If you glance to the right (or above, if you're on our mobile site), you will notice a top ten list of the longest dinosaurs, plucked from our prehistoric database.
The list will be automagically updated as longer species are discovered.
Please bear in mind that all extinct dinosaur sizes are based on often shabby remains using the not strictly scientific method of "guestimation".
Seldom will a complete skeleton be discovered, so scientists sometimes upscale using parts from a similar dinosaur as reference. It ain't foolproof.
