Dosahoval délky zhruba 8,5 metru a hmotnosti kolem 2000 kilogramů. (cs) Ichthyovenator is a genus of spinosaurid dinosaur that lived in what is now Laos, sometime between 125 and 113 million years ago, during the Aptian stage of the Early Cretaceous period. It is known from fossils collected from the Grès supérieurs Formation of the , the first of which were found in 2010, consisting of a partial skeleton without the skull or limbs. This specimen became the holotype of the new genus and species Ichthyovenator laosensis, and was described by palaeontologist Ronan Allain and colleagues in 2012. The generic name, meaning "fish hunter", refers to its assumed piscivorous lifestyle, while the specific name alludes to the country of Laos. In 2014, it was announced that more remains from the dig site had been recovered; these fossils included teeth, more vertebrae (backbones) and a pubic bone from the same individual. The holotype specimen is estimated to have been between 8.5 to 10.5 metres (28 to 34 feet) long and to have weighed 2.4 tonnes (2.6 short tons; 2.4 long tons). Ichthyovenator's teeth were straight and conical, and its neck resembled that of the closely related genus Sigilmassasaurus. Like others in its family, Ichthyovenator had tall neural spines that formed a sail on its back. Unlike other known spinosaurids, Ichthyovenator's sail had a sinusoidal (wave-like) shape that curved downwards over the hips and divided into two separate sails. The pelvic girdle was reduced; the ilium—the uppermost body of the pelvis—was proportionately longer than both the pubis and ischium than in other known theropod dinosaurs. Ichthyovenator was initially thought to belong to the subfamily Baryonychinae but more recent analyses place it as a primitive member of the Spinosaurinae. As a spinosaur, Ichthyovenator would have had a long, shallow snout and robust forelimbs. Its diet likely mainly consisted of aquatic prey, hence its etymology. Spinosaurids are also known to have eaten small dinosaurs and pterosaurs in addition to fish. Ichthyovenator's conspicuous sail might have been used for sexual display or species recognition. Fossil evidence suggests spinosaurids, especially spinosaurines, were adapted for semiaquatic lifestyles. The vertebral spines of Ichthyovenator's tail were unusually tall, suggesting—as in today's crocodilians—the tail may have aided in swimming. Ichthyovenator lived alongside sauropod and ornithopod dinosaurs, as well as bivalves, fish and turtles.

A espécie-tipo é denominada Ichthyovenator laosensis. Seus restos fósseis foram encontrados na Formação Grès supérieurs, província de Savannakhet, Laos e data do Cretáceo Inferior, mais precisamente do estágio Albiano. A amostra do holótipo é estimada em ter entre 8,5 a 10,5 metros de comprimento e pesar 2,4 toneladas. Os dentes do Ichthyovenator eram retos e cônicos, e seu pescoço lembrava o do gênero Sigilmassasaurus intimamente relacionado. Como outros em sua família, o Ichthyovenator tinha espinhos neurais altos que formavam uma vela em suas costas. Ao contrário de outros espinossaurídeos conhecidos, a vela do Ichthyovenator tinha uma forma sinusoidal (em forma de onda) que se curvava para baixo sobre os quadris e se dividia em duas velas separadas. A cintura pélvica foi reduzida; o ílio - a parte superior do corpo da pelve - era proporcionalmente mais longo que o púbis e o ísquio do que em outros dinossauros terópodes conhecidos. Ichthyovenator foi inicialmente pensado para pertencer à subfamília Baryonychinae, mas análises mais recentes colocam-no como um membro primitivo dos Spinosaurinae. Como um espinossauro, Ichthyovenator teria um focinho longo e raso e membros anteriores robustos. Sua dieta provavelmente consistia principalmente de presas aquáticas, daí sua etimologia. Os espinossaurídeos também são conhecidos por terem comido pequenos dinossauros e pterossauros, além de peixes. A vela conspícua de Ichthyovenator pode ter sido usada para cortejo sexual ou reconhecimento de espécies. Evidências fósseis sugerem que os espinossaurídeos, especialmente os espinossaurinos, foram adaptados para estilos de vida semiaquáticos. As espinhas vertebrais da cauda de Ichthyovenator eram extraordinariamente altas, sugerindo - como nos crocodilianos de hoje - que a cauda pode ter ajudado na natação. Ichthyovenator viveu ao lado de dinossauros saurópodes e ornitópodes, bem como bivalves, peixes e tartarugas. (pt) Ихтиовенатор (лат.

Вид існував в Азії у крейдяному періоді, 125—113 млн років тому. На спині іхтіовенатора був дивний гребінь, що звужувався по середині спини, а далі знову піднімався. Це гребінь використовувався для терморегуляції тіла. Ще динозавр мав крокодилячу морду та перетинчасті лапи. Іхтіовенатор вів напівводний спосіб життя та живився рибою.
