>>5117591>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?
