The cave bear (Ursus spelaeus) is a prehistoric species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum. Both the word cave and the scientific name spelaeus are used because fossils of this species were mostly found in caves .
Cave lion skull exhibited in the Muséum de Toulouse, France. In 1774, Zoolithenhöhle cave near the village of Burggaillenreuth in Bavaria, southern Germany was brought to scientific attention by Johan Friedrich Esper, who realised that the bones of extinct animals were present in the cave. [5]
Arctodus is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,800 years ago). There are two recognized species: the lesser short-faced bear (Arctodus pristinus) and the giant short-faced bear (Arctodus simus).

The extinct cave bear (Ursus spelaeus) was also heavier than many recent bears. Largest males weighed as much as 1,000 kg (2,200 lb). [149] Ailuropoda baconi from the Pleistocene was larger than the modern giant panda (Ailuropoda melanoleuca). [150]
The Gamssulzen Cave bear survived U. spelaeus for about 1000 to 2000 years, locally replacing this species, but also became extinct about 30,000 years ago, just prior to the Last Glacial Maximum. The reasons for their extinction are still being discussed, with climate change and human hunting suggested as possible reasons. [8] [10]
It has been shown that the prevailing climate at the time of extinction (40,000–50,000 BP) was similar to that of today, and that the extinct animals were strongly adapted to an arid climate. The evidence indicates that all of the extinctions took place in the same short time period, which was the time when humans entered the landscape.
A single cloned individual was born on July 30, 2003, but died several minutes later, [76] making this the first case of biological taxon de-extinction and a taxon becoming extinct twice. In 2014, Spanish ibexes from the Guadarrama Mountains were released in the French Pyrenees as proxy for the Pyrenean ibex.
