Saber Tooth Tiger Facts For Kids

1. What is a Saber Tooth Tiger

  • In short, Saber Tooth Tiger is prehistoric carnivorous mammal, with distinctive pair of long razor sharp canine teeth, that got extinct at the end of the Ice Age some 10,000 years ago.
  • It is very popular among the prehistoric animals due to its fascinating looks and its elongated sword shaped canine teeth.
  • It was found in North and South America.
  • It existed between the Eocene and the Pleistocene period which ranges from 55 million years to 10,000 years ago.
  • It was the primary predator in the woodlands and grasslands.
  • Previous studies of fossils suggests that it became extinct mainly due to lack of food which was caused by the climate change. Climate change caused plants extinction which resulted in extinction of herbivores (animals that eat plants) and ultimately it caused Saber Tooth Tiger extinction as there were no more herbivores to hunt for food.
  • Recent studies on fossils deny the above reason of extinction but do not provide any new theory on saber tooth tiger extinction.
  • The Saber Tooth Tiger is also called the saber-toothed lion or saber toothed cats but in reality it is not a tiger or a lion or even close to the cats that we have today. It belongs to an extinct sub-family of  the cat family (Felidae) which is called Nimravidae or the subfamily Machairodontinae.

2. Scientific Name for Saber Tooth Tiger

  • The scientific name for Saber Tooth Tiger  is “Smilodon” which means tooth like a double edge knife.

3. Saber Tooth Tiger Classification

Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Felidae
Subfamily: Machairodontinae
Tribe: Smilodontini
Genus: Smilodon

4. Saber Tooth Tiger Description 

  • The Saber Tooth Tiger has been named after its long and sharp Canines.
  • Its two long canines could grow up to 20 cm or 8 inches, which helped in cutting and stabbing its preys.
  • The lower canines were smaller in size and the molar teeth were smooth and resembled the modern day shearing blades.
  • Its jaw could open up to an angle of 90 degrees in order to use the long teeth for hunting purposes. This gape is much larger than the modern cats.
  • Its neck had strong muscles to bring down the heads of large preys.
  • Its limbs were short but very well developed for hunting.
  • The fully grown Saber Tooth Tiger size was about that of a modern day African Lion (Panthera Leo).
  • The smallest species, S. gracilis found in North America weighed 55 to 100 kg. And the largest species from South America, S. populator weighed 220 to 400 kg.
  • The coat color pattern of the Saber Tooth Tiger is yet unknown.

5. Saber Tooth Tiger Characteristics

  • The body length of the Saber Tooth Tiger was 175 cm from nose to the rump.
  • The height of its shoulders was up to 100 cm.
  • Its tail grew up to a length of 35 cm.
  • It had large head with two long canine teeth in the upper jaw. These teeth could grow up to be 20 cm long.
  • The canines grew up to their full size three years after birth.
  • Physically, the Saber Tooth Tiger was similar to the modern Lion in size, but it was more robust with shorter limbs.
  • The weights of different species of the Saber Tooth Tiger ranged from 55 to 400 kg. Which means it was the largest cat to live on earth.
  • The running of speed of the Saber Tooth Tiger is not accurately known. However, as it was a heavy cat, so it was slower than the Lion and Tiger. Its top speed was about 25 to 30 mph.
  • The average lifespan of a Saber Tooth Tiger is unknown.

6. Where did the Saber Tooth Tiger live

  • The Saber Tooth Tiger lived in North America and Europe during the Miocene and Pliocene Epoch (23 million to 2.6 million years ago).
  • They spread to Asia and Africa after Pliocene Epoch.
  • Some Saber Tooth Tigers moved to South America during the Pleistocene Epoch (2.5 million to 10,000 years ago).

7. Saber Tooth Tiger Habitat

  • The Saber Tooth Tiger lived in areas where plant-eating animals lived.
  • These areas include pine forests, shrubby areas and grasslands.

8. Saber Tooth Tiger Diet

  • The Saber Tooth Tiger was a carnivore (meat-eater).
  • It ate any meat it could find. But it mostly hunted herbivores (grass-eaters).

9. Saber Tooth Tiger Prey

  • Mostly, the Saber Tooth Tiger hunted herbivores.
  • It might have hunted Horses, Bison and Mastodons (extinct hairy elephants).

10. Saber Tooth Tiger Timeline

  • Three different species of the Saber Tooth Tiger existed between 2.5 millions and 10,000 years ago.

