From the album Dinosaurs & flying reptiles
Another view showing an area of what I do not know. I'm guessing it involves nerve fibers/channels. -

Another view showing more channels/cross sections of blood flow(the small solid dark gray areas), and nerve channels. I'm not entirely sure what the large dark areas are, although I believe it to be related to blood flow as well. -

2 pieces of a triceratops skull with brain case impression. Blood vessels, veins, and arteries visible, as well as nerve channels. I have to contact in order to get the fossil information again. -
How could this possibly happen??? How would they eyes be so dark while the rest is barely visible? And not just that, how are the eyes just the silhouettes, and not solid? It's not like they were made of anything different, or different in any other way. They couldn't be have been fossilized in different ways. is this possibly genuine??? I totally trust this persons other stuff, this one just seems so impossible to me. -
This "river rock" came from a bag purchased at a home center in Illinois so the place it was originally found is unknowable. Can someone help me identify this, please? It is a cylindrical impression of something with rings. In my mind's eye I'm seeing a plant stem or reed of some sort buried in mud near a stream or pond, but I'm virtually clueless about these things and would appreciate it is a more knowledgeable kind soul would offer a more informed opinion! Is it plant? Animal? Insect? Approximate age? Thank you!

Just an ID, please, there's a lot going on in this piece.

I'm getting braver and will venture that there is at least one crinoid columnal mold preserved in this formation. I'm fairly certain, however, that the other two most prominent molds are not of a crinoid. How am I doing?
-
I now understand that these are likely molds, but of what I don't know. I am learning a great deal, though, and am so glad to have found this place!
-
I'm not sure if this is an impression or trace fossil, so educate me on the difference please, but it's definitely something. I enhanced the color only slightly so y'all can see it better.

I have two Triassic coprolites from the Bull Canyon Formation, Quay County, NM. The first one has an impression/imprint that I have not been able to identify. The second has a protrusion sticking out of it. I had hoped that by prepping out the the protrusion, I would get lucky and it would match up with the marks on the other. Unfortunately, I now have two things that I can't identify. @Carl 1. Is there anyone out there that wants to take a stab at identifying the imprint in this one? It does appear that there are some remnants (white) of whatever it was that made the marks.

It's located here in Alberta, Canada, but I can't say for sure this is where it came from. It's been passed down a few generations, but has essentially been sitting in a flower bed for the past 40+ years. I really know nothing about it.

Here's a piece of shale I found near Pueblo, CO. The formation comes from the Western Interior Seaway of the Upper Cretaceous. The raised striations lead be to believe this could be an impression of a marine organism, or just a psuedofossil. Any help with the ID would be amazing. Thank you! - Geoff P.S. the measurement units are inches

Asking the forum for their expert opinions on this find from today in NNW San Antonio in a creek bed. Thank you.

Hello, My brother was recently digging in the stream nearby his house, upstate New York, looking for some nice rocks to put in his yard, and have found this piece, which he later gave to me. There are many impressions of some kind of Brachiopods on it. My guess is they are Pennsylvanian period Brachiopods. Am I right? Thanks! Diana
