Sabertooth Cat Intro The sabertooth cat, also known by its scientific name Smilodon Fatalis, is considered a true form fossil. A fossil is considered a true form fossil when scientists recover fossils of the actual animal or animal part. These bones were oftentimes subjected to physical processes while still on the surface. These processes include heat, cold, wind and rain. When did it roam the earth Saber Tooth Cats lived during the Ice Age, around 10,000 years ago, existing for about 42 million years, from the Eocene Epoch to the end of the Pleistocene Epoch. They roamed the earth during the early to late Pleistocene era (1.6 to 10,000 years ago) along with other animals such as mammoths and mastodons, however fossils of other …show more content…
The tar pits were surrounded by grasslands, shrubby areas and pine forests. Sabertooth cats fed off of herbivores so they often times lived in areas like this because many of the plant-eating animals sabertooth cats relied on lived in these areas. Smilodons also preferred to live in closed habitats so that it was easy to ambush it’s prey while hiding in bushes. Fossils show some evidence that Sabertooths were social, perhaps even living in groups to care for one another. Fossil records also suggest that they lived in icy lands, as they lived during the end of the Dinosaurs and during the Ice Age. The Ending The Smilodon, the most recent type of saber tooth cats, went extinct about 10,000 years ago, around the time when Pangea began separating and breaking up. Sabertooth Cats did not go extinct due to lack of prey. However, around 12,000 years ago (end of the late Pleistocene) sabertooth cats, american lions, wooly mammoths and other gigantic creatures considered the “megafauna” went extinct. A die-off called the Quaternary extinction. A popular theory for the extinction is that the changing in climate during the end of the last ice age, human activity, or a combination of both killed off most large
In order to better understand these "implications," it is necessary to define and explain the major theories regarding North American megafaunal extinction. The two most widely supported theories are those of environmental change and overkill. Two theories finding less support within the field are those of hyperdisease and "keystone herbivores."
In many cases Savannah cats are known for being cute, furry and cuddlable but we need to respect them in their natural behavior tendencies to provide them a suitable stimulating environment. By doing so we have to encourage environmental enrichment for the physical and mental health for these Savannah’s. Having a proper environment increases these species brain activity, well-being, senses, stimuli, and relieves them from boredom. These cats tends to get physical, physiologic, and behavioral disorders for stress and lack of stimulation. It can cause these species to do urine marking, house soiling, owner directed aggression, behavioral over grooming, displacement activities and reduce comfort behavior. For Savannah cats are a cross between
In this period the Earth was very cold and there were multiple glaciers. It was a huge ice age. Scientists say that the reason for the ice age was because of a 100,000-year cycle related to the Earths orbit and shape. Mammals got very big and lived in cold grasslands. These animals were relatives of the elephants. They are mammoths and mastodons. The extinction of these animals was at the same time of the extinction of the ice age.
Due to the cooling climates, the forests began to transform into grasslands. New predators began evolving to be fit to chase animals in the grasslands. Cheetahs and leopards were among those animals. They had to adapt or starve. There was also new plant life in the oceans. Kelp began to grow in cooler waters. Sharks also began to develop new species. One species grew to be about fifty feet long. However, it became extinct about 1.6 million years ago.
Today’s domestic house cats sure have changed and traveled far from their old wildcat ancestors across the world. Cats have traveled halfway across the world and now live around the world in various breeds and sizes. Even though they live today in their domesticated form they still retain some of the traits that their ancestors bestowed upon them. The African wildcat is believed to be the ancestor of all domestic cats, and they’re even still alive to this day. Over thousands of years of speciation, domestic house cats came to be from these wildcat ancestors.

The Triceratops was living in the late Cretaceous Era. It lived about 68 to 65 million years ago. The Triceratops were said to live in the Wyoming, Colorado, and Canadian area, where they have cold winters. The Tyrannosaurs dominated all of their prey in North America at that time. Also giant penguin-like marine animals called Polycotylid Plesiosaurs appeared in the oceans towards the south. The Earth was still dominated by dinosaurs at that time. During the late Cretaceous Era, North America was slowly moving westwards, whic...
