SUPERIOR Post; enjoyed the Images, too -- and the Spacing (which is important, for easy #reading ).

Liked when, in yr Article, you wrote: "From studying fossils dated back to the middle Jurassic era, researchers have discovered that very little morphological changes have occurred in members of the Cryptobranchidae family over the past 170 million years, this has led some to refer to members within this family group as living Fossils."

Just thought it was kind of Amusing that people think of them as 'living Fossils' . Guess there are a few Family/Species that are thought of this way.

Didn't realize that Salamanders were very delicate creatures -- they're not unattractive, I think they're better to look at than a crocodile !

Kudos .. and will Look 4 more !
