Tarbosaurus bataar Tarbosaurus belongs in the subfamily Tyrannosaurinae within the family Tyrannosauridae, along with the earlier Daspletosaurus, the more recent Tyrannosaurus and possibly Alioramus. Animals in this subfamily are more closely related to Tyrannosaurus than to Albertosaurus and are known for their robust build with proportionally larger skulls and longer femurs than in the other subfamily, the Albertosaurinae. Although many specimens of this genus have been found, little definite data was confirmed on the dinosaur as of 1986, though it was presumed to share many characteristics with other tyrannosaurids. The close similarities have prompted some scientists to suggest a possible link between the North American and Eurasian continents at that time, perhaps in the form of a land bridge. As with most dinosaurs, Tarbosaurus size estimates have varied through recent years. It could have been 10 meters long, with a weight of 4 to 5 - 7 tons. ![]() Therizinosaurus cheloniformis Therizinosaurus (play /θɛˌrɪzɨnɵˈsɔrəs/; 'scythe lizard', from the Greek therizo meaning 'to reap' or 'to cut off' and sauros meaning 'lizard') is a genus of very large theropod dinosaur. Therizinosaurus lived in the late Cretaceous Period (late Campanian-early Maastrichtian stages, around 70 million years ago), and was one of the last and largest representatives of its unique group, the Therizinosauria. Its fossils were first discovered in Mongolia and they were originally thought to belong to a turtle-like reptile (hence the species name, T. cheloniformis — "turtle-formed"). It is known only from a few bones, including gigantic hand claws, from which it gets its name. Though the fossil remains of Therizinosaurus are incomplete, inferences can be made about its physical characteristics based on related therizinosaurids. Like other members of its family, Therizinosaurus probably had a small skull atop a long neck, and had a bipedal gait and a heavy, deep, broad body (as evidenced by the wide pelvis of other therizinosaurids). Its forelimbs may have reached a length of 2.5 metres (8 feet) or even 3.5 metres for the largest known specimen. Its hindlimbs ended in four weight-bearing toes, unlike other theropod groups, in which the first toe was reduced to a dewclaw. Gregory S. Paul in 2010 estimated the length of Therizinosaurus at ten metres, the weight at five tonnes. It is the largest therizinosaur known and the largest known member of the Maniraptora. The most distinctive feature of Therizinosaurus was the presence of three gigantic claws on each digit of its frontlimbs. These were common among therizinosaurs but especially large in Therizinosaurus, and while the largest claw specimens are incomplete, they probably reached just under 1 metre (3.28 ft) in length. The claws are the longest known from any animal. The claws were relatively straight, only gradually tapering into a point, and extremely narrow, transversely flattened. ![]() _________________________________________________________________________

That Therizinosaurus seems to be scaled too small compared to the T. rex, and Tarbosaurus is smaller than Tyrannosaurus. Rexy is over 12m in standing lenght and 12.6m in axial lenght in that scale (too large even for sue), the Therizinosaurus is 8.65m in axial lenght (should be ~10m for the biggest specimen) |

Seing as broly scaled MOR 008 to around to 12.6 metres it doesn't seem too far fetched. Also I had a feeling Therizinosaurus was too small. But I didn't make the comparison its for a sense of scale compared to a larger animal. |

Well, broly got to that conclusion based on AMNH 5027. He explicitely noted the resulting animal wouldn’t be bigger than sue in terms of mass, but the reconstruction you have in there is very bulky, as in "suish". Not the point of discussion however. It’s just that the Therizinosaurus is scaled too small relative to the T. rex, and that that will certainly not give you a realistic demonstration on how the two animals relevant here would look compared to each other. |

Therizino has a slight edge here, seeing its large claws can act as a major barrier. |

Therizinosaurus's claws were very heavy, making them hard to swing effectively. They were also brittle. The claws were likely more of a threat display than an effective weapon. |
