Dinocrocuta gigantea, the terrible hyena, but close study of the genus has seen it placed within the Percrocutidae, a group that is separate to hyenas, and is closer to felids (cats) and nimravids (false sabre toothed cats). They lived during the late Miocene in Eurasia and were about 2 m. long and stood 1.2 m. ( 3 feet 11 inches ) tall. by Chen Yu

But it would be decades before anyone realized the fossils came from a previously unnamed species of prehistoric cat. John Orcutt, now an assistant professor of biology at Gonzaga University, came across them in 2008 at the Museum of Natural and Cultural History in Eugene, while working on his doctorate at the University of Oregon. Orcutt, whose focus was on climate change and mammal evolution, said he kept the unusually large arm bone “on the back burner” as he finished his doctorate. He eventually collaborated with Jonathan Calede, assistant professor of evolution, ecology, and organismal biology at Ohio State University, to identify the cat. Their study was published in May in the Journal of Mammalian Evolution. The largest of the seven Machairodus lahayishupup arm fossils available for the analysis was more than 18 inches long and nearly two inches in diameter. By comparison, the average modern adult male lion’s arm is about 13 inches long. In adulthood, the Machairodus lahayishupup probably weighed between 600 and 900 pounds, more than four times the size of a mountain lion.

siberiantimes.com/other/others/news/wildlife-experts-angry-and-sad-after-rare-amur-tiger-is-fed-by-motorists/ Wildlife experts angry and sad after rare Amur tiger is fed by motorists By The Siberian Times reporter26 May 2021 Two men shared a video of feeding spicy pork and sausages to one of the endangered predators. The Amur Tiger Centre has condemned motorists who filmed themselves feeding an adult Amur tiger they met on a drive across Primorsky region. The Far Eastern experts, who have spent years bringing the endangered predators back from extinction, and take a lot of measures to prevent potential conflicts between humans and tigers, said they were bitterly disappointed with the video. ‘When will you smarten up, people? Now this appeared a good-natured step, like ‘LOL we fed a tiger’. But once a tiger understands the link between food and humans there will be screams ‘Help! Save! Tiger came to a residential settlement!’ ‘Under other circumstances we would have used a well-known phrase by Sergey Lavrov (**** imbeciles!, The Siberian Times), but now we’ll just say that we categorically condemn such behaviour,’ the team wrote on its social media.

African and Asian leopards are more genetically differentiated from one another than polar bears and brown bears. "Researchers mapped the genomes of 26 leopards which account for eight of nine living subspecies. The team sourced some of the genetic material from leopards in the Natural History Museum’s collection." "Genome analysis indicates that current differentiations in leopard subspecies just don’t hold water. While nine subspecies have been officially identified, the study shows that, for example, Indian and Sri Lankan leopards are so closely related that they could be considered as a unified evolutionary significant unit." “The answer must now be a resounding no when it comes to African and Asian populations. There is a risk of reducing genetic diversity when crossing a leopard that specializes in living in hot deserts, for example, with another that has adapted to frigid mountain conditions,” Havmøller says. “You are likely to create offspring that are not well adapted to either habitat. On the other hand, our results demonstrate that there might be a solid foundation for interbreeding some of the more genetically similar Asian subspecies.” wildfact.com/forum/topic-on-the-edge-of-extinction-d-the-leopard-panthera-pardus?pid=148344#pid148344

Looks like polar and brown bears are more closely related to each other than African and Asian leopards are. That means a polar bear should be included in the brown bear subspecies.

Looks like polar and brown bears are more closely related to each other than African and Asian leopards are. That means a polar bear should be included in the brown bear subspecies. Ever since learning that polar bears are brown bears perfectly adapted to the arctic, and that they are genetically still brown bears, I have thought the same thing - Ursus arctos maritimus.

That is why old polar bear have a bit of brown tinge on parts of their fur.

Back to topic on big cats, do you guys notice any physical difference between African and Asian leopards?

Question for any member "in-the-know".... what is the confirmed recorded weight of a Bengal tiger?

Question for any member "in-the-know".... what is the confirmed recorded weight of a Bengal tiger? There's one specimen that weighed 288 kg with an empty stomach. But I think it was a cattle killer. horribilis may give further details.

According to WildFact; the largest Bengal tiger ( official weight ) was 272 kg or 599.66 pounds. ( we can call it 600 pounds ).

/\ 599.66 pounds and 600 pounds have no noticeable difference anyway. I am sure the weight of many animals are rounded up.
