Do you mean "meteorite"?

note point 41 - found on a beach

Frankly, that looks a little like a construction brick fragment, eroded by waves on a stoney beach.

Is it uncharacteristically heavy for its size?
Stoney meteorites are unusually dense.

See if the reverse is true and if a needle or iron filings sticks to the stone.
OK, so it's not magnetic; it's ferrous.
It would be cool to get a measurement of its density.
1] Weigh it (in grams).
2] Measure its volume.
- Put a small bucket or pitcher on a pan, and fill the bucket to the brim with water.
(A drop of dish soap will remove the meniscus (surface tension), allowing you to get a flat surface on the water.)
- Wipe away any spillage from bucket and pan.
- Tie a string around the stone.
- Gently place the stone in the bucket. It will overflow into the pan.
- Pull the stone out (so you don't spill any excess).
- Take the bucket out of the pan.
- Pour the pan contents into a measuring cup.
- Read the volume from the measuring cup.
- Convert to cm3 (1mL = 1cm3)
3] Calculate the density in g/cm3.
For reference, granite is about 2.75g/cm3.
A stony meteorite will be about 7 - 8g/cm3

I dont have a scale besides a bathroom scale but id say it weighs about a pound maybe a little less and here is a few pictures compared to a penny 20170227_140713.jpg20170227_141400.jpg 20170227_141419.jpg

Judging by the scale wrt the penny, I'll put its average diameter at 5.3cm.
This gives a volume of ~78cm3.
With a mass of 131g, that gives a density of about 1.7g/cm3.

Hi Frogman,
What did you think of the self-test check-list and Some Meteorite Realities, links I sent in my earlier post? Is seems to me that, you are at the point in your inquiry where you will need to saw your rock in two or cut off a side with a tile saw, or you might try a streak test.
A type of rock that are often mistake for meteorites are those composed of iron oxides like hematite and magnetite because such rocks are denser than most common rocks. Hematite and magnetite can be recognized by the streak test. Scrap your rock against the unglazed side of a white ceramic tile or, the UNGLAZED bottom of a white coffee cup, or a toilet tank cover. Hematite and magnetite streaks are easy to make, almost like chalk on a sidewalk. Meteorites give NO streak or only a weak grayish streak, and only if you press hard. Absence of a streak does not indicate that the rock is a meteorite, since many terrestrial igneous rock will not give a streak.

Good luck and have fun.
Perhaps someone you know, or a friend of a friend, does tile work and has a tile saw. Maybe you could use some very rough sand paper, a grinder or a mill file like one uses to sharpen blades.
It doesn't look like a meteorite too rough looking. Has the appearance of pink granite with inclusions of quartz.

I would guess ferruginous sandstone (an iron ore). Possibly an arkose depending on feldspar content.
You may not want to do this but a geologist would take a hammer to the rock to examine an unweathered surface.
Which Lake Erie beach in particular?
My guess would be a lump of highly corroded actual iron.

Wouldnt iron stick to a magnet more. i put a magnet on it and it falls right off, there is barley a attraction. its flat on the bottom and the top is egg shaped. I filed a small spot down the top layer turns to dust but underneath seems like solid metal almost and the file runs smooth across it
