rzeszow.wyborcza.pl/rzeszow/7,34962,8801946,niedzwiedzie-mialy-uczte-zjadly-mloda-zubrzyce.html?disableRedirects=true Another report of the same incident: "The Bieszczady bison, even though they are rightly called "emperors' of the forests, sometimes fall prey to predators. It happened that young bison disconnected from the herd were gnawed by packs of wolves. This time, a few-year-old European bison fell prey to the bears in the Baligród Forest District." "The dead animal, partially eaten, was found on Saturday, December 4, in the Roztoki forestry by the forester Jan Duell, who went for a forest walk with his son Kajetan. Numerous traces around indicated bear feeding. The forester installed a camera with a photocell on one of the nearby trees, which recorded the view the next night, confirming the assumptions. On the frosty night from Saturday to Sunday, three bears came to the carcass; most likely a mother with two almost one year old cubs. On Monday, December 6, an autopsy and detailed examination of the dead bison were performed, which also indicated that the perpetrator was a bear.".... "This was evidenced by an extensive internal stroke in the area of the spine, which is a trace of a powerful bear's paw blow - says Marcin Scelina, a forester participating in the inspection. - A large amount of droppings and numerous lairs near the carcass indicate that the bears have been feeding here for many days. Traces of the European bison being dragged over a distance of several meters were also found, proving the enormous strength of predators." "Apart from bears, carcasses are also fed by ravens, buzzards, hawks and small forest birds."

Quote: "Looks like bears have strong jaws. Big cats have better killing bites." *Yes, designed for strangulation or suffocation of their prey... or for a quick bite to the base of the neck. *The big cats have stronger jaws than brown bears ( pound-for-pound ) but the bears teeth are thick and deep-rooted; better for brawling.

I also like to add that bears might have better crushing and shaking bites maybe even pound to pound while big cats have stronger jaws (the pressure coming from the canines to suffocate prey). Correct me if I am wrong.

Looks like the grizzly claws are very famous in america.

FINLAND ZOO: 300 KG MALE BEAR KILLS 100 KG FEMALE BEAR WITH ONE PAW STRIKE TO THE HEAD. IT BROKE THE SKULL:
A sad incident was experienced at Ranua Zoo today. A fight broke out between the two bears, in which the Milla puppy was killed when the old and large male bear Palle-Jooseppi hit it in the head.
One blow was enough. The skull of the Milla bear was broken and it died immediately, says Tommi Hinno, CEO of Ranua Zoo, to IS. According to him, a big male bear is always dangerous to other bears. The Milla bear that was killed weighed about 100 pounds, while the big male bear had gained almost 300 pounds. According to the price, the Milla bear was placed in the same paddock in the spring with the big Palle-Joseph, because the bear female Dooris got the puppies in the adjacent paddock. According to Price, Palle has lived in a pen with young females in the past. There have been few problems, but on Monday the bears were born into a fight in which Milla died. - At least in the near future, another bear will not be placed in the same fence as Palle-Joseph. The Dooris bear is also in its own pen with its puppies, Hinno says. Milla received a lot of attention when she was found badly hungry and exhausted just over a year ago as an orphan from Tohmajärvi in North Karelia. Its survival was considered a small miracle. Last winter, Milla was followed relentlessly because she couldn’t fall asleep for the hibernation in her new home at Ranua Zoo.

Some interesting indexes : The Brown Bear scores 84,09% and 162,84% in scapula area index and forelimb Proportions index respectively which are greater than what the lions (80,5% , 141,51%), tigers (80,4% ,147,79%) and leopards (76,05% , 148,75%) scored. This means that even at similar size, the brown bear has the potential to deliver a much stronger paw swipe than the big cats. Ofc we can add the brown bear's plantigrade stance and wider paws to make the felidae seem like harmless pillows in comparison.

Awesome! I would think that the brown bear's greater girth as well as his shoulder hump would also add to his paw-swipe advantage.

