19 crazy critters from the cretaceous

<i>Concavenator corcovatus</i>, the Spanish sensation had a strange hump on its back, the function of which is unknown. Fossils also show evidence of quilled feathers on its arms, although that claim has been disputed. This medium sized Spanish theropod is known from a single relatively complete skeleton. (Nobu Tamura)

<i>Cryolophosaurus ellioti</i> has been informally named "Elvisaurus" because of a crest that resembles the haircut of the King. It is the first theropod found on the continent of Antarctica. (Nobu Tamuar)

<i>Carbonemys </i>was a large side-necked turtle that could reach a length of 2m. It had a powerful bite sufficient to crush young crocodiles. (Nobu Tamura)

Microraptor zhaoianus, a four-winged dinosaur, was shown to prey on birds. (Nobu Tamura)

<i>Dryptosaurus aquilunguis</i> is known from very fragmentary remains. There are however enough of them to be able to classify it as a tyrannosaurid of some sort. <i>Aiilunguis</i> also means "eagled clawed." (Nobu Tamura)

<i>Falcatus falcatus,</i> an odd looking shark. (Nobu Tamura)

<i>Kronosaurus queenslandicus</i>, a giant marine reptile from Australia. (Nobu Tamura)

<i>Spinosaurus</i>, a fish-eating dinosaur. (Nobu Tamura)

<i>Tianyulong confuciusi</i> is is a small ornithischian dinosaur. Well-preserved fossil show traces of filamentous feather-like structures on the back, tail and neck of the fuzzy animal. (Nobu Tamura)

<i>Aegyptocetus tarfa</i>, an ancestor of the whale is attacked by a shark. (Nobu Tamura)

<i>Tyrannosaurus rex</i>, the famed moviestar dino has been slightly modified in light of new studies. Its skull appears to be narrower than previously thought, while its tail is beefier. We also now know it had feathers. (Nobu Tamura)

<i>Ctenoimbricata spinosa</i>, the sea urchin's great great great grandfather. (Nobu Tamura)

<i>Europejara olcadesorum</i>, the toucan flying reptile. (Nobu Tamura)

<i>Gerobatrachus hottoni</i>, an ancestor of the frog. (Nobu Tamura)

Futalognkosaurus dukei, a titanosaur that was one of the largest land creature that has ever lived with a size estimate rivaling <i>Argentinosaurus</i>. It is also one of the most complete titanosaur known with a combined 70% of the skeleton found from three individuals. (Nobu Tamura)

<i>Gigantspinosaurus sichuanensis</i>, a medium sized stegosaur is characterized by its extremely large shoulder spines. It might be the most primitive stegosaur known to date. (Nobu Tamura)

<i>Jeholornis palmapenis</i> (really?), a large primitive bird with a tail with feathers arranged like a palm tree. (Nobu Tamura)

<i>Nyctosaurus gracilis</i>, an extraordinary pterosaur with an unusually large and elaborate cranial crest on top of its head. It is also the only pterosaur to have lost its clawed fingers, indicating that it must have spent the majority of its time in flight. The exact function of the crest is unknown but it is likely that it was used for display. The antler-like crest only appears on the new two specimens described by Bennett (2003), previous specimens being either crestless or with the crest not preserved, indicating a possible sexual dimorphism. (Nobu Tamura)

<i>Sauropelta edwardsorum</i>, a small armored nodosaur with long spines projecting from its neck. (Nobu Tamura)
