Another interesting category in the classification of reptiles is marine reptiles. The great majority of these creatures have become extinct, although turtles are an example of one group that survives. As with flying reptiles, the origin of marine reptiles is something that cannot be explained with an evolutionary approach. The most important known marine reptile is the creature known as the ichthyosaur. In their book Evolution of the Vertebrates, Edwin H. Colbert and Michael Morales admit the fact that no evolutionary account of the origin of these creatures can be given:

Fossil ichthyosaur of the genus Stenopterygius, about 250 million years old.

The ichthyosaurs, in many respects the most highly specialized of the marine reptiles, appeared in early Triassic times. Their advent into the geologic history of the reptiles was sudden and dramatic; there are no clues in pre-Triassic sediments as to the possible ancestors of the ichthyosaurs… The basic problem of ichthyosaur relationships is that no conclusive evidence can be found for linking these reptiles with any other reptilian order.103

200-million-year-old ichthyosaur fossil.

Similarly, Alfred S. Romer, another expert on the natural history of vertebrates, writes:

No earlier forms [of ichthyosaurs] are known. The peculiarities of ichthyosaur structure would seemingly require a long time for their development and hence a very early origin for the group, but there are no known Permian reptiles antecedent to them.104

Carroll again has to admit that the origin of ichthyosaurs and nothosaurs (another family of aquatic reptiles) are among the many "poorly known" cases for evolutionists.105

In short, the different creatures that fall under the classification of reptiles came into being on the earth with no evolutionary relationship between them. As we shall see in due course, the same situation applies to mammals: there are flying mammals (bats) and marine mammals (dolphins and whales). However, these different groups are far from being evidence for evolution. Rather, they represent serious difficulties that evolution cannot account for, since in all cases the different taxonomical categories appeared on earth suddenly, with no intermediate forms between them, and with all their different structures already intact.

This is clear scientific proof that all these creatures were actually created.
