I'm not sure whrer else it lived, but the sabre tooth tiger (smilodon) has been found in the La Brea tar its in Los Angeles and a full skelton is California's State fossil.,  See also the following site: http://www.bluelion.org/smilodon.htm

Largmouth bass are native to most lakes and rivers east of the rockies.  Though the recent past they have started introducing the larger Florida strain and hybrids to the fishery.

The entire State of Utah is within cougar range-see link below for the map.  That being said, they *used* to be more concentrated in the SE portion of the State, around where I was raised and hiked-Now, they are becoming more prevalent all along the Eastern side- But a short answer is that you can find them anywhere in Utah.\n\nhttp://www.dlia.org/atbi/species/animals/vertebrates/mammals/Images/NA_Range_Maps/Puma_concolor_NA640.jpg

There is a relative of the raccoon known as the ringtail (Bassariscus astutus) which lives in the southwest.  It is about the size of a cat, and slender of body, with a long, black and white striped, bushy tail.  Nocturnal and shy, they feed mostly on berries, insects and rodents.  Another name for them is miner's cat, because they were often kept as pets by prospectors and miners in the Old West.\n\nThe ringtail is the state mammal of Arizona.\n\nA closely related critter, the cacomistle (Bassariscus sumichrasti) lives in Central America.

Giganotosaurus, in Argentina. They weighed two tons more than T rex. They hunted giant herbivores that weighed 92 tons, and were called....Argentinasaurus.

If you mean where can you find info about them I would think any animal encyclopedia would be helpful.  There are horned toads (really lizards), other lizards, various snakes, desert rodents, scorpions and spiders, mountain lions, road runners, eagles and hawks and of course other birds.

The "rex" (as they are called) does live in parts of California.  I was bit by one and had to have skin removed because it was necrotic.  You can also have sores from sugar issues but these are usually on the legs and feet.  If you have the means, try to contact a spider bite clinic or look online for places that deal specifically with spider and snake bites.  These clinics usually have doctors that are trained in both specialties and they may be able to help you more than a regular ER doc.  From what I read, the female is more potent than the male and can live longer under harsher conditions.  If you still had venom in your system then I would be seeking help from a lawyer because if they treated you and misdiagnosed you - then gave you false information, they are liable.\n\nGood luck!  If you get a chance, let me know how this works out.  I know how much a bite can hurt ...

Tiger sharks are aggressive sharks and are commonly found in the Pacific Ocean. The Great White is probably the most feared and largest. They are known to travel all around the Pacific.

The Timber Rattler is native (if rarely seen) in the Eastern US, and Massachusetts is included in its range, but because of the high population density of Mass. (and the long-time tendency of people to kill rattlesnakes around their houses) I imagine that you would be hard pressed to find any rattlesnakes there.\n\n**Update**\nI found a website with the timber rattler's range laid out on a map: http://www.dec.state.ny.us/website/dfwmr/wildlife/endspec/tirafs.html

Well, the GABI (Great American Biotic Interchange) went both ways, and several families of mammals from North America came to South America, and viceversa. However, only few native South Americans remain today in North America (NA), whereas many originally Holarctic families are thriving in South America (SA) at present. \n\nThe above answerer has outlined the three major "strata" defined by GG Simpson for the mammals of SA. The "original" South American mammals before the GABI included marsupials (shared with Australia, but forming a distinct cohort with different families) but also the exclusively South American xenarthrans (although there is a possible fossil anteater from Europe), and the Caviomorph rodents (closely related to the hystricognathous African rodents). In addition, there were some carnivores that had made it from NA. \n\nAfter the Panama land bridge appeared, the GABI was intense. North and South American faunas mixed and they appear to have coexisted for a long time. \nThe subsequent Pleistocene extinctions involved groups of both origins, but the South American natives were more intensely affected. Among the hypotheses to explain this,  interspecific competition has been mentioned, but also climatic changes. \nFirst of all, direct competition is _very_ difficult to prove, and more so with respect to fossil remains from strata that may not be exactly coeval. A more recent and preferred explanation involves a little paleoclimatology. \n** During the glaciations (and other stressful periods), South American conditions were more benign, because the continent is closer to the Equator, whereas environments in NA were much harsher, facilitating the extinction of the South American immigrants, along with many native North American giant forms. \n**In addition, the Central American corridor, which had been at first a savanna-like environment that permitted passage, later in the Pleistocene became more like a tropical forest. Then many cursorial (running) animals that inhabited open areas were unable to "cross the bridge". The giant ground sloths and glyptodonts were trapped in NA, and when climate and vegetation kept changing toward colder and drier conditions, became extinct.\n\nAnimals left from this: \nAmong the original South American natives, only the xenarthrans (sloths, armadillos, and anteaters) and marsupials (opossums)[early inhabitants], and the caviomorph rodents (originally derived from their African relatives) [second stratum colonizers] are alive today. The immensely diverse native ungulates went extinct, along with the representatives of the megafauna (giant sloths, glyptodonts, etc). At least one species of armadillo (Dasypus novemcinctus) is expanding its range in NA today, and the opossums (I remember Didelphis virginiana, not sure if there are others) are well established there. Caviomorph rodents also occur in NA (porcupines, genus Erethizon), but are mostly confined to Central America. \nThese are the South American contributions to North American fauna. In contrast, about 50% of the South American mammal genera have North American origin.\n\nWith respect to birds, at least the Passeriformes Suboscines are South American in origin, but I have no idea _when_ they colonized NA. They include the Tyrannidae (tyrant flycatchers). Other birds with Neotropical origin are the hummingbirds (Trochiliformes or Apodiformes).\n\n---------------------\nUpdate:\nMmm... I’m not sure what you call “non-speed strategies”. Predators? Running forms such as ungulates? There were many native ungulates in South America and they went extinct; also many marsupial predators such as the marsupial sabertooth “cat”  that also disappeared. Many caviomorph rodents are cursorial (capybaras, agoutis, etc).\nI would relate it more to size. Size _is_ a constraint because large animals have different energetic balance and need large amounts of food and room. And those went extinct in both co

In North America the red-sided garter snake (Thamnophis sirtalis parietalis) reaches as far north as the southern tip of Alaska, and portions of the boreal forest across western Canada including parts of the Northwest Territories.  \n\nIn Europe and Asia, the adder or common viper (Vipera berus) can actually be found north of the Arctic circle in a few areas of Russia and Scandanavia, but still isn't really found on the tundra.
