Pleistocene Polar Bear - Ursus maritimus tyrannus Ursus maritimus tyrannus was a very large fossil subspecies of the polar bear that descended from an Arctic population of brown bears. Its name in Latin means Tyrant Sea Bear. Initially the isolated brown bears were no different than the variations of brown bears of that time period. Because litters of cubs can show significant species variations in hair color and hair thickness, this gave certain individuals a survival advantage passed on each generation. Eventually skull changes and even changes in dentition occurred leading to the smooth and rather quick evolution of U. maritimus tyrannus. U. maritimus tyrannus was considerably larger then its modern relative. If everything is scaled out correctly from its remains, it would had been 183 cm (6 ft) at the shoulders, 3,6 m (12 ft) long and would have weighted an average of 1.2 tons, making it the largest bear "and one of the largest mammalian carnivores to ever walk on land". Its tremendous size makes it even bigger than the other "largest" mammalian carnivores that ever lived, including Andrewsarchus, Agriotherium, and Arctodus simus. It's speculated that this gigantic bear would, due to its formidable size and strength, have preyed on mammoths which also lived during the time. ![]() Daeodon shoshonensis Daeodon, one of the largest, if not the largest, entelodont artiodactyls, lived 25-18 million years ago in North America. The 3.6 m (12 ft) long, about 1.8 m at the shoulder, 90 cm long skulled, 600 - 1000 kg mass animal strongly resembled a giant, monstrous pig or warthog, possessing huge jaws with prominent tusks and flaring cheekbones. It possibly was a huge, bone-crushing scavenger and predator, found at Agate Springs Quarry. It had long skull bones under its eyes and bony protrusions on the lower jaw, not dissimilar to the 'warts' of the warthog, which may have supported jaw muscles. The well-known genus Dinohyus ("terrible pig") has now been synonymized with Daeodon, as the latter is the earlier name, having priority. ![]() ___________________________________________________________________

UMT is to big. 200 kg extra is a lott when your opponent weighs only a ton. But still, the Terminator Pig should be ale to put up a good fight. It's a sturdy animal with a vicious bite. UMT wins 60% of the time. |

Prehistoric Cat, that size is not accurate. There is no way any entelodonts had a 1,5 m long skulls as that would be larger then T.rexs skull. The largest entelodont skulls were about 1 m long (still pretty huge) and daeodon typically measured about 7 feet at the shoulders, certainly not 3 m at shoulders. Trust me if Daeodon was so large I would be the first one to sugest a match-up between it and T.rex. |

But how could a Giant 2.1m tall Entelodont only weigh 600kg-1000kg? |

I vote for Daeodon since one bite could cripple the Bear. But I give the Bear a good chance. |

Al right in the prehistoric predators Daedon was mentioned to be 4-5 times the size of Archaeotherium. Now Archaeotherium was typically 270 kg in mass. So based on that it would be 1080-1350 kg which is in the weight-range of a large UMT. |

This is the average size for Daeodon? |

I assume it is. Daedon was about the weight of a black rhino and black rhinos does have this weight-range so I assume that the average Daeodon weighted that much and certianly if it was 2,1 m at the shoulders. |

![]() ![]() They are both similar in size. However the Polar Bear weighs more, and looks more muscular. I'm going with the Polar Bear 6/10. It would be close. |

Never mind. The comparison above is better than the one I posted. I'm think it would be 50/50 now. |
