### Instruction: What is the biggest land mammal?
### Response: The answer depends on how you measure size and whether you are talking about living animals or extinct animals.

The heaviest living land mammal is the African elephant at 7 tons. The tallest is the giraffe at 19 feet.

The largest extinct land mammal is not known for sure, and new fossils may be discovered at any time, but in 2021 palaeontologists claimed that a new species of giant rhino - Paraceratherium linxiaense - was likely the heaviest known at around 24 tons.
