why the Saber Tooth Tiger is known as the Ice Tiger
Scientists believe that this tiger had experienced the last period of the ice age with mammoths and promised other types of mammals, so it was called the ice tiger with another type of tiger that lived in the same period and became extinct with the end of the ice age
The Ice Tiger or the Saber-Toothed Tiger
The “Ice Tiger, commonly named” Saber-Toothed Tiger “(the scientific name: Smilodon) is an extinct species of the fibrous tooth. It is one of the most famous prehistoric mammals and the most prominent feline sword fangs among all the other ancient species. In the West, the individual is called the “saber-toothed tiger” in the West, and this name was translated incorrectly into the Arabic language, so the “tiger sword-tusk” became, in line with the common mistake of mixing the tiger and the tiger, but in reality Not closely related to the tomb or other contemporary felines. Ice Tiger lived in the Americas during the earliest modern era (the Pleistocene), that is, during the period spanning 2.5 million years to about 10,000 years. The contemporary designation of this genus was given in 1842 based on some fossils discovered in Brazil. Scientists currently recognize three types of Smilodon: the slender Smilodon gracilis, the deadly Saber-Toothed Tiger fatalis, and the destructive Ice Tiger (Scientific name: Smilodon populator). It is possible that the last two types are descended from the slender Ice Tiger, which in turn may be descended from mepanterone. The largest group of Ice Tigerfossils was discovered in the La Praia pits near Los Angeles, California, in the United States.
they are very present in popular culture, and we will not forget to the point that almost everyone knows Diego, the Ice Tiger star of the saga of animated films The Ice Age.was a distant relative of the felines that we know live on planet earth in the early 21st century, apparently, the domestic cat is a closer cousin to the tiger, than the latter to the Ice Tiger, it is one of the last cats whose lineage (the Machairodontinae) became extinct at the end of the last Ice Age about 10 millennia ago.
Ice Tiger Description
Ice Tiger better known as the saber-toothed tiger is among the fossils reminiscent of the most agile and ferocious carnivores of the typical Pleistocene megafauna (i.e. animals weighing more than 45 kg). The taxonomic location of this bold mammal is within the group of cats. A relatively large size (more than 1 m long), a weight that could range from 360 to 450 kg, and a jaw opening of up to 120 degrees, are sufficient morphological characteristics that make clear the hunting ability of this big cat. Its skull was made up of an extensive foramen positioned below the diastema (figure 1); however, the diagnostic feature that makes its name famous is a pair of sharp, paired, and serrated fangs, as well as a very long postcanine diastema.
Ice Tiger was around the size of modern big cats but was more robustly built. It had a reduced lumbar region, high scapula, short tail, and broad limbs with relatively short feet. Ice Tiger is most famous for its relatively long canine teeth, which are the longest found in the Ice Tiger cats, at about 28 cm (11 in) long in the largest species, S. populator. The canines were slender and had fine serrations on the front and backside. The skull was robustly proportioned and the muzzle was short and broad. The cheekbones (zygomata) were deep and widely arched, the sagittal crest was prominent, and the frontal region was slightly convex. The mandible had a flange on each side of the front. The upper incisors were large, sharp, and slanted forwards. There was a diastema (gap) between the incisors and molars of the mandible. The lower incisors were broad, recurved, and placed in a straight line across
Ice Tiger Habitat
These Ice Tiger were widespread and utilized many different types of habitats for survival. Scientists believe that Ice Tiger cats lived everywhere from savannahs to steppes, subtropical forests, woodlands, plains, mountains, and more. Different species had different habitat preferences, and some were more successful and widespread than others.
