How heavy were saber-toothed tigers?

Saber-toothed tigers, or more accurately, Smilodon, varied in size, with the most common species, Smilodon fatalis, being the largest. Here's a breakdown:

* Smilodon fatalis: Estimated to weigh between 220 and 400 kg (485-882 lbs). This makes them comparable in size to modern lions or even larger.

* Smilodon gracilis: A smaller species, weighing around 50-100 kg (110-220 lbs).

* Smilodon populator: This South American species was the largest, with some estimates placing its weight up to 470 kg (1,036 lbs).

So, the weight of a saber-toothed tiger could range from the size of a large dog to the size of a modern lion.
