Stone meteorites will have a melted/glazed surface. Others are either iron or iron in stone. All show signs of extreme heat.
Correction: Not all metallic ones are iron, I learned something today.

More pictures as requested.
I found this on my property several years ago.
I live about 10 miles north west of phila. Pa.
In a small town called Roslyn Valley.
I'm at the high end of town not in the lower end that floods on occasion if that means anything.

It's a prehistoric, petrified giant snake head. Look at the 3rd pic down in reply # 52. See it's eye sockets, nose and outline if its mouth?

Ouch, hope you get it all sorted.
Thanks for all the well wishes.
I'm on the road to recovery

Doing that is on my bucket list.
Here is a better head-on picture.
Funny the human brain is wired, to see familiar images in things.
It does have some kind of facial recognition though.

Guessing a hunk of limestone that broke free from a sinkhole/small cave, Yeah, that`s the ticket.
If you see a face on it, have an artist fill in the details and display it

.one geology method to identify basalt
Get a piece of unglazed tile, scratch it hard with the rock.
If it leaves a brownish streak it could indicate the presence of iron rich minerals, the brown streak could be
Oxidizing iron (rust) particles
The OP said that it was not magnetic.
There still could be particles of iron in it, but not enough to be "feel" magnetic
Iron could explain the "heaviness"
(Density) of the rock.
Limestone was mentioned
Place a few drops of dilute hydrochloric acid on the rock, if it sizzles or bubbles it will more than likely be limestone, from ancient sea shells, which are composed of calcium carbonate.

I did test for Limestone negative.
I will try the tile test tomorrow.
Thanks.

Thanks.
If you could chip off a very small piece to get to the unweathered rock, the test will be more accurate
Gotcha 
Also check out Mohs hardness scaleGotcha
Could you send me some close ups ?

When I was a kid and in 4H, I found a rock similar looking.
I asked our conservation leader what it was. He told me it was leaverite. I said really. He said yup leaverite there.
On a more serious note. If you have a college with a geology department they may be able to tell you what it is, or you maybe able to go to a the county agriculture extension office.

It took me a week to remember this . . . Was talking to one of Registered Geologists on the Dam Job I was on in 2019 and they mapped every inch of this overexcacation extensively.
I asked about a particular rock and he stoically said " It's a sex rock ". I figure he's yanking my chain and he says " Yep, just another ******* rock ".
Geologist humor I guess. Not to mention we're busy and I probably wouldn't understand anyway.
Also if you have a local arts and sciences museum you might take it there. There may be someone who has some knowledge of geology.
I had it checked out. It's from China.
I actually have someone that's going to look at it this weekend after I sent them a few pictures.
Philadelphia has plenty of museums . This one my be of particular interest to some folks.
The Mutter Museum Phila. PA.