Ice Tiger Diet
In North America, Ice Tiger hunted large herbivores such as bison and camels, and it remained successful even when encountering new prey species in South America. Ice Tiger is thought to have killed its prey by holding it still with its forelimbs and biting it, but it is unclear in what manner the bite itself was delivered. Scientists debate whether Ice Tiger had a social or a solitary lifestyle; analysis of modern predator behavior as well as of Ice Tigers fossil remains could be construed to lend support to either view. Ice Tiger probably lived in closed habitats such as forests and bush, which would have provided cover for ambushing prey. Ice Tiger died out at the same time that most North and South American megafauna disappeared, about 10,000 years ago. Its reliance on large animals has been proposed as the cause of its extinction, along with climate change and competition with other species, but the exact cause is unknown.
The behavior of the Ice Tiger
The social behavior of these cats is a highly debated conversation. There are a number of theories that suggest these cats lived in groups. Because researchers found them in great numbers in the La Brea Tar Pits, they posit that distress calls of potential prey attracted them to the area.
Distress calls attract modern-day predators to hunt in groups. Finally, archaeologists have found fossils of multiple individuals in close proximity to one another. This also suggests that they might have lived in groups.
Ice Tiger Hinting
An apex predator, Ice Tiger primarily hunted large mammals. Isotopes preserved in the bones of S. fatalis in the La Brea Tar Pits reveal that ruminants like bison (Bison antiquus, which was much larger than the modern American bison) and camels (Camelops) were most commonly taken by the cats there. In addition, isotopes preserved in the tooth enamel of S. gracilis specimens from Florida show that this species fed on the peccary Platygonus and the llama-like Hemiauchenia.In rare cases, Ice Tiger may have also targeted glyptodonts, based on a Glyptotherium skull that bears elliptical puncture marks consistent with the size and diameter of its canine teeth. This was a juvenile glyptodont with an incompletely developed cephalic shield (head armor). Isotopic studies of dire wolf (Canis dirus) and American lion (Panthera leo atrox) bones show an overlap with S. fatalis in prey, which suggests that they were competitors.More detailed isotope analysis, however, indicates that Ice Tiger preferred forest-dwelling prey such as tapirs, deer, and forest-dwelling bison as opposed to the dire wolves’ preferences for prey inhabiting open areas such as grassland. The availability of prey in the Rancho La Brea area was likely comparable to modern East Africa. As Ice Tiger migrated to South America, its diet changed; bison were absent, the horses and proboscideans were different, and native ungulates such as toxodonts and litopterns were completely unfamiliar, yet S. populator thrived as well there as its relatives in North America.The differences between the North and South American species may be due to the difference in prey between the two continents. Ice Tiger probably avoided eating bone and would have left enough food for scavengers. Ice tiger itself may have scavenged dire wolf kills. It has been suggested that Smilodon was a pure scavenger that used its canines for a display to assert dominance over carcasses, but this theory is not supported today as no modern terrestrial mammals are pure scavengers.
Ice Tiger Fangs
The Ice Tiger carried a double-edged sword in their jaws. These animals present a great example of how evolution works. Natural selection was modeling a body, a denture and a constitution specialized in killing large prey.to find apparently perfect solutions. One of them was being able to open its mouth almost 180 degrees to be able to bite its prey, although its bite was less strong than that of a lion. These extinct mammals had a very different way of killing their prey than today’s cats. Its elongated and flattened fangs were perfect for causing quick death by going through the arteries and trachea or even the lungs if they bit on the side. Instead, today’s big cats kill by suffocation, biting the neck of the prey and holding the bite during long and dangerous minutes of agony.
The fangs of Ice Tiger also had a weak point. They were more fragile than the conical canines of today’s cats. Analysis of a good number of smilodon specimens —Ice Tiger that lived in America until about 10,000 years ago — has shown that these felines snapped their fangs much more frequently than they do today. The reason for this problem is not clear. Some experts believe it is due to the inherent violence of hunting, especially since Ice Tiger was a specialist in killing mammoths, mastodons, giant sloths, and other megafauna species during the last ice age. The other option is for canine breaks to indicate an increasing lack of prey that led Ice Tiger to eat bone and not just meat, as they usually did, and their teeth didn’t hold up well.
