There are turtles? -- Anyway, the mammals are preserved with hair; but the
frogs, newts etc. are preserved without feathers or anything similar, and
the champsosaur *Monjurosuchus* is preserved _with scales_. (Like
*Psittacosaurus*.)

3. Why should terrestrial running animals have ludicrously thick layers of
connective tissue in their skin, like what whales and ichthyosaurs* have as
an adaptation to highly efficient swimming?
