Snake with four legs — paleontologists’ dream come true — turns out not to be a snake

Hopes dashed:

Filling in the links of the evolutionary chain with a fossil record of a ”snake with four legs” connecting lizards and early snakes would be a dream come true for paleontologists. But a specimen formerly thought to fit the bill is not the missing piece of the puzzle, according to a new Journal of Systematic Palaeontology study led by University of Alberta paleontologist Michael Caldwell.

“It has long been understood that snakes are members of a lineage of four-legged vertebrates that, as a result of evolutionary specializations, lost their limbs,” said Caldwell, lead author of the study and professor in the departments of biological sciences and earth and atmospheric sciences.

“Somewhere in the fossil record of ancient snakes is an ancestral form that still had four legs. It has thus long been predicted that a snake with four legs would be found as a fossil.”

In a paper published in the journal Sciencein 2015, a team of researchers reported the discovery of what was believed to be an example of the first known four-legged snake fossil, an animal they named Tetrapodophis amplectus.

This was the story in 2015:

So what happened?

“There are many evolutionary questions that could be answered by finding a four-legged snake fossil, but only if it is the real deal. The major conclusion of our team is that Tetrapodophis amplectus is not in fact a snake and was misclassified,” said Caldwell. “Rather, all aspects of its anatomy are consistent with the anatomy observed in a group of extinct marine lizards from the Cretaceous period known as dolichosaurs.”

In any event, inconveniently, there is also a snarl about removing the fossil from Brazil.

So researchers are still looking for a snake with legs.

The paper is open access.

    Darwinists misclassified something ? NO WAY !!!

    Human invention is also jerky or cladistic. Intermediate “evolved” forms don’t last. They are tried, but ultimately the successful new invention comes out of a fresh thought. The “evolved” forms only serve to show inventors what WON’T work.

    So the Lord God said to the serpent, “Because you have done this, Cursed are you above all livestock and all wild animals!You will crawl on your belly and you will eat dust all the days of your life.

    Well, Bible says the snake had legs and then was “genetically engineered ” by God (who removed the snake’s legs ) Technically can be said is a different type of animal . 🙂 Question is how in the world would have known Moses about snakes with legs ? Unless….

    @CD
    You were sure this was a real missing link, but were disappointed?
    You were sure this proved the Bible was wrong, but were disappointed? Again?
    You were sure that misinterpreting the Bible would pass unnoticed?
    As Dr. Samuel Johnson said, “ My dear friend, clear your mind of cant.”
