Featured Cool little rock, or something else?

I saw this and my first thought was "Someone on Antiquers will know what it is"
It looks and feels like a rock. cold to the touch. First pic shows the size.

Sedimentary. imo...

 

I believe that is a interstellar magnetic node, one of five total placed on earth by advanced extraterrestrials during the Pliocene, and, when arranged into a specific geometric shape with the four other nodes, will send a cosmic message to the mothership that Earth is now finally ready for the Dawn of the New Age.


(just being silly; forgive me)

 

Sounds reasonable to me.

Cool rock!

 

A baked potato. Just kidding.

 

It's your new good luck charm!

 

A really good worry stone - you can look at it and worry that the aliens who dropped it will come back to find it.

 

BUT.............it was GOOD!!!!!!!!!!!!!!!!!!!!!!!!!
AAAAAND VERY creative, I MUST SAY!!!!

 

Looks like the pupae of some alien creature. I wouldn't turn my back on it.

 

Good. Keep it cold, you don't want it to hatch.
It is pretty though.

 

Looks like a fossilized bud off a fir tree (or some kind of tree from the Jurassic period!)

 

I don't know what it is... But WAY COOL!

 

Possibly a conglomerate that has been well rolled by ocean or stream.

 

Thank you all very much for your more than interesting answers.
I am still not sure what it is, but I hope it isn't alien!

Or fossilized poop. Not sure I'd want poop.

 

It sounds better when you say "coprolite".

 

Alas it isn't even useful as fertilizer. Gag gift for a 12 year-old, or older, male perhaps?

 

My granddaughters got coprolite in their stockings last year. They loved it ( and knew what it was at 8 & 9 years old including the correct name. )
