Dorsal view again. Some of these nodules are hollow in the center, leaving the fossil suspended in the open space:

A body missing head and tail:

It's really too bad this nodule was found incomplete:

Wow! Excellent collection.

I've done my share of Mazon Creek collecting, and have seen papers on the nodules of MO/KS/OK, but have only seen a few of the fossils themselves, and mostly here on TFF.

Thanks for sharing (I'd love to see more)!

I had no idea that the Eurypterids ranged up into the Pennsylvanian. Very cool fossils!

Thanks all for the comments.

I didn't find them myself, but I was able to obtain many nodules soon after the site was discovered.

Eurypterids can be found throughout the Pennsylvanian. For some reason, these fossil-bearing siderite concretions tend to be limited to the mid-Penn Demoinesian. As eurypterids are mostly non-marine, I figure that any plant-bearing deposit has the potential of producing one or more (though they would be frustratingly rare).
