Did marine reptiles have gills?
More than a dozen groups of marine reptiles are recognized from the Mesozoic (Carroll 1982). These reptilian ancestors lost their gills at one point in time, so their descendents could not breathe in water unlike fish or some amphibians.Click to see full answer.

More than a dozen groups of marine reptiles are recognized from the Mesozoic (Carroll 1982). These reptilian ancestors lost their gills at one point in time, so their descendents could not breathe in water unlike fish or some amphibians.Click to see full answer. People also ask, how do marine reptiles breathe?Breathe using lungs rather than gills. Thus, reptiles in the ocean may be able to hold their breath to go underwater, but eventually need to go to the surface to breathe. Have a three- or four-chambered heart.Beside above, what happened to marine reptiles? During the late Jurassic however, they went into decline, and they went extinct during the mid-Cretaceous, some 25 million years before the K/T extinction event. Predation by larger marine reptiles, such as the pliosaurs and mosasaurs may have also lead to the extinction of the ichthyosaurs. Beside above, when did marine reptiles evolve? Marine reptiles arose in the Early Triassic, some 250 Ma, and dominated Mesozoic seas until their demise by the end of the Cretaceous, 65 Ma (1, 2).Do reptiles live in the ocean?All major reptile groups, i.e. the snakes, lizards, turtles, and crocodiles, have at least a few members that enter marine habitats even though they may have never completely adapted to a life in the open sea. Here we give an overview of those reptiles that are found exclusively or at least occasionally in the oceans.
