Cave Bear

A cave bear is a very large bear that shaped the sister lineage of surviving brown bears and polar bears. It is either of two extinct bear species (Ursus spelaeus) and U. deningeri, remarkable for its habit of inhabiting caves. Pleistocene cave deposits in Europe are where its remains are often found preserved. An isotopic assessment of fossil collagen from the bones assembled in three Romanian caves show that the cavern bear (Ursus spelaeus), a terminated type of bear that lived 300,000-25,000 years earlier in Europe, the Mediterranean, and Asia, was exclusively herbivorous.

Besides characteristics, they have a specific IUCN ranking, scientific classification,  taxonomy, habitat, Feeding pattern, Ecology, and a life cycle, which we will discuss on this page along with the amazing cave bear animal facts.

Cave Bear Etymology

The European Cave Bear existed during two different ice ages and is one of the well-known mammals of the Ice Age. 

It is believed to have evolved from the Etruscan Bear (presumably Ursus deningeri) and lived between 5.3 million years ago to about 10,000 years ago. Its lifespan is believed to have been 20 years or less. The name spelaeus was derived from the ancient Roman word “spelaio” meaning cave, which was allotted to Ursus spelaeus because most of the cave bear's residues have been found in caves.

A cave bear classification can be done in the following two ways:

• Scientific classification

• Taxonomical classification

Now, let us understand these two classifications one by one in detail.

Below is the scientific classification of a cave bear

Cave Bear Scientific Classification

Cave Bear Taxonomical Classification

In the year 1774, a German pastor and palaeontologist, Johann Friedrich Esper portrayed Cave bear skeletons in his book Newly Discovered Zoolites of Unknown Four Footed Animals. 

At the same time, researchers considered skeletons could belong to apes, canids, felids, or even dragons or unicorns, however, Esper hypothesized that they belonged to polar bears. After twenty years, an anatomist at the Leipzig University, Johann Christian Rosenmüller provided the cave bear species with its binomial name. 

The bones were several that most researchers gave little attention to them. 

During World War, I, with the scarce of phosphate dung, earth from the caves where cave bear bones discovered was utilized as a wellspring of phosphates. When the "dragon caves" in Austria's Styria area were misused, for this reason, just the skulls and leg bones were kept.

Numerous caves in Central Europe have skeletons of Cave bears inside, for instance, the Heinrichshöhle in Hemer, the Dechenhöhle in Iserlohn, Germany. In 1966, a total skeleton, five complete skulls, and 18 different bones were found inside Jaskinia Niedźwiedzia (bear cave) in Poland. In Romania, in a Cave called Bears' Cave, 140 Cave bear skeletons were found in 1983.

Cave bear bones are found in numerous caves in the country of Georgia. In 2021 Akaki Tsereteli State University's understudies and teacher found two complete Cave bear skulls with molars and canines, humerus, three vertebrae, and different bones in unexplored Cave "Sakavria."

Ice Age Cave Bear

In August 2020 a 'totally saved' ice age cave bear carcass was found by reindeer herders in Russia. The protected remains were assessed to be somewhere in the range of 22,000 and 39,500 years of age with radiocarbon dating proposed to determine a more precise age. 

It is the solitary find of its sort with full delicate tissue preservation to such an extent that even the nose was as yet intact. The frozen cave bear was found on Bolshoy Lyakhovsky Island, part of the Lyakhovsky Islands archipelago. In a different disclosure, an all-around saved Cave bear cub was likewise found.

Cave Bear History

A giant cave bear was around 2.7-3.5 m (8.9-11.5 ft.) long and up to 1.7 m (5.6 ft.) at the shoulder and weighed between 225 and 500 kg. The feeding behaviour of the cave bear has widely been debated as varying paleobiological studies along with the different dietary inferences for the animal, ranging from carnivory to pure herbivory.

Cave Bear Physical Features

A 3.5 meters (11.50 ft) tall while raising up, the cave bear had a wide, domed skull with a steep forehead, as we can see in the image below:

Its heavy body had long thighs, enormous shins, and in-turning feet, making it comparative in skeletal construction to the brown bear. Cave bears were similar in size to the biggest modern-day bears. 

A male cave bear was around 350 to 600 kg (770 to 1,320 lb), however, a few specimens weighed as much as 1,000 kg (2,200 lb), while females gauged 225 to 250 kg (495 to 550 lb). Out of cave bear skeletons in museums, 90% are male because of a misguided judgment that the female skeletons were ”dwarf". A cave bear became a giant cave bear during glaciations and more modest during interglacials, presumably to change heat misfortune rate. 

Ice age bears lack a few premolars present in other bears; to redress, the last molar is extremely stretched, with advantageous cusps. The humerus of the cave bear was small in size to that of the polar bear, similar to the femora of females. The femora of male cave bears, nonetheless, bore more similitudes in size to those of Kodiak bears.

Cave Bear Distribution

Cave bear remains have been found in the following places: 

• England, 

• Belgium, 

• Germany, 

• Russia, 

• Spain, 

• Italy, 

• Greece and 

Ice age bears may have arrived in North Africa. A few nearby varieties, or races, have been depicted; dwarf races are known from certain districts. Stone Age people groups at times chased the cave bear, yet proof of that chasing is extremely inconsistent; it is exceptionally impossible that chasing by humans caused its termination. 

