''. Distribution ''Dama celiae'' is known from two sites in Spain, Pedro Jaro I and Orcasitas, which date back to MIS 9 (~300,000 years ago). At these localities it co-occurs with animals like the straight-tusked elephant, aurochs, wild horse, European wild ass, bison, narrow-nosed rhinoceros, wild boar and cave ...

Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...
