Nice find King Kodiak. One of the last Mexican grizzlies killed in 1976 while feeding on a cougar kill in Sonora, Mexico.

THE MEXICAN GRIZZLY MAY NOT BE EXTINCT
Great find King Kodiak. If this turns out to be true - major news. |

"The mexican silver grizzly is the smallest grizzly species. Even being smaller, this can often weigh over 226 kilograms".
"This slow graceful animal can charge at high speeds and has been known to run faster at hill upwards than downwards. They can run as fast as 65 km per hour, fast enough to catch horse or deer."
"The strength is immense. One story told that a mexican grizzly killed a horse and dragged it 90 metres and once a grizzly killed a bison and dragged it off."
"The one of the lastest grizzly bear of norther mexico was shot by hunters in 1964. That was a mama bear with two cubs."

226 kilograms is equal to 498.24 pounds. Even if the grizzly was nearly 500 pounds that drug a dead horse 295 feet, this is impressive. If the bison a Mexican grizzly drug even for a few feet was a full-grown animal, cow or bull, still impressive. There is no disputing the great strength of a grizzly. *Something to consider. The Mexican grizzly shared his environment with the jaguar. Perhaps "share" should be substituted with another word. |

Mexican bears shot by hunters. (Maybe Mexican black bears)  (This one is surely a grizzly bear)  |

Long ago, when Grizzlies and jaguars met in the American Southwest, this should have happened indeed:

Wildlife in Danger By James Fisher, Noel Simon, Jack Vincent ยท 1969 Source: www.google.dz/books/edition/Wildlife_in_Danger/iQjpE8TzUrsC?hl=frPage 67 MEXICAN GRIZZLY BEAR Ursus nelsoni The most powerful , fearless , and majestic of all the native mammals of Mexico is unquestionably Ursus nelsoni , the indigenous grizzly bear . Although somewhat smaller than its northern relatives , it is nevertheless a massive animal weighing up to 670 pounds or more and often attaining a length of over 6 feet , although the size of individuals varies considerably . Adults are distinguished by a huge head, small ears , distinctive shoulder hump , and claws that , un- like those of the American bear , U. americanus , 2 are only slightly curved . The general colour consists of varying shades of brown . The Mexican grizzly appears to have pre- ferred the foothills to the higher parts of the mountains , and was usually found in the belt of scrub oak beneath the pine forest , the explana- tion being that in such forest its favoured food could not be obtained . The bear is omnivorous , eating nuts , acorns, roots , shrubs , and a wide variety of other vegetation , as well as insects , honey , and occasionally small mammals . Its chosen habitat therefore coincided with the zone most favoured by man for his domestic animals , a situation that resulted in conflict , inevitably to the bear's disadvantage . Little is known of the breeding biology of the Mexican grizzly , but it is thought that breeding age is not reached until the fourth or fifth year and full growth not until the age of eight or ten . Only rarely do litters consist of more than one or two cubs , and mature females do not normally give birth more often than every second or third year . The young develop even more slowly than those of American " black " bears , and remain under maternal care and control for two complete seasons before they are capable of an independent existence . This low reproductive rate explains the inability of the species to with- stand excessive exploitation . The Mexican grizzly remained undescribed until 1914 , but had been known more than a century before , when it existed in northern Lower California and parts of New Mexico and Arizona . It is not certain when it was extermi- nated in Lower California , but no specimen has been recorded there for several decades. In the northern Sierra Madre grizzlies were abundant in 1855 when the international boundary between the United States and Mexico was being marked . The animal was said to be particularly numerous in the San Luis Mountains and at Los Nogales . Even as recently as 1892 , when the second international Boundary Survey was in process , grizzlies were still plentiful in the San Luis Mountains . "No famous animal ( or group of animals ) has a more confused classification than the great bear of North Africa ( where it is now extinct ) , Europe , northern Asia , North America , and northern Mexico . Its vernacular names are reasonably stable : in the Old World " brown bear " , in western Alaska " big brown bear " , in the rest of its New World range " grizzly " . Through the years , though , at least 108 specimens have been first named as full species and at least fifty - one specimens first named as subspecies - excluding a large number of fossil forms . Few of these are even valid as races among what is now a very broadly scattered world population , with many relict sub - populations , some of which have become extinct in historical times . The European systematic authorities prefer to regard all as forms of one highly variable species , Ursus arctos . The American authorities , such as Hall and Kelson in 1959 , prefer to leave the question in suspense . Ellerman and Morrison - Scott , in 1951 , from a large number of synonyms , accepted only seven races as valid in the whole Old World , and cite even U. a . crowtheri , the Atlas brown bear , known to have existed in western North Africa , but certainly extinct for over a century , as a doubtful subspecies . On the other hand , Hall and Kelson list as many as eighty - six other forms as peculiar to the Americas , in an alphabetical order ( no fewer than seventy - six of them as full species ) , though they admit that " it seems almost certain that the majority of these are at most subspecifically distinct " and suggest that some names may even apply just to family groups . By European standards of systematics , these names ( and a few others that are certainly synonyms of them , being later names for the same form ) may probably belong to only about nine valid races . Sup- posing we accept the American populations as all of one species , we may arrange them under the name Ursus arctos if we want a broad classification , or under the first American name for a grizzly bear if we hold them in a separate species . This is Ursus horribilis of the naturalist Ord , published in 1815 ; and there is little doubt that the form named Ursus nelsoni by Clinton Hart Merriam in 1914 , the Mexican grizzly , is a valid subspecies of it even if Merriam was J.F. perhaps unduly concerned with divisions."
"This native bear of North America and northern Mexico is quite a different species unknown in the Old World . It shares nearly all the present range of the grizzly and occupies eastern North America ( including Newfoundland ) besides . It has eighteen races , according to Hall and Kelson , one of which , U. emmonsi, the glacier bear of Alaska , is of some concern for the Red Data Book . The commonly used vernacular name of the American bear is " black bear " , which is almost as confusing as the scientific names of the grizzly , for the American bear has black , brown , and cinnamon colour phases and these can be found in the same litter ." |
