Strange Head-Like Fossil (Or just coincidence?)

[Kaushik]

Hello, I have found a strange fossil-like head of a dinosaur (I hope!) but I am not going to hope, because this rock was found in the backyard of my house. I am not sure what it is, but if it is not a fossil, can someone kindly tell me what it is (including the name of the rock and how it got there) and explain why this is just a coincidence.

Interesting concretion that's somewhat suggestive in shape. This may be conglomerate. No evidence of a fossil, but don't give up. It appears you are in the Mesozoic so there's probably such things to find.

I agree. Keep hunting!

This looks like a mudstone/sandstone/chert concretion, to me. (Hard to tell from this picture.)

 No bone texture, no skull morphology.  

 

As to how it got in your backyard? 
Any number of explanations are possible. 
Glacier, construction, human intervention. (Maybe someone else thought it was a dino skull, too.)

Thanks for the kind replies! I will definitely hunt for some actual fossils soon!
