Had a large Annularia from Danville open up this past weekend. The concretion is about 4 inches across. It has a fern (Crenulopteris?) and a ghostly Lepidostrobophyllum on the outside. On the inside is a beautiful Annularia. The Danville fossils are a few million years younger than Mazon Creek, but many of the same species are present in the deposit. This concretion was collected back during the fall Danville field trip.
Enjoy!