It shows up reasonable that most cave bears passed on in the extremely chilly winters during dormancy (inactivity); the remaining parts incorporate a huge extent of exceptionally young or exceptionally old bears and numerous specimens giving obvious indications of illness or disease. Eradication of the cave bear appears to have been a progressive cycle that was finished somewhere in the range of 28,000 and 27,000 years prior.

Cave Bear Habitat and Range

The cave bear's reach extended across Europe; from Spain and Great Britain in the west, Italy, portions of Germany, Poland, the Balkans, Romania, Georgia (nation), and portions of Russia, including the Caucasus; and northern Iran. 

No hints of cave bears have been found in Scotland, Scandinavia, or the Baltic nations, which were totally canvassed in broad glacial masses at that point. The biggest counts of cave bear remains have been found in Austria, Switzerland, northern Italy, northern Spain, southern France, and Romania, generally compared with the Pyrenees, Alps, and the Carpathians. 

The tremendous number of bones found in southern, central, and eastern Europe has driven a few researchers to figure Europe may have once had crowds of cave bears. 

Others, nonetheless, bring up that, however, a few caves have thousands of bones, they were amassed over a time of 100,000 years or more, along these lines requiring just two deaths in a cave each year to represent the huge numbers. 

The cave bear occupied low mountainous regions, particularly in locales wealthy in limestone caves. They appear to have stayed away from open plains, inclining toward forested or forest-edged terrains.

Prehistoric Cave Bear

• Though the remains of a cave bear can be traced back to the Late Pliocene times, i.e., a Pliocene Epoch continued from 5.3 million till about 2.6 million years ago). In European cave deposits, the remains of more than 100,000 cave bear species have been found. 

• In 2013 a mitochondrial DNA succession of a cave bear was reconstructed by a gathering of researchers from a bone fragment found at Atapuerca's Sima de los Huesos ("Pit of the Bones") cave in Spain. The fragment was dated to over 300,000 years prior, which made the genome among the oldest ever at any point reconstructed outside of a permafrost climate.

Frozen Cave Bear

Researchers at the North-Eastern Federal University in Yakutsk, Russia, declared on Saturday the revelation of a very much safeguarded cave bear on the New Siberian island of Bolshyoy Lyakhovsky, Anna Liesowska reports for the Siberian Times. 

The adult bear carried on with its life at some point in the last Ice Age, simultaneously as enormous creatures like wooly mammoths, mastodons, and saber-toothed tigers. At the point when the bear passed on, permafrost saved its delicate tissues, organs, and fur, making it the best-saved illustration of a cave bear found at this point. Most cave bear stays found so far have been odd bones and skulls. 

Circumstantially, a preserved cave bear cub was as of late found on the Russian territory, the college says in a proclamation. Utilizing the two disclosures, researchers desire to become familiar with cave bears' lives. 

The entire adult frozen cave bear body is "the solitary find of its sort," scientist Lena Grigorieva says in the college explanation. "It is totally safeguarded, with all inner organs intact, including even its nose. This find is vital for the entire world."

Cave Bear Animal Facts

These terminated bears, in the same way as other, extinct animals, draw human consideration. We love a decent secret, and the celebrated past of cave bears wandering the earth interests many.  Below is the list of the amazing cave bear animal facts:

• Dragon Bones – The enormous skulls and teeth of cave bear fossils at first drove pioneers to the end that the bones were those of dragons. Discovering huge skulls covered up profound inside caves is in every case prone to spark the imagination. In certain regions, humans named caves with prolific cave bear fossils "dragon caves." 

• Cave Bear Diet Behaviour- Risky Plant-Eater – Despite its huge size and enormous teeth, researchers accept this bear was for the most part herbivorous. While it was conceivable omnivorous whenever offered the chance, in the same way as other current bear species, their essential feeding pattern was plant matter. Scientists contemplating the teeth of these fossils inferred that they probably fed on generally extreme vegetation. 

• Male Versus Female – Like numerous animal species, cave bears showed sexual dimorphism. This implies you could differentiate between male and female effectively by taking a gander at them. Male cave bears were a lot bigger than females. Indeed, they were such a great deal bigger than researchers accepted females were basically "predominate" adaptations of males.

• Productive Fossil Remains – Even you may picture fossils as uncommon remaining parts found once-in-a-lifetime, cave bear fossils are a long way from strange finds. Indeed, researchers have discovered countless cave bear fossils in Europe alone! There are such large numbers of these fossils that, during World War I, researchers bubbled hundreds to extricate phosphates.

Scientists researched and closely examined the feeding behaviour of the extinct Cave Bear. From the isotope composition of a bear bone’s collagen, they found that giant cave bear mammals subsisted on a purely vegan (an animal that eats pure vegetarian food even excluding the dairy products) diet. The research team proposed that it was their strict diet that led to the Cave Bear's extinction around 25,000 years ago.
