Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semiaquatic life in a marine environment. Only about 100 of the 12,000 extant reptile species and subspecies are classed as marine reptiles, including marine iguanas , sea snakes , sea turtles and saltwater crocodiles .
Mosasaurs became extinct 66 million years ago, at the same time as the dinosaurs. A modern semi-aquatic lizard: the marine iguana. Modern squamates which have made their own adaptions to allow them to spend significant time in the ocean include marine iguanas and sea snakes. Sea snakes are extensively adapted to the marine environment, giving ...
A study in 2009, which examined 94 living species of reptiles, birds and mammals, found that the genetic control of sex appears to be crucial to live birth. It was concluded that with marine reptiles such control predated viviparity and was an adaptation to the stable sea-climate in coastal regions. [ 147 ]

A = Anapsid, B = Synapsid, C = Diapsid. It was traditionally assumed that first reptiles were anapsids, having a solid skull with holes only for the nose, eyes, spinal cord, etc.; [10] the discoveries of synapsid-like openings in the skull roof of the skulls of several members of Parareptilia, including lanthanosuchoids, millerettids, bolosaurids, some nycteroleterids, some procolophonoids and ...
Sauropsida (Greek for "lizard faces") is a clade of amniotes, broadly equivalent to the class Reptilia, though typically used in a broader sense to also include extinct stem-group relatives of modern reptiles and birds (which, as theropod dinosaurs, are nested within reptiles as more closely related to crocodilians than to lizards or turtles).

In 2014, physician Pedro Lucas Porcela Aurelio found the fossil in the town of Paraiso do Sul in Brazil's southernmost Rio Grande do Sul state. He donated it to a local university in 2021, kicking ...
Many of the so-called 'dinosaur' remains found on New Zealand are actually mosasaurs and plesiosaurs [citation needed], both being Mesozoic predatory marine reptiles. The largest mosasaur currently on public display is Bruce, a 65-70%-complete specimen of Tylosaurus pembinensis dating from the late Cretaceous Period, approximately 80 million ...
