Size of three Yutyrannus specimens compared to a human. Yutyrannus was a large bipedal predator. The holotype and oldest-known specimen has an estimated length of 9 metres (29.5 ft) and an estimated weight of about 1,414 kilograms (3,117 lb). [1] In 2016, Gregory S. Paul gave lower estimations of 7.5 metres (24.6 ft) and 1.1 tonnes (1.2 short ...

The animals reach a body length of 7 to 10.5 millimeters (females) and 6 to 8.5 millimeters (males). Their body is black-yellow colored, which is rare within the genus. Melanistic forms also occur. The terminal ridge on the edge of the occipital crest has a tooth-like projection underneath.
Tsaagan is a member of the group Dromaeosauridae.A cladistic analysis by Norell et al. originally indicated it was more precisely a member of the Velociraptorinae. [1] In 2010 an analysis showed it was closely related to Linheraptor; [3] subsequently Senter (2011) and Turner, Makovicky and Norell (2012) argued that Linheraptor exquisitus is in fact a junior synonym of Tsaagan mangas.

Kansaignathus is a small-bodied dromaeosaur which was probably similar in size to Velociraptor.The authors of its description estimate that it was probably about 2 metres (6.6 ft) long, [2] which is similar to seize estimates for Velociraptor [5] and Dineobellator.
Xenosmilus is in the tribe Homotherini in the subfamily Machairodontinae of the cat family. [1] A paper published in 2022 proposed that Xenosmilus is a more derived member of the tribe Machairodontini (another name for Homotherini), and that Homotherium venezuelensis should be reassigned to Xenosmilus, [11] with a 2024 paper arguing that remains from Uruguay should also be assigned to the ...
