Dinosaur size
There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur "Argentinosaurus huinculensis", which is the largest dinosaur known from uncontroversial evidence, estimated to have been and long. Some of the longest sauropods were those with exceptionally long, whip-like tails, such as the "Diplodocus hallorum" (formerly "Seismosaurus") and the 33- to 35-metre-long (108–115 ft) "Supersaurus". The tallest was the "Brachiosaurus".
Gojirasaurus
"Gojirasaurus" is one of the largest meat-eating dinosaurs known from the Triassic Period, almost the size of its relative, the large coelophysoid "Dilophosaurus". The size of its tibia was 469 mm, which was comparable to that of "Liliensternus" (409 mm) and "Dilophosaurus" (555 mm), suggesting that it was a large triassic dinosaur, estimated to be about 5.5 m (18 ft) long, which can be extrapolated to a weight of approximately 150–200 kg (330–440 lb). Carpenter (1997) pointed to features of the pelvis and ankle suggesting that this was an immature individual, and could therefore have grown to even a larger size in maturity. Specimen NMMNH P-4666, which consists of only a pubis, was referred to this genus by Hunt in 1994.
