In decades long past, some reached lengths of 20 feet and lived more than 100 years.
Scutellosaurus reached lengths of 1.5 to 2 metres (about 5 to 6.5 feet).
Massively built and large for their day, they reached lengths of 2 to 3 metres (about 7 to 10 feet).
Two members of the group, Diplodocus and Supersaurus, may have reached lengths of up to 34 metres (112 ft).
The fabrosaurs were the earliest and most primitive of the ornithopods; these small, lightly built dinosaurs reached lengths of 60 120 cm (2 4 feet).
Hadrosaurs commonly reached lengths of 9 11 metres and were among the most abundant dinosaurs in North America by the end of the Cretaceous Period.
The lengths of the GaN NWs grown under 100% H2 reached lengths >10 μm as shown in Figure 1b and Table 1.
Fragmentary remains of larger individuals indicate that some adults reached lengths of more than 8 m.
The adult snake's length ranges from 2 m to 3 m routinely but, according to some sources, specimens have reached lengths of 4.3-4.5 4.3-4.5
Some of the bridges reached lengths of 1220 m, with many being wide enough to allow two lanes of cart traffic simultaneously over a waterway or ravine.
Albertosaurus, Gorgosaurus and Daspletosaurus all measured between 8 and long, while Tarbosaurus reached lengths of 12 m from snout to tail.
