I doubt it is a fossil.  It looks rather like agate or flint to me.  They often have that sort of coating.

Suggest you try to break a very small piece off. Is it 'glassy'?  Does it have a concoidal fracture?

I agree with John, looks like flint or agate, the "tanned" surface probably being chalk.

Agree too: looks like flint with chalk coating.

Definitly not chalk, chalk would have a streak. the skin is soft yet very durable like i couldnt possibly remove it. i held a pencil torch to it for about a minute and it is very resistant to heat.  Both chalk and flint are not heavy this weighs 5oz. flint is black.  This rock seems more like clay but it's not clay.  It's not at all glassy. I did break a chunck off.  I could almost stick it back on there it held it's form perfectly.  A little glue and can't even tell it had been broken.  The only reason i took it home was beacause it was heavier than it should have been for it's size.

Flints are not always black.  They have a range of shades of greys and browns.  And it is a very dense form of silicon oxide and the SG often confuses people.

Maybe your idea of clay is correct (we can't see that inside bit, and you didn't describe the fracture) and it is what is left from a fire brick or similar.   I did wonder if it might be furness slag when I first saw it.

Just want to confirm that you guys are able to see this rock. I'm looking at it on a 1920x1080p monitor.  Thats 2million pixels. the picture is 4million pixels so i'm able to see half the detail.   I realize some people may have lower res monitors and not be able to get an idea of what the rock actually looks like.   The surface is so soft and smooth.   It has had a piece broke off it before.  It looks like it grew skin to cover the broken off part. I broke off a pirce and pressed it back together almost. Used glue to hold it there. This rock might be alive.Thanks for the info guys.  

Rocks aren't alive. (Apart from the bacteria living in them, but that's not the same). The resolution of the monitor has no impact on what you can "see" as the image can be scrolled. Also these are JPGs so they've been compressed: I can see the artefacts, so the resolution is not important.

I'm still pretty sure it's flint.

Try scratching the inside part with a steel (make sure it's steel, not stainless steel) nail or knife. Then try scratching the steel blade with it. Flint is silica, which has a hardness of 7, steel has a hardness of around 6.5. So you should be able to scratch the steel with the "flint", but it might be difficult the other way around.

Thank your for your input. 

I assure you that you will see more detail on a high resolution monitor than you would on a lower resolution monitor.  

It could be flint but I did some reasearch and all things are pointing toward meteorite.

The fact that the rock had been broken and litterally grew a skin to cover the broken part could be some type of oxidation.  It sort of glows a buttery yellow in the dark i'd add a pic but I might have to start a new post.

If it glows in the dark I'd throw it far away!!!

I've detirmined the rock is some sort of device sent by ailians to spy on us.  It has a face and several eyes all over it. 

I think it's more likely to be a fossilised potato.  I've recently unearthed some and they're covered in eyes too.

Gus, I've just spat my lunch everywhere reading your comment!
:D

I'm sure you're right indosia

It's not a potatoa or flint or chalk. Slag maybe but i dont know if slag has fusion crust. I'm going to post more pics so you guys can see what I mean by fusion crust.  If you geology guys have no idea what it is then it's all the more likley that it's from outserspace.  I'm also going to post pic the clearly shows the face inside this rock.  The eys protrude out from the rock very detailed.  Or just very rare.  You know how we always send things to mars and they end up broken.  Just like this rock, I hit it with a hammer, broke it and glued it back together good as new.  Almost. didnt need any glue.  Eitherway its very rare and nothing like I've ever scence. I'm 32 by the way, so i've scene plenty of rocks. Look for new post with more pics.

Ok, I give up, it's from outer space.  The reason we've tried to explain it away as a bog-standard piece of flint or whatever is because we're secretly hoping you hadn't identified it correctly as the only known example of spuddite, sent from the spiral galaxy of Yrnoolia which is far far beyond the known limits of the universe and took a whopping 24.78 trillion light years to get here.  What it's purpose is we can only guess at but I'm sure the eyes are watching our every move and waiting for an opportune moment when it can hatch into something that will eventually engulf the Earth in a sticky black substance that resembles Marmite in both texture and taste.

Spot on Gus!

It's possilble.  Not likley but possible.  We  send things to mars with cameras.  Don't we?  I mean we do it to other planets.  Theres no reason to think that other planets dont do it to us.   Ok enough of that.    I'm thinking it's likley a meteorite with fossils though.My  other 2 guesses are thats it's the clay God used to create man with.  At least thats what I plan to sell it on ebay as(lol).   Either that or a piece of slag but I'm leaning toward meteorite or creation clay.  I know it's not flint as flint has no fusion crust and doesnt stay bright in the dark.  This has a very thin yet extremely durable fusion crust, it's very smoth with a odd bubbly surface.

Meteorite with fossils?  Creation clay?  Yep, I'd agree with both.

Yep.  Sounds likely ....after a few pints.
