Ok so.... I just kinda wanted to defend the inclusion of sinraptor in an area they aren't supposed to be in. The Tiaojishan formation seems.. Kinda empty in terms of "big predators." So.. They decided to use sinraptor for the predator in that scene because 1: they lived during the same general timeframe. And 2: Idk sinraptor is well known! Its the most well known species in its family.
Plus! It made for a fun scene. (In my opinion) Still not accurate though.
I mean.. Look at this!
Shishugou Formation (sinraptor)
Tiaojishan formation (Anchiornis)
Idk
