>The third metatarsal of tyrannosaurids, including in the very largest forms, was pinched at the top between the second and fourth, forming a structure known as the arctometatarsus that aided in energy conservation and, in smaller forms, increased speed.[1] The arctometatarsus was also present in Appalachiosaurus[8] but it is unclear whether it was found in Eotyrannus[5] or Dryptosaurus.[16] This structure was shared by derived ornithomimids, troodontids and caenagnathids,[17] but was not present in basal tyrannosauroids like Dilong paradoxus, indicating convergent evolution.[2]
Can somebody explain to me like I'm brain dead why "tyrannosauroidea" is a valid clade and why we know all of its members were even coelurosaurs?

Apparently they found a leopard seal tooth from a Pleistocene age site alongside the normal African wildlife and I don't think you could mistake these for anything else

It ain't. Tyrannosaurids being coelurosaurs is pure chinktroon propaganda trying to force feathers on T. rex.

Proceratosaurids, including Dilong,Tanylogreus (and presumably also Yutyrannus, the potential sister taxon of and nearly identical to the unambiguous proceratosaurid Sinotyrannus, included), are early-diverging maniraptoromorphs outside Tyrannosauroidea and eutyrannosaurs are consistently paired with Megaraptora, Labocania and formerly thought as "unambiguous derived carcharodontosaurids" like Shaochilong.