Zhao Yan is a ranger in the Hunchun Bureau of China's Northeast Tiger and Leopard National Park and has been working in conservation for twelve years. He says that the palm pads of male Amur tigers are typically from 10.5 to 13 cm wide. The largest palm pad width he has seen is 14.5 cm. That is from a giant male tiger! The huge male Amur tiger nicknamed "Beast" aka "The monster" tiger from the Khabarovsk territory in Far East Russia, who was famed for his immense size, had a huge palm pad width of 13.5 cm. But a male Amur tiger from Northeast China has a even larger palm pad width of 14.5 cm. Indicating that there are even bigger Amur tigers out there than the 'Beast'. *And then there is BIG
When it all boils down to paw size, claw size, and devastating strike force, neither a lion nor a tiger can compete with a brown bear.

Bear Claws; black, polar and grizzly bear claws The relationship of the polar bear and the grizzly bear is interesting. Polar bears are believed to have split off from the grizzly bear lineage approximately 150 000 years ago in a time of global climate cooling – arctic living skills became an advantage. So the polar bears stayed in the north, and the grizzlies enjoyed the warmer climes further south. Rarely did the 2 run into each other. Comparison of Bear claws ( left to right ) black bear claws (Ursus americanus), polar bear claw (Ursus maritimus), grizzly bear claw (Ursus arctos) and Kodiak bear claws.

shaggygod.proboards.com/ Mediolateral forces were significantly higher than would be expected for a large erect mammal, almost to the extent of a sprawling crocodilian. There may be morphological or energetic explanations for the use of the running walk rather than the trot. The high medial forces (produced from a lateral push by the animal) could be caused by frontal plane movement of the carpus and elbow by bears. Overall, while grizzly bears share some similarities with large cursorial species, their locomotor kinetics have unique characteristics. Additional studies are needed to determine whether these characters are a feature of all bears or plantigrade species. VGRF = vertical ground reaction force. *Brown bears share some similarities with large cursorial species, their locomotor kinetics have unique characteristics. *Vertical ground reaction forces is significantly more pronounced in the hindlimb,however,VGRF in forelim is still relatively high. "The high medial forces (produced from a lateral push by the animal) could be caused by frontal plane movement of the carpus and elbow by bears" It forced me to focused on the carpus of brown bears. Sylvie McKenzie said she was driving along a highway a few kilometres west of Jasper when she noticed two bears running along the road ahead.She said she slowed down to let the bears cross the road, but only the female bear did so. The second bear – a male – simply stopped and stared at her. McKenzie said she then started driving, putting her car between the two bears. Sylvie McKenzie Asked whether she has any advice for drivers caught in the same situation in the future, McKenzie had simple advice: 'Stop, turn around, wait for a few minutes and go back.' (CBC) "The male didn't like it at all, so he decided to take his feet, charge and hit my car with his two front paws," she said. "[He] just came and pounced on my car with full force and full speed." McKenzie said the car rocked violently when the bear hit it, giving her a close-up view of the bear’s face. "I could see his teeth, the drool on his face. I tried to speed up and put my foot on the gas pedal to get away as fast as I could." Later, she found grizzly prints all over the side of her car, along with two big dents and several scratches. It seem that carpal bone have a high resistance to mechanical deformation. Grizzly bear front paws are surprisingly heavy,maybe due to massive carpal bones? This is the most accurate description of the striking ability IMHO: "...The attack of a Bear is usually sudden and rapid, and he either tries to deal his opponent a blow with a forepaw by executing a rapid and violent movement to the side ,or he quickly trots up to his enemy ,suddenly lift himself on his hind-legs in the immediate proximity of his foe whom he tries to knock down with a violent stroke of the front-paw,or else he deals him a sound blow and gives him a quick bite..." A bear has a hard and tough paw which can withstand the repercussions of delivering a devastating paw-strike. A cat has soft paws designed for stealth.
