プラティベロドンを追うメガロドン(01 of19)
Open Image ModalThe Miocene epoch (23.03 to 5.332 million years ago) boasted a real life sea monster, Carcharocles megalodon. Whereas the giant shark mainly inhabited the open ocean, this image depicts a hypothetical encounter with a swimming Platybelodon, a prehistoric mammal related to the elephant. The bones of these elephantids sometimes show evidence of attack by sharks.\n (credit:Julius Csotonyi)

ドルドン(06 of19)
Open Image ModalThere was a time early in cetacean evolution when ancient whales possessed external hind limbs, a telltale sign of their terrestrial evolutionary heritage. Dorudon was a good example. (credit:Julius Csotonyi)
パルム紀の自然(07 of19)
Open Image ModalThis image depicts the bizarre interval in Earth’s history when insects such as Meganeuropsis (a gigantic prehistoric griffinfly) outgrew reptiles such as Hylonomus. Swamps teemed with crocodile-like amphibians such as Eryops. (credit:Julius Csotonyi)
川沿いの死闘(08 of19)
Open Image ModalAs paleontologists have elucidated, some pterosaurs (flying reptiles) were enormous – as tall as giraffes even. In this image, the pterosaur Quetzalcoatlus dwarfs Tyrannosaurus (left), while another T. rex squares off with a Triceratops during the Late Maastrichtian age (72.1 to 66 million years ago).

Open Image ModalThis image reenacts a moment in the last few hours of life of a pack of Utahraptor (a theropod dino) and the Hippodraco (an iguanodontian dino) that lured them to their miry fate in a patch of Early Cretaceous Utah quicksand. (credit:Julius Csotonyi)

連携して獲物を追いかける恐竜(19 of19)
Open Image ModalAround 33.9 million to 23 million years ago, the Oligocene epoch was ruled by giant rhinos, fierce mammalian predators called hyaenodontids (left), oreodonts (extinct hoglike animals) and the near-cat saber-toothed nimravids (right). Toothy pig-like omnivores called entelodonts (e.g. Archaeotherium) may have hunted diminutive early horses (e.g. Mesohippus) (center). (credit:Julius Csotonyi)