11. Smilodon Species – Saber Tooth Tiger Species

  • The Saber Tooth Tiger has three species:
    1. Smilodon fatalis
    2. Smilodon gracilis
    3. Smilodon populator
  • S. gracilies was the smallest among the species, while S. populator was the largest.
  • The main difference between these species was weight and size.

12. Saber Tooth Tiger Size – Saber Tooth Cat Size – Smilodon Size

  • Different species of the Saber Tooth Tiger came in different sizes.
  • Following are the different species with their weights and sizes from smallest to largest:




S. gracilis

55 to 100 kg


S. fatalis

160 to 280 kg

100 cm

S. populator

220 to 400 kg

120 cm

13. Saber Tooth Tiger Size Comparison – How Big was a Saber Tooth Tiger

  • The Saber Tooth Tiger was the size of modern African Lion (Panthera Leo) and Tiger. However, the Smilodon had a stronger build than the modern cats.
  • Compared to humans, the Saber Tooth Tiger had more weight but was shorter in height.

14. How do Saber Tooth Tigers Hunt

  • Saber Tooth Tigers hunted in packs like modern lions.
  • However, the Saber Tooth Tiger had different killing techniques than modern cats.
  • It used to wrestle large preys to the ground by using its claws and forelimbs, then ripped open its throat using the large canines in order to kill it instantly.
  • It could only hunt large herbivores because it didn’t have the agility to chase small animals like deer and antelope. So, it preferred ambushing its prey.

15. Saber Tooth Tiger Behavior

  • The Saber tooth tiger lived and hunted in packs. This ensured that they had food even when they were ill, injured or old. Other members of the pack used to share food with the affected member.
  • Just like modern lions, the saber tooth tigers hunted animals in group by trapping them.
  • There were no visible differences in behavior and appearance in between the male and female saber tooth tigers.

16. Inter-species Interaction

  • Smilodon was the top predator in its habitat.
  • The availability of prey was equal to or greater than the prey availability today in East Africa.
  • Near the end of the Pleistocene Epoch, Smilodon and other carnivores often broke their teeth indicating intense competition in hunting and eating the preys all the way to their bones.
  • As the Smilodon couldn’t crush bone, they could have associated with bone-crushing hyenas.

17. Saber Tooth Tiger Adaptations

  • The Saber Tooth Tiger had a bob-tail which suggests that it used to ambush its its prey instead of chasing it like modern Lions and Tigers.
  • It had 20 cm long canine teeth which had a oval cross-section which could be used as knives. They were useful for slicing meat but also fragile. They could easily break while hunting. They could also be used for social display as horns.
  • Its killing behavior determines that its bite wasn’t as strong as a modern lion. That is why they wrestled the prey to ground before delivering the killing bite with their sharp canines. However, it is unknown how the finishing bite was delivered.
  • About social behavior, it has been discovered that the Saber Tooth Tiger was a social animal and used to hunt in packs. Fossils have shown evidence of regrowth and healing, which suggests they lived for a long time after getting injured. Other members of the pack brought food for the injured Smilodon. However, it has been discovered they were also not very peaceful. Sometimes, they fought among themselves for food or mates like modern lions.

18. Saber Tooth Tiger Extinction

The Saber Tooth Tiger went extinct at the end of the Pleistocene Epoch (12,000 years ago). The exact cause of their extinction has not be determined precisely and there are two different theories explaining different reasons for their extinction.

  • Some researchers suggest that the root cause of the extinction of the Smilodon is lack of prey. After the large herbivores went extinct at the end of the Ice Age, the Saber Tooth Tiger also went extinct due to unavailability of food.
  • Other researchers suggest that the Saber Tooth Tiger had decent amount of food available to live. However, they went extinct as a result of humans hunting them, damaging their habitat or climate change.

20. Saber Tooth Tiger Facts Summary



  1. This is excellent. I knew that there were several species of Smilodon and we have S. gracilis here. Wanted to know what the relative sizes of them were and found in addition to the relative size of other big cats and other Smilodon, S. gracilis is shorter than but heavier than an African lion.

  2. These extinct animals fascinate me. And it hasn’t been all that long since they disappeared off the planet. I remember seeing a skull of a human from the Pleistocene that had a gouge near the top of its skull that perfectly matched a sable tooth’s long canine. Looks like the poor human was pounced on from above by one of these guys that might have been waiting in ambush.
