Description
Size comparison of large animals that lived between 70 million years ago and 13 years ago.
Upper row: Eurotamandua (primitive, anteater-like pangolin), Asiatosuchus grangeri (large terrestrial crocodile), Prorastomus sirenoides (early, amphibious sirenian), Ptilodus montanus (rodent-like mulitituberculate), Ankalagon saurognathus (large, hoofed carnivore), Juxia sharamurenense (hornless, maned rhinoceros), Icadyptes salasi (long-beaked penguin), Indohyus indirae (small herbivore ancestral to whales), Patriofelis ferox (cat-like, short-legged creodont), Baryphracta deponiae (small, European alligator), Hyracodon nebraskensis (gracile herbivore related to rhinos), Archaeotherium mortoni (long-jawed, predatory pig), Titanoboa cerrejonensis (gigantic constrictor snake) and Phiomia serridens (one of the first large proboscideans).
Middle row: Bathyopsis fissidens (long-fanged, rhino-like herbivore), Coryphodon eocaenus (one of the first large herbivores), Scarrittia canquelensis (South American hoofed mammal ancestral to Toxodon), Cladosictis (otter-like carnivore related to modern marsupials), Mesohippus montanensis (primitive horse), Phosphatherium escuillei (small, early proboscidean), Paraphysornis brasiliensis (large terror bird), Prodinoceras (ancestor of Dinocerata, fanged, rhino-like mammals), Homalodotherium (strange, clawed herbivore from South America), Rhynchippus equinus (small, South American herbivore), Trogosus castoridens (primitive herbivore with rodent-like teeth), Stylinodon mirus (large-snouted omnivore), Chenanisuchus lateroculi (crocodylomorph, that survived Cretaceous-Tertiary extinction) and Trigonias osborni (early rhinoceras).
Lower row: Barylambda churchilli (large, bear-like herbivore), Embolotherium andrewsi (massive, rhino-like beast related to modern horses), Arcotcyon primaevus (primitive, dog-like omnivore, possibly a climber), Trigonostylops (early, tapir-like mammal), Psilopterus bachmani (small terror bird), Borhyaena (massive carnivore related to modern marsupials), Thomashuxleya rostrata (pig-like Toxodontid), Phosphatosaurus gavialoides (huge, gavial-like crocodylomorph), Palaeomastodon (primitive proboscidean, one of the first to posses a trunk), Eremopezus eocaenus (large, enigmatic, possibly flightless bird), Eusmilus cerebralis (fales sbre-toothed cat) and Kopidodon macrognathus (primitive, squirrel-like mammal).
