Cant figure out what's embedded in this rock. Anybody know? The 3rd Pic is of a different rock found in the same area with a similar pattern on it. Found in Riley Co, KS - Flint hills

I've been trying to narrow down the ID for bryozoans I've been finding. I'm not sure if they're weathering out of the Bennett shale or from further up. I have collected about 15 of these over the years and found a nice one several days ago. They are characterized by rounded form with flattish uneven bases. Spacing between monticules is about 1 cm regardless of specimen size. The below example is about 8 cm wide at base and 5 cm tall. I can't find it right now so can only show photos. I'll put a link below to my more recent find. All help appreciated!

I found this weathered out near creek. Upper Pennsylvanian, Eastern Flint Hills, Kansas. Fish parts??

Found this on a gravel bar just below boundary to Permian but not sure about source. I had some trouble getting focused photo of edges. I'm thinking possibly algae.

Cottowood Mbr, Beattie Fm, Council Grove group, Permian. Western Greenwood County, Flint Hills, Kansas. I've found 6 of these in only in this one place. They are most likely the interior molds of the actual trace. They were discovered over a period of several months. They were found as tumbled out, not in situ. I'm inferring what's top and bottom due to some obvious features and basic physics. Some retain what appears to be an original edge around the top. The top diameters range in size from 5" to 10+", with heights from 2" to 6". These were found in an area disturbed by oilfield work where it looks bulldozed out for some purpose. Geologically, the area may have intermittently been shallow or shoreline. I've done an amateur's inventory of fossils in the immediate area and found highest numbers are of very! small bivalves.

I found this in creek below Permian/Carboniferous boundary. I've not seen anything like it before and was wondering if it might be an algae.

These are the most numerous former inhabitants(that can be seen with naked eye) in an area I'm studying. Cottonwood Fm, lower Permian, Flint Hills Kansas. There's an odd feature at the anterior end that may help ID it. Would these indicate shallow water environment?

We went hunting by a cliffside here in Manhattan, KS and picked up this chunk of Permian hash that had washed out and was partly covered in mud. The matrix looks similar to an earlier find from that location. I cleaned it up a bit, but I'm not sure what this wedge-shaped thing in the second photo is. Scale in first photo is in inches.

While driving from Topeka to Manhattan on the I-70 this week, we stopped at exit 316 (Deep Creek Rd) to look at exposed cliffs on the roadside north of I-70 there (Mineral Springs Rd). Immediately off the westbound exit ramp, we discovered a large parking lot surrounded by several enormous piles of rock. There were a huge variety of different fossil-bearing shales and limestones in them and the nearby cliffs, including some small but extremely rich pieces. One of them has a lot of crinoid bits and some kind of long, thin pieces, along with a major inclusion I can't identify. You can see it on the bottom left in the first photo. It's triangular and rounded and appears to be symmetrical, with a faint pattern on the surface of the central part. There appear to be two triangular indentations or openings on both sides of the central part. One small slit is visible on the exposed right side, it doesn't run all the way down. The general shape reminds me of a trilobite head but it doesn't have eye bumps and seems to be all one piece. I haven't been able to find anything that looks like this. Also, what are the long, thin fragments?

We moved to Manhattan, Kansas two years ago but I never tried looking for fossils in the area until last week. This is in the Flint Hills area so lots of Permian shale and limestone everywhere. We visited a 20-foot cliff behind the Manhattan Aquarium Co building at the southeast edge of town, and picked up a lot of loose sheets and blocks of bearing lots of fusinilids and brachiopods. We found an interesting chunk resting halfway up the cliff with large curved pieces which I was pretty excited about since it looks like bone at a glance, but they might be bryozoan colonies since they're too evenly covered in tiny pores (we did find clam shells that had similar colonies on their surface but it was patchier). There's a small object (shown first by the quarter) in the same matrix almost completely exposed. It looks symmetrical along a center axis but has a strange indentation in the middle, with the sides actually folded in and what appear to be seams. It seems too complex to be a brachiopod shell. A nice find from lower down was an extremely rich matrix with a lot of shells, fusilinids, and crinoid bits. There's a dark object near the corner that looks like part of a trilobite? There's another object in this I can't identify, shown in the last two photos above the Y-shaped bryozoan piece. It consists of a straight stick with regularly spaced branches or openings on both sides. It could be a cross section of a spiral but I would expect the sides to be offset from each other more. I'm not sure if it's attached to the flat piece at one end.

Yesterday the weather was unseasonably nice, and I had a little time while traveling through the flint hills of Kansas to do a little fossil hunting with my youngest daughter. I was hoping to get over to hunt in the KC area, but didn't make it that far. (Sorry Bullsnake) We hunted a small exposure of a grey exposure made almost entirely of fossils. Maily millions of tiny fusulinids. I also found a few plates from spiny urchins, crinoid pieces, brachs, and some other stuff. (I'm very poor on my knowledge of the Permian of Kansas.) Anyways here are a few pictures of our hunt. I find the two things at the bottom of the penny to be kind of exciting. I have no idea what they are, but they look cool! Any help on an ID of these things would be appreciated. Ramo (I also added a cool picture of a small T-Rex I came across here the other day hunting my local cretaceous rocks. I had a nice find that day, but an waiting on some further prep to revel what I brought home that day.)
