Sinosauropteryx
"Sinosauropteryx" was a small bipedal theropod, noted for its short arms, large first finger (thumbs), and long tail. The taxon includes some of the smallest known adult non-avian theropod specimens, with the holotype specimen measuring only in length, including the tail. However, this individual was relatively young. The longest known specimen reaches up to in length, with an estimated weight of .
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.