Ice Tiger Extinction
Along with most of the megafauna Pleistocene, Ice Tiger became extinct 10,000 years ago in a quadruple extinction event. Their extinction has been associated with the decline and extinction of large herbivores, which have been replaced by smaller and leaner ones such as deer. Thus, Ice Tiger would have been very specialized in hunting large prey and might not be able to adapt. A 2012 study of wearing Ice Tiger found no evidence that they were limited in food resources. Other explanations include climate change and competition with humans (who entered the Americas at the time of Ice Tigers disappearance), or a combination of several factors, all of which apply to the general Pleistocene extinction event, rather than Ice Tiger extinction. Cats.
Some of the early authors hypothesized that cats with the last sword tooth, Ice Tiger and Homotherium, became extinct by competing with the fastest and most general embryos that replaced them. It has even been suggested that predators with a sword were inferior to modern cats, as growing fangs were believed to prevent their owners from feeding properly. However, rapid embryos, such as the American Lion and the American Cheetah, became extinct during the late Pleistocene era. The fact that the sword teeth have evolved many times in unrelated lineages is evidence of the success of this feature.
The most recent Ice Tiger samples recovered from the Rancho la ‘Priya tar pits ” date back to 13025 years, and the most recent Ice Tiger remains are in the cave of Cueva del Medio, near the town of Soria, the northeastern province of Ultima Esperanza, Magallanes region in the south – most of Chile goes back to what Between 10935-11209 years ago. The last carbon-14 date for S. Fatalis reported was 10,200 years BP for the remains of the first American cave in 1971; However, the most recent “reliable” date was given as 11,130 BP.
The last Great Ice Age
Approximately 40,000 years ago, in the latitudes of the northern hemisphere, a geological process known as the Great Ice Age was generated, which would lead to what is familiarly known as the Ice Age. During this temperature drop event, the populations of the largest animals were the most vulnerable, so many of them began to migrate from north to south (and to a much lesser extent some species also migrated from south to north). This great migration included the passage of several generations of mammal herds through the Mexican territory. A couple of years ago, this Ice Age in Mexico was recreated in an excellent series produced by Canal Once. This television production was the object of international recognitions and awards because it clearly and elegantly documented what this geobiological event should have been based on the fossil record of Mexico. 14,000 years ago, large mammals such as mammoths, mastodons (Mammut americanum), glyptodonts (Glyptotherium), camels (Camelops western us), and sloths (Megalolonyx Jeffersonian), usually extinct up to 80 % only in North America (Lyons et al., 2004), and within such a short period that some specialists have considered it only as a “geological moment”.
Although the causes of the extinction of this remarkable North American megafauna have been the subject of heated debates, the topic has focused on evidencing whether the cause of the progressive extinction of many trophic communities that then inhabited these latitudes was excessive hunting by different human tribes or was global climate change. Apparently, human populations first entered the American continent during the megafauna extinction period. An alternative explanation is that climate change in the Final Pleistocene caused extinction, as habitats were radically altered. There is a theory known as the Dynamic Equilibrium Model on species richness (Huston, 1994), which stresses the importance of the life cycle and phenotype of extinct mammals. This model proposes that environmental disturbances are the most important cause of extinction. Even the most abrupt climatic changes are known to have occurred between 16,000 and 11,000 years. However, this does not exclude excessive hunting.
the last exist of the Ice Tiger
The “Ice Tiger” lived just 20,000 years ago in South America and is supposed to have died out approximately 8,000 years ago, at the end of the Ice Age. The saber-toothed tiger inhabited the area from the current US state of California to all of South America. Most of the remains have been located in an area near the city of Los and some places in Mexico Angeles. Recent studies reveal that the Ice Tiger was not as ferocious as previously thought and possibly its physical weakness was what did not allow it to adapt to the climatic changes in its habitat.
