Turtle recall?

The fossil of a half-shelled turtle has been discovered in China.
Two sets of evolutionary scientists of opposite views are arguing fervently that it completely supports their evolutionary fantasy. Hmm!
This all shows that evolution is so frequently down to the interpretation of the evidence available.
Problem is of course, it may just be what it appears to be - a half-shelled turtle; a previously unknown species.
Similarly, it could be a degenerated version of a turtle which lends no help whatsoever to the evolutionary hypothesis.
But as evolutionists are so emphatic in their guesswork ....
