Also known as Savannah River agate.19 named bryozoans fossilized in this material.Snails,shells and other stuff too.Was a favorite knapping material by ancient man.Many have colors effected by heat treatment.Forest fires also heat treat surface material.Can break 2-300 pieces of some grades of this material with the heat of a magnifying glass focusing sun light in one little spot.Bryozoans are also called New York sewer monsters in this age.They may be edible... www.flickr.com/photos/67205364@N06/sets/72157632569773602/Attachments:

The savannah river agate will change.If it is yello,orang or brown it should look like a dark brick and polish worse.It is better at 400.

savannah river agate can be boring Tammy.You westerners stole all our colors and put them in your agates.Most of the color in those were put in there by heating(cheating):>We have to do what we have to do to get color down here in south land.A lot of us have plenty of color in our personalities and red on our neck:>We had to send Doc Holiday out there to deliver kindly southern manners:>

It's odd that when dead, something is more attractive than when alive.

That's very interesting! I was not familiar with bryzoans but saw them in another of your threads. I'm curious about them, are they found at all areas of the Savannah river including South Carolina? Do all Savannah River agate contain bryzoans fossils? How can you spot the bryzoans in the rocks? Nice thread!

Yikes! A vengeful sewer monster! Yep, better as a fossil. Prettier, too.
Where else are they found besides the Savannah River and NY sewers? I imagine any place with lots of water. Is that right?

I eat a lot of stuff. I draw the line at stuff cultures in sewers.
It is wierd that somehting with no structure could be fossilized.

shotgunner, I agree. French Dressing or not.
I think there are worm fossils; that's weird, too.

Do all Savannah River agate contain bryzoans fossils? How can you spot the bryzoans in the rocks? Nice thread! The old beach Dora,they are found at the intersection of the ancient ocean beach(known as the fall line) and the Savannah River.A chert covered location,the chert being this Savannah River agate.The main outcrop is about 20 miles in diameter called Stony Bluff right on the Savannah river.It is in about every road cut in the area.It is one of the largest indian mines in existence.I find artifacts made out of that unique material all over the south east.What is more amazing is the amount of it that has been heat treated.For miles you can find red,green,rich yellows and oranges-all those colors do not occur in the natural occuring state.Three feet down in the ground on flat areas,in the roads,most excavations-the heated stuff is everywhere.The natural stuff is kind of boring.England sent William Bartram to US to report on nature in the SE US.In like 1700.He made note of the "parti colored rocks" at Stoney Bluff.It is also known as the Mcbean Formation.I googled that and found out what bryozoans are and that the Mcbean formation had fossil examples of 19 varieties,before that there was only 8 varieties. I guess they saw the images in this material.The rind of this material has fossil replacments that may have given better molds to study the fossils with.I do not know Dora.As far as i know this chert is only in a 50 mile area.Other cherts in our area are a liitle similar though. What blasted my mind was a bryozoan.In 20 years of being in the wetland bussiness i had seen bryozoans on many occasions and never knew what they were.Mostly in polluted urban lakes-up to 3 feet around,weighing hundreds of pounds.and by the thousands.But i never knew what they were until that youtube video earlier in this thread-look at some of the other bryozoan videos and you will see them the way i always saw them-attached to a submerged limb.We used to have wars w/them when we were kids.We thought they were frog eggs.throwing them at each other,they would knock you off your feet and then make you vomit. What is also strange,is that a bryozoan is lichens-or animal-i don't think any one knows.I think some of the fossil guys on this forum have mentioned them fossilized in other parts of the country.
