Hello!

 

Someone I know found this rock close to his house. The rock is very hard, can't make no scratch on it. I though it could be a fossil, like a limpet track or I don't know...? Does someone know what it is? 

 

Thank you!

Welcome to The Fossil Forum. I cropped and rotated your photo so we can see it better. It is not a limpet track fossil since limpets only move slowly on solid substrates such as rocks and not in soft sediment that your rock probably was at one time. Your rock is interesting and might be a fossil such as a burrow or stromatolite that is exposed in a 3-D pattern on the rock. We should let others chime in to give us other ideas as to how the rock was formed. Do you know the age, name, locality and type of rocks that occur where the rock was found? Those facts might give us important clues for an ID.

My goal is to leave no stone or fossil unturned.

Plus one vote for stromatolite! Beautiful find!

That beast looks huge, I hope you didn't have to lug it too far.  One more passenger for the Stromatolites train.  It is quite the show piece!

Stromatolite.  I know there are similar ones from around Saratoga, New York, but did this come from the area of Montreal?  I am going there tomorrow but that is irrelevant.

Stunning! I'd be interested to hear how that beast was moved.

Another vote for stromatolite, though that is probably the best one I've seen. Big congratulations.

Slightly Collenia-like

The taxonomy of stromatolites is not simple,and strictly speaking ,they are not organisms,but sediments.
