Found this piece earlier in the year around Benbrook. Specimen is around 9" in diameter and 3" in thickness and weighs around 4 lbs. Was pink in color, but since has paled to a dull white.

Bough this long time ago and lost all information. Does anyone knows what is this? Period?

Three photos of this strange find. My son and I found this as is on a mountain trail on Fossil Ridge Mountain. I have no idea what this is, I would guess it is some sort of shelled sea creature, a little smaller than a baseball. If someone could enlighten me, my so and I would be grateful. Thanks for looking!

Do you know what this fossil is were on the body and from which dinosaur ?

Archaeopteryx

Hello. I haven't been to this site for a while, and I've been doing a lot of paleontology reading and studying. I've been through 6 or 7 books over the past couple of months that focus on different aspects of paleontology. It seems that one of the areas I'm most interested in is the Permian period, but it's really difficult to find the kind of information I'm looking for. There seems to be a swath of books at my local library covering dinosaurs, the Cambrian explosion, Mammoths, and even several books on the origin of life itself. These books fill up one and a half 8 foot tall book shelves, but there are only 2 books on the Permian period - both by the same author, and both on the same topic - the end Permian extinction. I think there may be a few other periodicals and such that are focused on the geology of the basin, but not on the time period, the fauna, the vertebrates, the predators, etc... Is there just that much of a lack of information on the Permian period (in the fossil record), or is it just that no one is very interested in it? Even Amazon searching for a book on the Permian gets very few results with mostly low rated books. I thought surely that someone would have written a book covering all those strange and interesting creatures - the Gorgonopsia, the Eryops, the Edaphosaurus, the sea creatures and so on.

Most of the time I pick up or dig sharks teeth in a creek near the Rappahannock River but I found it was mostly sanded in when I went to look. Did find a hole in the side of the creek where seashells were stacked with water flowing through, removing most of the silt (and depositing many teeth and other fossils in front of the hole). The bottom layer was hard gray clay, few if any shells. The second layer was a fragile heavy white triangular shell (or impression from a long-gone shell. Above these the shells seemed more jumbled and less distinct layers, but contained lots of very flat shells, scallops, curved oyster-like shells, a straighter oyster-like shell with distinct growth(?) sections, and lots of clams and barnacles. (One shell was partly covered by a layer of coral-- but doesn't really show in the scans). Most of the shark teeth seemed mixed in the jumbled layer. I'm curious about the fossil seashells but wonder if they can provide the era and period where the shark teeth and other fossils come from. Except for the flat shell and maybe the triangular white one, the shells don't scan well but I'm hoping some of you can recognize them despite the poor pictures. (Having trouble loading but will add others ).
