i found an auction for "cretaceous reef aquarium foundation live rock". has anyone ever heard of using this stuff? it says that it
"comes from the Cretaceous Great Barrier Reef in Central Texas and has been above ground for more than 100 million years. In the Cretaceous the shallow warm water reef spread from Texas to the tip of Florida, over one thousand miles, and hosted a variety of marine life similar to the life expected in modern coral reefs. Identifiable fossils found within the rocks include rudists, algae, sponges, bryozoans, brachiopods, crinoids, conodonts, coral, ostracodes, gastropods, nautiloids, and other forms of marine life."
it is pretty cost effective and shipping is pretty cheap too, but i dont want to buy some rock that is going to pollute my tank. i know that it is not live rock but i have 100 lbs of lr in my tank already so it will get seeded eventually.
any thoughts?

The rock is AT LEAST 100 million years old. Back then corals didn't make skeletons out of aragonite, as they do today. They made skeletons out of calcite, another kind of calcium carbonate. Any live rock you buy from a reputable source will be made of aragonite, which is required to keep corals in captivity.

Why would you want FOSSILS of all that stuff, when FOSSILS are not known for their filtration abilities?
BTW, Blaze, I don't want to sound like I'm criticizing you. I just think the ad is hilarious.

its all good. ive got thick skin. this is why i post on this site because i get answers.
also, they arent really stating that it is live rock, they are just stating that it is used for base rock that could be turned into live rock.

This is a fancy pants description of standard holey limestone baserock.
that is all it is...and a lot of it comes from Texas.
You should be able to get a picture.
But otherwise it is not deceptive.

It's Texas holey rock. I got some in my tank. It's fine. And it comes in all kinds of shapes and sizes. I also got rock from florida that was dug up from the ground. It's all limestone based rock. It also has some really cool fossils. Just mix with some regular live rock and it will be fine

That's exactley what they do in florida. Dig this rock up from construction sites or whatever, throw it in the gulf, and a year later you got live rock.

I know what your looking at isn't pulled out the gulf but its the base rock they dumped in the gulf to make aquacultured florida live rock. I watched a video from the company that put it there. showed the whole process from several years back with the big barges and cranes they used to dump it in the gulf and then showed it years later after the inhabitants had took to it=aquacultured florida live rock.

There is a difference between Texas Holey and this rock.
This Cretaceous Great Barrier Reef in Central Texas is Tufa Rock
"Tufa is the name for a form of calcite rock.
Tufa is a calcium carbonate (CaCO3) deposit that forms by chemical precipitation from bodies of water with a high dissolved calcium content."
Texas Holey is basically the same makeup but is dense and and heavy ,Tufa is porous and light.
Tufa:

Texas Holey:
