Ok another Mazon creek fossil ?

[Allenz]

Is it bone or stone?

One more

Looks like sediment stone to me. I may see a small bit of rugose coral in one of your pictures. It's definately not a "mazon creek" fossil. They're found in either siderite concretions, or in the brittle siltstone shale the concretions come out of. Technically known as the Francis Creek shale.

Did you find this in the area where Mazon Creek fossils are found?

Giving a general location of where items are found will help with identification.

Mazon Creek, apparently.

I don't think that large chunks of bone are something one normally finds there. In any case, this does not resemble bone.

Looks like limestone.

Ya found in private fishing club that were coal mines now spring feed lakes in braiwood

Lol duh...I read the subject title and still spaced out. This is just further evidence that I'm useless on Sundays. Lol

sorry should have said Mazon creek area

As Rob mentioned above the kinds of fossils found in the Mazon Creek deposits tend to be found inside siderite nodules and can either be terrestrial (largely plant material--ferns, etc.) from the Braidwood Biota or the shallow marine fossils (jellies, shrimp, fishes, etc.) from the Essex Biota. Unlike the more recent fossil deposits like you might find in the Peace River down here in Florida, I don't there there were large terrestrial animals 300 million years ago to leave behind big chunks of bone.

I'd suggest joining ESCONI (Earth Science Club of Northern Illinois) as they have a field trip to the Mazon Creek area later this month. It would be a great way of leaning about the fossils that can be found in the Mazon Creek area. Here is their website so you can see more information about their trip on May 21-22, 2016.

Thanks Ken

Been going out and lived in Wilmington for 30 years have many of the plant fossils, looking more into old coal mines believe the layers they dug out will produce some good finds. Ffind these all day want somthing bigger and believe I will.

Ah, I see. You already have a decent collection of ferns and jellyfish from Mazon Creek and are now trying to expand your collection beyond the "normal" finds. It seems that in your efforts to find something more unusual from the Mazon Creek area that you have overshot the runway a bit as many of your finds you have posted recently seem to be no more than suggestively shaped non-fossils. Unless you are attempting to find fossils from more recent time periods I don't think you are going to find things much bigger than maybe a Tully Monster or possibly a larger piece of a lycopsid or possibly a larger fern frond. If you don't already have the Mazon Creek Flora and Fauna books I'd encourage you to pick those up and study them. Those books have excellent photographs and information and are very useful in giving you an idea as to what you might find in the Mazon Creek fossil beds.

Cheers.

Thanks again Ken oh ya lots of info on them,Don't get me wrong still will pick up a really good flora fossil when I come across,but Intresting to see what's in layers they dug out in the coal mines.the best part every time it rains see something different.
