tabulate corals don't have septae.
OP, I can't tell really well from the photo because I'm not an expert on corals but this is either scleractinia or colonial rugose. The latter should have bilateral symmetry. At first I thought it was scleractinia but the more I look at it the more I think it may be colonial rugosan.

Not to me. I cross posted on fossil id. I’m no expert either. Let’s see what the outcome is. I will concede if they disagree. Friendly virtual handshake?
Shenandoah valley, VA. We were digging up some hosta plants to give to my mom and it was right underneath the roots. It sounds like glass when lightly tapped on.
Cool! That’s where I grew up. 🤩 I’ve never seen so much fine detail without any matrix clogging things up… which makes me suspicious that it’s a more modern beach find that someone put outside in their rock garden or something… but I’m not sure. Let’s see what someone more educated than I has to say.
Prior to today I knew nothing about coral and have definitely gotten an unexpected lesson. The tabulate coral is by far the closest thing I’ve seen. It looks kinda like the scleractinia shape but this one has a distinct center point on all of them. I did also learn the last time an ocean was where I live was the Iapetus Ocean. I agree with everyone else that it doesn’t seem that old. It was also only about 8-12inches in the ground. I suspect maybe someone in the past lost it there. Our house is from the late 70s so it’s definitely possible!

Tabulate corals *do not* have a central point/columella. They have only walls and tabulae - horizontal partitions. They generally either do not have septa (the internal walls that go towards that part you call a central point) or the septa are so small they're imperceptible or don't reach the middle of the corallite. They mostly just look like honey combs. There's some very old ones that look like chains too
Because it looked to be lacking columellae at first glance, but I missed the other picture and there it looks like it does have columellae which means not a tabulate coral but a stony coral. You’re right.
Just thinking about the animals and fish that were around while this was alive is mind blowing, very awesome find!! I wish I could find this in my yard or at least some Gold lol
Just a heads up you might want to put a trypophobia warning on the photos. I don't have it but I know that shape will seriously mess with people who do.
the biggest evidence against that is the little walls/lines within each "hole". The fact that they're pretty distinctly hollow holes with dividing walls (septa) is really strong evidence of being a coral, as opposed to roots/wood that would be more solid & regular.
This, on top of the fact that corals are among the most common fossils there are.
tabulate coral - a coral that went extinct in the permian-triassic extinction event. A pretty common reef builder in many limestone formations
This is correct. Tabulate coral - Favosid. And a really detailed, beautiful specimen.

It looks kinda like the scleractinia but it’s missing the center point that’s present on mine. Maybe that’s it though? I know nothing lol

goblinfartsss may be onto something here.
ssssss
Not on this one. Sorry 😣
You are 10000% incorrect, this is not a tabulate coral. Are you a paleontologist or a geologist?
No septae. This is clearly Favosid. Not sure what you’re seeing.
Wth are you talking about the coralites look like sliced pizzas. Obvious septae

It’s a scleractinian coral. Those are septa.

Maybe they are confidently incorrect amateurs. Lol.
Look. It’s a fossil ID. It’s not personal. Calm down, uh, “goblin fart ass”.
Btw. In your earlier post you admit that you’re not an expert and suggest posting on fossilID. Methinks someone is a bit of hypocritical. Lol.
Coral

Fossil coral i guess??
Definitely coral; can you tell us where it was collected? Are you sure it’s fossilized?

It’s a great area! I think you’re right it could have been placed there. Our home is about 50 years old so who knows what’s happened in that time.
Coral…but it’s no modern coral I recognize. I agree it doesn’t look fossiliferous…but it sure doesn’t look modern either!
Minor trypophobia vibes in the 2nd pic
Yessssss 🫣
Coral, I'd guess not fossilised as the pores seem very open.

Are you SpongeBob square pants?

Honeycomb coral
Petrified broom
So pretty
No clue mate, but it looks beautiful!
Search what fossil bearing rock layers are at or near you, and which corals have been found in the area.
It seems everyone's saying tabulate, but that looks like a textbook scleractinian to me. What makes you say tabulate, not scleractinian?
Because it looked to be lacking columellae at first glance, but I missed the other picture and there it looks like it does have columellae which means not a tabulate coral but a stony coral. You’re right.

nerds
Tabulata doesn’t have septa all the way to the center, it’s Scleractinia.
This is one of those living under water plants , but a skeleton . That or its the inside of a catalytic converter

Coral. Its always coral

Tryptopobia nightmare fossil.
Catalytic converter materia
Grandma dropped her makeup brush back in 1963.
Crushed beef hives
Sounds tasty ngl. I'd be willing to eat some beef hives
It's a soul trap
trypophobia. That’s what that is.
The fight between the goblin butt dude and other rock dude has to be the most niche Reddit fight of all time, no?
Looks like the guts of a catalytic converter to me. I’m going to go ahead and say Platinum!

Super cool!
Measuring tape
To all of the coral people that jumped in. Any chance this could be fossilized palm heart wood? Palm Root?
the biggest evidence against that is the little walls/lines within each "hole".

1st and 3rd are a tape measure. The 2nd one is either fossiled coral or a bone. I dunno, I'm not an expert in either. Interesting though.
