Not sure if this rock is a fossil or unique mineral deposit that created uniform circles within the rock. My amateur guess would be maybe coral fossil?

Found this recently on the Dorset coast. The circles are thumb sized. Not solid rock but shale. Any ideas what caused this?

Hi all, I found this specimen while exploring the desert around Las Vegas. Does anyone know what I’m looking at?

Hey guys, I have a special creek site close to me in South Florida. it yields marine fossils of every kind and even some artifacts. I have found many pieces of dugong bone with a strange circular indentation, and I’m really hoping someone can help me out with determining what causes this? I have found fossils of a huge variety of Pliocene/Miocene marine animals, and dugong bones are the only bones with such markings. There is a raised center and an almost perfect circular depression around it.

Found this in a customer's rock garden. They had a couple truckloads of the most random assortment of rock sizes, shapes and colors I've ever seen. I apologize that there are no clues based on it's location. All the rocks in my 'hello from Oklahoma' intro were all found in the same place. They rock itself is approx. 2¼ in. long x 1¾ in. wide x ½ in. tall. The marking isn't an indentation but the 'medium' -for lack of a better description- seems organic. If it is human-made, I'd be curious to know how. The markings are so precise as to be human-made but also seem completely natural. I've not attempted to clean it, except for a damp thumb rub or 2, but it doesn't seem like it would budge. I've shown it to probably a dozen people (none of whom were rock or fossil enthusiasts) and no one has a clue. I can't wait to see what y'all think. If I'm lucky enough for this to catch someone's eye. Please let me know if I can answer anything or post other picture etc. I can't thank you enough in advance. Have a great day.

Hello guys! I would like to hear your oppinion on these circles. I was suspecting for amonites, but it could be just a Bryozoa. #1 #2 #3 #4 #5 #6 #7 #8 #9

I’ve had this mepygurus marmonti sand dollar from the Jurassic of Madagascar for years now and when I was looking at it I noticed these small circles on the bottom. Are these on every sand dollar, it appears to be a part of it so my guess was some sort of way for tiny legs to attach but it’s just a guess the sand dollar is 7.5 centimeters and each dot is just under 1 millimeter

I found these in the creek back in September, this is the only pic I took (just now happened upon it in my files) and I can't find them to retake pics. The largest rock, the black one in the right of the frame, is no bigger than 2" at it's widest measurement, if that helps. I'm just really curious about what would make these little bubble-like formations printed on a rock like this. Bubbles?
