Yun & Carr, 2020
Stokesosauridae is a suggested family of small to medium-sized tyrannosauroid theropods whose fossil remains have been found in North America and Europe. It includes the genera Stokesosaurus, and Juratyrant, and it may also include Eotyrannus.The family name first appeared in the supplemental info of Carr et al. (2017) and was first used within the main text of a paper during Wu et al. (2019)'s description of Jinbeisaurus, although no formal ICZN recognition was provided at the time. The family was formally named shortly afterwards by Yun & Carr (2020). The constituents of Stokesosauridae had been considered closely related to each other for several years prior. A sister-taxon relationship between Stokesosaurus and Juratyrant has been found by every major tyrannosauroid study ever since the latter was described as a species of the former in 2008. Eotyrannus has also been associated with these taxa in many tyrannosauroid studies, the first of which being Brusatte & Carr (2016). In addition there is a possibility which the genera Aviatyrannis and Tanycolagreus might be members of this family as well.
