Animalia Chordata Dinosauria Theropoda

Theropoda (Marsh, 1881) or theropods are bipedal, usually carnivorous dinosaurs. They are closer to birds than other dinosaur orders.


  • Carcharodontosauridae (theropods with long, narrow skulls, large orbits, three-fingered hands, and often "horns" or ornamental crests on their heads)


  • Abelisauridae (theropods with small vestigial arms and prominent head or skull ornamentation)

Maniraptoriformes (theropods with branching, bird-like feathers)

  • Alvarezsauridae (long-legged feathered dinosaurs with long beak-like snouts and tiny arms bearing an enlarged first claw)
  • Atroxignidae (feathered wyvern-like theropods with horned heads and spiky tails)
  • Dromaeosauridae (avian theropods that usually posses a large claw on the second toe of the hind foot)
  • Enantiornithes (extremely bird-like theropods which are capable of flight and have short or nonexistent tails)
  • Incisivosauridae (herbivorous maniraptors with somewhat short tails and rodent-like teeth)
  • Ornithomimidae (typically omnivorous ostrich- or emu-like theropods with toothless beaks, scaly or naked areas on their legs and underside, and soft feathers unsuitable for aerodynamic use)
  • Oviraptoridae (bird-like theropods with feathered wing-like arms, beaks, and, in some species, elaborate crests on their heads)
  • Scansoriopterygidae (paravian theropods with membrane wings formed by three fingers and an elongated wrist bone, superficially resembling those of a bat)
  • Sicklesauridae (scaly, often completely unfeathered raptor-like theropods)
  • Therizinosauridae (typically herbivorous theropods with relatively short tails, pot bellies, and huge claws)
  • Troodontidae (intelligent bird-like theropods resembling gracile raptors with smaller claws and more flexible tails)
  • Zexakidae (mostly scaly theropods with feathered tails, no wings, four-fingered hand(s), and venom glands on their necks)


  • Spinosauridae (sometimes quadrupedal piscivorous theropods with elongated crocodilian snouts and a sail or hump on their back)

Pterygiosauroidea (fictional theropods with fins or fin-like frills and skin flaps, especially on their faces, limbs, and tail)

  • Latroidae (scaly, lightly armored theropods with skin flaps on their arms and tails used for thermoregulation or photosynthesis)
  • Polylopimidae (theropods with distinctively finned faces)
  • Yapnepidae (long-legged finned theropods with hornlets on their faces)

Therioraptora (feathered dinosaurs with distinctly mammalian traits, specifically in the form of ears, which strongly deviate from other dinosaur groups)

  • Tateelotheriidae (therioraptors with long necks and long ears located near the back of their heads)
  • Therioraptoridae (therian-eared horned theropods with feathers and sickle- or talon-clawed, often paw-like feet)

Tyrannosauroidea (theropods with blunted snouts, long hindlimbs in comparison to their body and, usually, protofeathers partially covering their bodies)

  • Tyrannosauridae (theropods with large heads filled with bone crushing teeth, muscular legs and strong, though small, arms bearing two digits)

Unsorted Theropods

  • Blancamata (bipedal theropods with hardly any visible features)
  • Compsognathidae (small theropods with simple fur-like feathers covering their bodies)
  • Corsetidae (generally short-tailed theropods covered in thorns)
  • Herrerasauridae (early theropod-like dinosaurs with primitive traits, such as five or more digits in hands and/or feet, and narrow dromaeosaur-esque skulls)
  • Kicathidae (armoured humanoid theropods)
  • Mytimallidae (armless theropods with skinny tails and extended tube-shaped nostrils)

Other Theropods

  • Aves (birds and bird-like creatures)
