Albertosaurus sarcophagus
Albertosaurus is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period, more than 70 million years ago. The type species, A. sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named. Scientists disagree on the content of the genus, with some recognizing Gorgosaurus libratus as a second species.As a tyrannosaurid, Albertosaurus was a bipedal predator with tiny, two-fingered hands and a massive head with dozens of large, sharp teeth. It may have been at the top of the food chain in its local ecosystem. Although relatively large for a theropod, Albertosaurus was much smaller than its more famous relative Tyrannosaurus, probably weighing less than 2 metric tons.

Yutyrannus huali
Yutyrannus (meaning "feathered tyrant") is a genus of tyrannosauroid theropod dinosaurs from the Early Cretaceous of China. Three specimens of Yutyrannus huali found in the fossil beds of Liaoning Province are currently the largest known dinosaur fossils that preserve direct evidence of feathers. Yutyrannus contains a single type species, Yutyrannus huali, named and described in 2012 by Xu Xing et al. The generic name is derived from Mandarin Chinese yu (羽, "feather") and Latinised Greek tyrannos (τύραννος, "tyrant"), a reference to the classification as a feathered member of the Tyrannosauroidea. The specific name consists of the Mandarin huáli (华丽, "beautiful"), in reference to the beauty of the plumage. Yutyrannus were gigantic bipedal predators. The holotype and oldest-known specimen has a length of 9 metres (30 ft) and an estimated weight of about 1,414 kg (3,120 lb). Its skull has an estimated length of 905 millimetres (35.6 in). The skulls of the paratypes are 80 centimetres (31 in) and 63 centimetres (25 in) long and their weights have been estimated at 596 kilograms (1,310 lb) and 493 kilograms (1,090 lb) respectively. The describers established some diagnostic traits of Yutyrannus, in which it differs from its direct relatives. The snout features a high midline crest, formed by the nasals and the premaxillae and which is covered by large pneumatic recesses. The postorbital has a small secondary process, jutting into the upper hind corner of the eye socket. The outer side of the main body of the postorbital is hollowed out. In the lower jaw, the external mandibular fenestra, the main opening in the outer side, is mainly located in the surangular.

Yutyrannus vs Dryptosaurus


I can't find the weight for Dryptosaurus or a good imagine. So how about this instead?

Both are close to the same size. If you're talking about those reports of them over 10 meters long. that's probably their max.

I'm talking about mass

Albertosaurus = ~2000 kg
Yutyrannus = 1414 kg

Albertosaurus definitely has the size advantage

Read the OP. It says Albertosaurus would've weighed less than 2 tons.

At the same size, i would say 50/50. Both are very similar, and since Yutyrannus is new species, there's not much info about it

yutyrannus seems both slightly smaller overall and a good deal lighter in built. I´d favour a less bulky theropod if it was the same weight, but here albertosaurus´ has a decent size advantage, and also a more massive jaw. yutyrannus on the other hand would have been more agile, and it had claws, but that´s not enough imo to make up for it´s smaller size.

Oh, what about 1700 kilograms? Albertosaurus still has the size advantage
Wikipedia article about Albertosaurus
 
Albertosaurus was smaller than some other tyrannosaurids, such as Tarbosaurus and Tyrannosaurus. Typical adults of Albertosaurus measured up to 9 metres (30 ft) long, while rare individuals of great age could grow to over 10 metres (33 ft) in length. Several independent mass estimates, obtained by different methods, suggest that an adult Albertosaurus weighed between 1.3 tonnes (1.4 short tons) and 1.7 tonnes (1.9 tons).

Really? Read this.

Some size advantage. rolleyes

Those might of not been fully grown, while the 1414 kg one was an adult.

Even if they were the same size, Albertosaurus would still win, it's more robust and can apply strength more easily, and Albertosaurus has stronger jaws, since Albertosaurus' jaws are more massive

Size advantage or parity, Albertosaurus has the advantage

How massive is an average Albertosaurus in your opinion anyway?

That's because only very few theropods reach full size.

Probably around 3,000 lbs or more. Same as Yutyrannus.
