In the modern fauna, theropods are represented by over 11,000 species of birds, which are a group of maniraptoran theropods within the clade Avialae.. Theropoda (/ θ ɪəˈr ɒ p ə d ə /; [2] from ancient Greek θηρίο-ποδός [θηρίον, (therion) "wild beast"; πούς, ποδός (pous, podos) "foot"]), commonly known as theropods, is an extant dinosaur clade that is ...
This is a list of the mammal species recorded in Canada.There are approximately 200 mammal species in Canada. [1] Its large territorial size consist of fifteen terrestrial and five marine ecozones, ranging from oceanic coasts, to mountains to plains to urban housing, mean that Canada can harbour a great variety of species, including nearly half of the known cetaceans.

Specimens of Torvosaurus gurneyi were measured up to 10 meters (33 ft) in length and 4–5 metric tons (4.4–5.5 short tons) in body mass, [2] suggesting that it was much larger than T. tanneri and was the largest terrestrial carnivore in Europe during the Late Jurassic.
The ossified feet and exceedingly long tail of Aerosaurus suggests an agile terrestrial carnivore [2] ‘Pelycosaurs’ represent first group to dominate the terrestrial fauna and achieve large body size at a time where the supercontinent Pangea existed.
Except for an extraordinarily large specimen of A. angustidens, the largest specimens of A. simus and A. angustidens are said to be comparable to one another, [11] [12] and match the absolute upper size limit (~1000kg) of a terrestrial carnivore (based on the more restrictive energy base for a carnivorous diet). [13] [14] [15]
The fauna of Canada consist of approximately 200 mammal species, over 460 native bird species, 43 amphibian species, 43 reptile species, and 1,200 fish species. [ 1 ] [ 2 ] The biology survey of Canada cites that there are approximately 55,000 species of insects and 11,000 species of mites and spiders.
"Creodonta" was coined by Edward Drinker Cope in 1875. [1] Cope included the oxyaenids and the viverravid Didymictis but omitted the Hyaenodontidae.In 1880. he expanded the term to include families Miacidae (including Viverravidae), Arctocyonidae, Leptictidae (now Pseudorhyncocyonidae), Oxyaenidae, Ambloctonidae and Mesonychidae.
