In context
Worked out from the sourced figure above, which stays the ranked number.
This list
A mammal is fast when its legs, lungs and muscles can keep a stride going. Most of the speeds on this list are compiled estimates, not a fresh stopwatch trial.
Speed here is how fast the limbs can cycle and how much ground each cycle covers. A longer leg helps only if the animal can still swing it quickly.
Garland's 1983 review gathered older reports and marked how each one was made. A timed run and a field estimate are not the same kind of evidence, which is why the cheetah's ranked figure is a separate trial.
The timed exception on this list is the cheetah.
This is how the category works. A note written for this entry appears here once it is in the database.
Provenance
Claimed, measured and official figures side by side, each with its source. The ranked figure is marked.
