Four-legged Snake Fossil Stuns Scientists, Ignites Controversy
sciencehabit writes: Scientists have described what they say is the first known fossil of a four-legged snake. The limbs of the 120-or-so-million-year-old, 20-centimeter-long creature are remarkably well preserved and end with five slender digits that appear to have been functional (abstract). Thought to have come from Brazil, the fossil would be one of the earliest snakes found, suggesting that the group evolved from terrestrial precursors in Gondwana, the southern remnant of the supercontinent Pangaea. But although the creature's overall body plan—and indeed, many of its individual anatomical features—is snakelike, some researchers aren't so sure that it is a part of the snake family tree.
The biblical literalists are going to love this one.

The snake also recently stated that POW's are exempt from War Hero status.

So it could breathe fire, as well? It sounds like they have not found a snake, but a fire-breathing dragon!

Surprised it wasn't classified as a skink though I'm more of a mammal enthusiast than a reptile one. Either way I'm curious if 20cm is its full grown size or if it is a baby dragon.
Need to know if it can talk!

Four-legged Snake Fossil Interests Scientists, Ignites Scientific Interest
FTFY.

yep
The site in Brazil (between 3 states) is know for it's type of rocks and a place to steal fossils. :)
RTFA. (Yeah, I know, this is /. )
The limestone the fossil is embedded in, and the coloring of the fossil, are indicative of northern Brazil. Apparently either the original collector, or the owner of the private collection the fossil used to be in, didn't care to document the provenance (when/where found, under what circumstances) of the fossil, diminishing its scientific value. (This is why professional paleontologists and archeologists get pissed off at (most) amateur collectors. Some amateurs do a fine job, but with most it's like trashing a crime scene before the forensics guys show up. Less of a concern with dime-a-dozen invertebrate fossils.)
If it was collected post-1942 (when it became illegal to export fossils from Brazil), that may explain the lack of documentation -- without which it's hard to prove that it was an illegal export.
I glanced through the above story about Hillary and misread the title of this story as "Four legged Senate fossil..." but then I remembered that Stromberg Thurmond died a few years back.
I agree, you can be a war veteran and a prisoner of war but you can not be a war 'hero' if all you did was sit in jail... and this is what John McCain ddid for almost the whole war.
Uh, you are aware that he did do other things in the war, right? Sitting in jail (by which you mean, POW camp) is not "all" he did. It was his 23rd bombing mission, not his first, on which he was shot down. And that by this time he'd been awarded the Navy Commendation Medal and the Bronze Star.
I'm no fan of McCain, but I don't like personal attacks. Criticize him for his politics, not his history.
On the surface it appears they are questioning cross-specie evolution and how amino acids starting forming proteins (presumably without any RNA / DNA). But it is really an argument toward theocracy and away from secular society. Good luck with that. One of their arguments again cross-specie evolution is the lack of transitional fossils. This may be determined to be such a fossil. I am no scientist, but every theory should be questioned, it is science.
Oh, so they date the sand part of the sediment that was made into sedimentary rocks and consider THAT the age of the fossil?
You do realize that the elements you mention are pretty much not part of the fossil, but part of the substrate which contains the fossil. What you are suggesting they are doing is going to a wall built yesterday and claiming it's 100 years old because of the age of the barn wood that the wall was covered in.
I don't think the process of dating fossils is done that way... Last I heard they go to the geologists and ask them how old the rocks are.... Of course the question then becomes how the geologists know how old the rocks are.... I sure hope they don't go ask the biologists to date the fossils they see...

There, FTFY. HTH.
This is Slashdot. Science is only questionable when it agrees with the bible.
Genesis 3:4, for those wondering what the sequence specifics are that are the current cause for rejecting science, if necessary.
Title seems to be simple click bait meant to attract creationists and their opponents.

Carbon dating is useless on fossils. Firstly because they are far too old for the ratio to be measurable, and secondly because they don't actually contain any carbon of atmospheric origin to date.
There are other forms of dating used for fossils though.
I like how it's hugging the little furry mammal in the artist's conception. It's representative of the long bond of love and friendship that exists between us and our reptilian friends.

I've calculated my velocity with such exquisite precision that I have no idea where I am.
Carbon dating isn't used for things older than about 100,000 years. Anything older than that uses other radioisotypes to determine age, which don't vary with atmospheric composition.

no
Actually, that's incorrect.

All fossils date less than 50,000 years. This is not a problem for creationists, but it makes evolutionists uncomfortable so they don't do it.
Peter predicted that you would "deliberately forget" creation 2000 years ago...
But not because they don't contain Carbon-14. Everything contains Carbon-14 and most fossils date to around 25,000-30,000 years ago if you Carbon-14 date them.
Peter predicted that you would "deliberately forget" creation 2000 years ago...
Yep. This is EXACTLY how they date fossils 90+% of the time. And you believe it as if they did a test or something actually scientific.
Peter predicted that you would "deliberately forget" creation 2000 years ago...
Actually, this is a more correct statement than most people make on this subject. Both creationists and evolutionists have made wild guesses in the past that have turned out to be absolutely false. The lack of hard scientific data makes this field less scientific than most people realize.

According to a paper which failed peer review.
Well, after it's been in the ground long enough, it doesn't contain carbon-14 any more, because it decayed to nitrogen. If you use carbon dating on those, there isn't enough left to get an accurate reading, which is exactly what you'd expect to happen.

Sure they have something. We don't know what it is. Since it's a fossil we don't know how it happened. Could it be something else happened to land on it after death or was below it before death? We don't know. Show me more with the bone structures in the same place. Then we'll have something. Now it's just a curiosity. Need more proof.
