- Albertosaurus is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period, about 70 million years ago. Typical Albertosaurus adults measured up to 9 meters long, while rare individuals of great age could grow to be over 10 meters long. Several independent mass estimates, obtained by different methods, suggest that an adult Albertosaurus weighed between 1.3 tonnes and 1.7 tonnes.

- Alioramus is a genus of tyrannosaurid theropod dinosaurs from the Late Cretaceous period of Asia about 70 million years ago. Adults was estimated at 5 to 6 meters in length when originally described by Sergei Kurzanov in 1976. Kurzanov, however, did not correct for lengthening of the skull by deformation during fossilization, which may indicate a shorter overall body length for this individual. If this specimen is a juvenile, then adult Alioramus would have reached greater lengths, but no confirmed adult specimens are known.

Giraffatitan, is a genus of sauropod dinosaur that lived during the late Jurassic Period. All size estimates for Giraffatitan are based on the specimen HMN SII, a sub-adult individual between 21.8 to 22.5 meters in length. Mass estimates are more problematic and historically have varied from as little as 15 tonnes to as much as 78 tonnes. These extreme estimates are now considered unlikely due to flawed methodologies. More recent estimates based on models reconstructed from bone volume measurements, which take into account the extensive, weight-reducing air sac systems present in sauropods, and estimated muscle mass, are in the range of 23–37 tonnes.

They lived during the Middle Jurassic period, 162 to 150 million years ago. Palaeontologist L. B.

The body mass has been estimated at 1 and 1.7 tonnes for the lengths 4.8 and 7 meters respectively.
