Links of London Sweetie Bracelet Mosasaurs are an extinct group of marine reptiles Charm Bracelets Outlet, and depending on the particular species Links of London Necklace, varied from about 10 feet (3 meters) in length Buy Links Charm Bracelets, up to a maximum of 57 feet (17.5 meters). These reptiles lived during the latter part of the Cretaceous period of the Mesozoic Era (from about 96 million years ago to about 65 million years ago) Links of London Fairy Godmother Charm, and spent their entire lives at sea. Mosasaurs were carnivores eating fish Links of London Flutter & Wow 18ct Gold Stud Earrings, sea urchins Links Ring, turtles, and shellfish. Although they lived at the same time as many of the dinosaurs Links of London Sweetie Bracelet with One Starfish Charm, and like the dinosaurs became extinct during the Cretaceous-Tertiary mass extinction Wholesale Links of London Necklaces, Mosasaurs were not dinosaurs, but lepidosaurs (the same taxonomic group which includes lizards Links of London Classic Smiley and Rown Charm Bracelet, snakes and sphenodonts such as the tuatara).The evolution of Mosasaurs is quite an interesting topic of speculation and debate. Many similarities have been observed between Mosasaur anatomy and that of monitor lizards Links of London Sweetie Bracelet with One Gold Heart Charm, and it is thought that Mosasaurs may have evolved from aigialosaurs Links of London Marine Shell Sweetie Bracelet, which were semi-aquatic lizards of the early Cretaceous period Links of London Four Leaf Clover 18ct Gold & Diamond Charm, and are themselves believed to be related to monitor lizards.Another possibility is that Mosasaurs may share a common ancestor with snakes - both animals have very similar jaws and reduced limbs. The idea of a Mosasaur-snake link of this type was first proposed by Edward Drinker Cope way back in 1869. In the 1990s fossils were found showing early snakes with vestigial limbs living in marine environments Links of London Red Kangaroo Charm, and which was consistent with this hypothesis. More recently however some other early snake fossils have been found Links of London Cuff, and these seem to show early snakes living a burrowing lifestyle in a terrestrial environment.By S. Tanna.
