Metriacanthosaurids were the first group of allosauroids to appear. They were large predators. The family was until recently called "Sinraptoridae", but this was a junior synonym (later-given name) and so lost priority when scrutiny was applied.
- Siamotyrannus isanensis (placement uncertain)
- Shidaisaurus jinae (may be too basal)
- Sinraptor/S. dongi/ S. hepingensis (?)
- Xuanhanosaurus qilixiaensis (may be megalosauroid)
