Fossils on Mars - A Collection of Evidence

Fossils are rare.  Go take a walk sometime, even in an remote mountain, or hilly countryside, where not many folks go.  Look for fossils.  See how many you find.

You have GOT to be kidding me... You have absolutely no idea what you are talking about.  Try turning off the computer and go out into the real world

Any place where you find limestone you will find TONS of fossils
Any place where you find shale you will find TONS of fossils

Gobi desert Dinosaur bones are just lying around on the surface eroded out of the rock by winds
Road cuts are great... and rain washes out new ones daily from the mud rock

Maybe you just don't know where to look... just ask the local rock hound group in your area. Best place is limestone quarries... just ask permission and go on a Sunday

They don't form on the surface.  Typically almost all are deposited as sediments by moving water.

Would you PLEASE stop spreading such disinfo... Ever heard of petrified wood? Its lying around all over the Arizona and Nevada desert. Those are tree fossils formed by silicas replacing the organic material. Opal beds same thing in Australia and Nevada the wood and sea shells are replaced by silica spheres...

THIS is the Gobi Desert... these people are picking up specimens just lying on the ground... dinosaur bones... I have a huge egg from the Gobi



National Geo did a special on that area skulls etc just lying on the surface

Sandstone Fish
Gobi desert



Same in Utah near Delta... pay the owner 20 bucks in a few hours you will have hundreds of dollars of specimens... same in the Trilobite beds in Delta

Here is a fossil just lying in the open on an eroding cliff



Eroding cliffs reveal new fossils every year.

Polystrate Fossils: In a thousand locations including the Fossil Cliffs of Joggins, Nova Scotia, polystrate fossils such as trees span many strata disproving the claim that the layers were deposited slowly over millions of years

If you are going to debunk at least know what you are talking about

There is a reason that the most abundant fossils found on our own planet are marine fossils.

The reason is there are a lot of oceans and seashells reproduce in multitudes... but dino bones, petrified trees, etc are found all over the deserts in the US, China and other places  What is RARE is full specimens intact...

I am willing to bet you have walked on fossils and never noticed them. September is here and the rocks are cooler... time to go get more

This one is a maybe... but looks good so I will add it here

This just in!

This is a good one, best I have seen in some time. It isn't the RAT tool mark... this is actually embedded in the rock

It's not embedded in the rock because that's sand.

And yes, it's a mark of a screw from the robotic arm.

well,whatever it is appears to raised in the center, not an indentation...

[ArMaP]

Yes, because it was made with this:

That cross looks exactly like the blade on my meat grinder. Not saying it is. Please don't jump my s***.

[ArMaP]

That cross looks exactly like the blade on my meat grinder.

I know what you mean, I have one of those.

[The Seeker]

Yes, because it was made with this:

I disagree, Armap, for there is exactly nothing in that pic you posted that even faintly resembles anything in that image; I am a tool and die maker,custom fabricator, among many other skills, used to reading engineered drawings and fabricating same;I repeat, there is nothing in that pic that even faintly resembles that image...

@Irene: it does look exactly like the cutter blade in a meat grinder

[ArMaP]

I disagree, Armap, for there is exactly nothing in that pic you posted that even faintly resembles anything in that image

Do you really think there's exactly nothing in common with both images?



OK...

[The Seeker]

  Allright, after cropping the images and doing an overlay, I see what you are saying; but at the same time there are features of the embossed impression that do not match exactly that are demarcated by the black line that have no corresponding surfaces on the screw flange...

and I was examining the inner sections of the head assembly when I made my earlier statement...

Well it may satisfy our resident skeptic but I am not buying it.  The screw sits in a beveled countersunk recess...  it looks similar but is it the same size?

Okay back to fossil Hunting

Has Curiosity Found Fossilized Life on Mars?
There are compelling structures in a slab of sedimentary Mars rock, but their discovery alone won't prove there was ancient life on Mars.

Time and time again, as we carefully scrutinize the amazing high-resolution imagery flowing to Earth from NASA's Mars rover Curiosity, we see weird things etched in Martian rocks. Most of the time our brains are playing tricks on us. At other times, however, those familiar rocky features can be interpreted as processes that also occur on Earth.

VIDEO: Did a Mars Meteorite Finally Reveal Life On Mars?

Now, in a paper published in the journal Astrobiology, a geobiologist has related structures photographed by Curiosity of Martian sedimentary rock with structures on Earth that are known to be created by microbial lifeforms. But just because the structures look like they've been formed by microbes on Mars, does it mean that they were?

The image in question was snapped by Curiosity of the Gillespie Lake outcrop situated in the Yellowknife Bay area of Gale Crater that the rover arrived at on Dec. 17, 2012, on sol 125 of its mission. It was soon realized that the Gillespie Lake rock is sedimentary sandstone, formed when Mars possessed surface water. As such, there are many likenesses between the rocks found in Yellowknife and sedimentary rocks on Earth. For example, the layering of sedimentary rock and conglomerations contained within these layers led NASA scientists to realize that Curiosity is exploring an ancient lake bed.

In her analysis, Noffke is keen to emphasize that she hasn't found proof of ancient Mars life, only that her hypothesis provides a compelling explanation for the formation processes behind the shapes in the surface of Mars sedimentary rock.

"All I can say is, here's my hypothesis and here's all the evidence that I have," said Noffke in an Astrobiology Magazine article, "although I do think that this evidence is a lot."

There have been countless claims pointing to evidence of ancient life on Mars, many of which have since been proven to be, at most, wishful thinking, but this new study has garnered some cautious praise from planetary scientist Chris McKay, of NASA's Ames Research Center and an associate editor of Astrobiology.

NASA's Bold Plan to Hunt for Fossils on Mars

LOL well about time they caught up with us

A rover headed for the red planet will perform an unprecedented search for rocky remnants of dead Martians—so where should we send it?

By Mark Strauss
PUBLISHED OCTOBER 17, 2016
Nearly four billion years ago, when Earth was coming alive, Mars was gradually choking to death. The thick atmosphere that had warmed the red planet was leaking into space, and plummeting temperatures caused Martian lakes and rivers to freeze, turning the wet surface into a dry wasteland.

But it's possible life took root in those early years. And very soon, a NASA robot will arrive at Mars with the goal of collecting rock samples that might contain ancient fossils, perhaps helping to answer one of humanity's most fundamental questions: Are we alone in the universe?

First though, would-be Martian fossil hunters will have to decide where, exactly, to send that robot.
