What is this Swiss cheese looking rock?

0 votes

My parents believed it to be a meteorite.  I'm not so sure, but can't find a match. It also pulls a magnet but doesn't  hold it...

Just a suggestion, but maybe it could be piddock rock. Check it out on Google Images, sort of resembles what I see in your pictures. I'm no expert, just trying to offer input.

Thank you so much JohnBagel. That's an excellent suggestion and does resemble what I have. Thanks for responding :)
Sure thing! It would sure be awesome if it were a meteorite! It does honestly resemble one too, I just don't think the holes would be all the way through in a meteorite though. I'm not sure if piddock rock is a specific mineral, I just searched rocks with holes and found it
Definitely not a meteorite. Very dense. Most meteorites are made of iron or metal and would be magnetic. The holes suggest water or air bubbles in formation. I don't see fossil matter. Hope that helps.

Reminds me of fossil rocks I find where a fossil sea creature would drill down into the rock. I can't remember what they are called but I have tons of them from Lake Erie. The fossil critters and the rocks.

Lake Erie was an inland salt water sea. The fossil record is obvious. I have hundreds of the fossils and the burrowing ones do not look like this. These holes seem way to smooth for animal manufacturing. Also not even a bit of fossil in the surrounding rock...
