It lived during the Cenomanian, approximately \u003cstrong data-start=\"304\" data-end=\"332\"\u003e100–94 million years ago\u003c\/strong\u003e, in fluvial and deltaic ecosystems associated with the large continental systems of northern Gondwana. Its name means “shark-toothed lizard”, referring to the laterally compressed and serrated shape of its teeth, functionally comparable to blades designed for slicing tissue.\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"610\" data-end=\"1231\"\u003eTaxonomically, \u003cem data-start=\"625\" data-end=\"656\"\u003eCarcharodontosaurus saharicus\u003c\/em\u003e belongs to \u003cstrong data-start=\"668\" data-end=\"693\"\u003eCarcharodontosauridae\u003c\/strong\u003e, a lineage of large allosauroid theropods that included some of the largest terrestrial predators known, such as \u003cem data-start=\"807\" data-end=\"823\"\u003eGiganotosaurus\u003c\/em\u003e and \u003cem data-start=\"828\" data-end=\"840\"\u003eMapusaurus\u003c\/em\u003e. The original material described in the early 20th century came from Egypt and was destroyed during the Second World War, meaning that much of our modern understanding of the species relies on material discovered later in North Africa. New partial skulls and postcranial remains have made it possible to reassess its anatomy and distinguish it from other large African carcharodontosaurids.\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"1233\" data-end=\"1717\"\u003eFrom a morphometric perspective, \u003cem data-start=\"1266\" data-end=\"1297\"\u003eCarcharodontosaurus saharicus\u003c\/em\u003e was an enormous theropod. Modern estimates commonly place large adults at around \u003cstrong data-start=\"1379\" data-end=\"1410\"\u003e12–13 metres in body length\u003c\/strong\u003e, with an approximate mass of \u003cstrong data-start=\"1440\" data-end=\"1454\"\u003e5–7 tonnes\u003c\/strong\u003e, although these values may vary depending on the specimen and reconstruction method. Its body was bipedal, elongated and muscular, with powerful hind limbs, a long tail for balance and relatively reduced forelimbs that remained functional and bore three fingers.\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"1719\" data-end=\"2259\"\u003eThe skull was one of its most impressive features. In large individuals it reached a length of around \u003cstrong data-start=\"1821\" data-end=\"1843\"\u003e1.5 metres or more\u003c\/strong\u003e, while remaining relatively lightweight for its size thanks to extensive cranial fenestrae. The snout was tall and deep, the jaws were long, and the teeth were laterally compressed, recurved and equipped with fine serrations along both cutting edges. This dentition was adapted to inflict deep cuts and extensive wounds rather than crushing bone through highly concentrated bite forces like those of tyrannosaurids.\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"2261\" data-end=\"2877\"\u003eThe biomechanics of \u003cem data-start=\"2281\" data-end=\"2302\"\u003eCarcharodontosaurus\u003c\/em\u003e probably favoured attacks based on rapid bites, repeated slashing injuries and blood loss in large prey. Its large skull, powerful neck musculature and blade-like dentition suggest a strategy specialised for attacking large vertebrates, possibly including sauropods, ornithischians and other dinosaurs inhabiting the ecosystems of North Africa. Although its absolute bite force would have been considerable because of its size, cranial morphology indicates that it was not constructed exclusively to withstand the enormous crushing loads associated with \u003cem data-start=\"2857\" data-end=\"2876\"\u003eTyrannosaurus rex\u003c\/em\u003e.\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"2879\" data-end=\"3333\"\u003eThe head also displayed rugose surfaces and bony ridges around the orbital and nasal regions. These structures may have supported keratinous coverings or ornamental soft tissues and could have played roles in visual recognition, display or interactions between individuals. The exact form of these tissues is not preserved, so external reconstructions should remain conservative and be based directly on the texture and morphology of the underlying bone.\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"3335\" data-end=\"3820\"\u003eThe neck was robust and heavily muscled to move and stabilise the enormous skull during prey capture. The vertebral column and pelvic girdle supported a powerful torso, while the hind limbs were adapted to the terrestrial locomotion of a predator weighing several tonnes. It would not have been a specialised runner comparable to smaller theropods, but it was probably capable of rapid movement over relatively short distances and sufficient manoeuvrability to attack large herbivores.\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"3822\" data-end=\"4345\"\u003e\u003cem data-start=\"3822\" data-end=\"3853\"\u003eCarcharodontosaurus saharicus\u003c\/em\u003e inhabited some of the most extraordinary ecosystems of Cretaceous Africa. In North Africa, it coexisted with other large predators such as \u003cem data-start=\"3993\" data-end=\"4006\"\u003eSpinosaurus\u003c\/em\u003e and abelisaurids, as well as giant crocodyliforms, large fishes, turtles, pterosaurs and sauropods. This concentration of large carnivores was probably possible because of the diversity of ecological niches available within extensive river systems, where different predators could specialise in terrestrial, riparian or aquatic resources.\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"4347\" data-end=\"4783\"\u003eEcologically, \u003cem data-start=\"4361\" data-end=\"4382\"\u003eCarcharodontosaurus\u003c\/em\u003e would have occupied one of the highest levels of the terrestrial food chain. Its enormous size, deep skull and slicing dentition identify it as a macropredator specialised in large vertebrates. Its coexistence with other apex predators demonstrates that the Cenomanian ecosystems of North Africa were highly productive and capable of supporting an exceptionally diverse community of large carnivores.\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"4785\" data-end=\"4819\"\u003e\u003cstrong data-start=\"4785\" data-end=\"4819\"\u003eApproximate Replica Dimensions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"4821\" data-end=\"4868\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\u003cstrong data-start=\"4821\" data-end=\"4832\"\u003eMedium:\u003c\/strong\u003e 87 mm high\u003cbr data-start=\"4843\" data-end=\"4846\"\u003e\u003cstrong data-start=\"4846\" data-end=\"4856\"\u003eLarge:\u003c\/strong\u003e 145 mm high\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Dino and Dog","offers":[{"title":"Mediana \/ Sin imprimar","offer_id":62088380612876,"sku":"DC-1576-MEDIA-SINI","price":27.6,"currency_code":"EUR","in_stock":true},{"title":"Mediana \/ Imprimado","offer_id":62088380645644,"sku":"DC-1576-MEDIA-IMPRI","price":30.6,"currency_code":"EUR","in_stock":true},{"title":"Mediana \/ Pintado a mano","offer_id":62088380678412,"sku":"DC-1576-MEDIA-PINTA","price":99.5,"currency_code":"EUR","in_stock":true},{"title":"Grande \/ Sin imprimar","offer_id":62088380711180,"sku":"DC-1576-GRAND-SINI","price":42.0,"currency_code":"EUR","in_stock":true},{"title":"Grande \/ Imprimado","offer_id":62088380743948,"sku":"DC-1576-GRAND-IMPRI","price":49.0,"currency_code":"EUR","in_stock":true},{"title":"Grande \/ Pintado a mano","offer_id":62088380776716,"sku":"DC-1576-GRAND-PINTA","price":149.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/1106\/7660\/files\/3_385f78d7-eac8-485e-bbfd-04df52fd9cc5.jpg?v=1789646007","url":"https:\/\/dinosauriacreatures.com\/en\/products\/carcharodontosaurus-saharicus","provider":"Dinosauria Creatures","version":"1.0","type":"link"}