The National Geographic article “Siberian Tiger” by Joel Sartore highlights the escalating endangerment of Siberian tigers due to two main factors: destruction of the forests, and most prominently poaching (2014). Amur tigers primarily reside in eastern Russia, China, and North Korea, where they experience bitter climates, resulting in low human density and vast woodlands to roam (Sartore, 2014, p. 1). Yet, what seemingly appear to be advantages in reality are downsides, since timber industries expand and demolish these vast ecosystems (S...
Bison have been around for 10,000 years. Their ancestors where known as giant bison and they were hunted by the paleoindians that came over on the Bering Strait. The giant bison however became extinct because the paleoindians hunted them and at the end of the last ice age, most of the vegetation they fed off of was destroyed. Dwarf bison, the bison that are around today, survived the ice age because the dwarf bison were faster, reproduced more rapidly and required less vegetation to sustain them. The destruction of giant bison resembles what happened to the bison in modern day America; accept they had to survive droughts instead of extreme cold.
Several mass extinctions have occurred during the Earth’s history. The Cretaceous – Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it’s occurrence is abundant.
Snow leopard. When most people hear those words put together, they think of a large, stunning cat with piercing blue eyes, prowling across a snowy terrain high up in the mountains. What they don’t imagine is a helpless animal whose habitat is being destroyed. That is exactly what is happening to these beautiful creatures. Mountain ranges, where these rare cats live, are under the attack of global warming, and the snow leopard population is dwindling because of humans. One of the more well-known snow leopard habitats are the Himalayas. Located in Asia, the Himalayas are becoming warmer each year, which results in a higher treeline. The snow leopards are forced to retreat ever higher into the mountains, where there is less food, vegetation, and, most importantly, oxygen. Even more, humans are attracted to the alluring furs of this beautiful feline. Illegal hunters, or poachers, track down the snow leopards and kill them for their pelts, bones, and body parts. The snow leopard’s fur is a whitish-gray color, tinged with occasional yellow in the spring and dark gray to black splotches, or rosettes (Scherer & Fletcher). The colors of their fur act as camouflage against the mountain snow. Additionally, this cat is one of the smallest of the world’s large cats, averaging about two feet tall from paws to shoulders and about six feet from head to the base of the tail. The tail, however, can add up to three feet to their body length. The snow leopard eats anything from wild sheep to birds to gazelles to red pandas. It is obviously a meat eater, which is called a carnivore. Back to the point, snow leopards are in great danger of becoming extinct if humans continue to hunt them for their pelts and bones and if climate change co...
The white tiger is one of the biggest in the cat family. The white tiger is long it can grow up to 3.3 meters long and weigh as much as 300 kilograms hard to carry. Subspecies of the white tiger like Sumatran Tiger, Amur(or Siberian) Tiger, Indian (or Bengal) tiger, south china tiger, malayan tiger,indo-chinese tiger,bali tiger,javan tiger,caspian tiger thats extinct theres nine subspecies of the white tiger.A lot of subspecies are endangered or extinct because people hunt them for their fur to make jackets or sweaters and destroying their habitat.Some tiger cubs don’t live to be an adult because around half of the cubs die around 2-3 years of age.The cubs leave their mother at around 2 years old they live a long time because their mom taught them what they would know from eating to hiding from people.A group of tigers is called ambush or streak because the group may be hunting.You probably thought these tigers can’t swim because they are in the cat family but if you do you are wrong because ...
slow extinction, or did it happen all of the sudden? These questions bring rise to many
The Siberian tiger is a solitary animal, preferring to travel and hunt alone or with a small pack. This animal lives in mountainous regions and heavily forested areas.
Otherwise known as saiga tatarica originally lived in the Eurasian steppe. They also lived in North America. Today they are only found in Russia and Kazakhstan. Normally their height is 0.6 - 0.8 meters at the shoulder and weighs 36 - 63 kilograms (79- 139 Pounds). Their lifespan is 6 to 10 years. They are in Phylum: Chordata, Class: Mammalia, Family: Bovidae. They form large herds in grasslands, steppes, and semidesserts.
