Good afternoon to everyone of my dear and beloved TFF! My sister bought these strange rocks in Brazil that seem to be a fragile sandstone. So fragile that it can get extremely brittle in contact with water. And in this red sandstone is inlaid a strange blue mineral, which seems rust, I do not know, but it is very beautiful! Can someone help me with the ID? I thank you for all the opinions!

I'm wondering if this is a fossilized bone or just an odd rock I found in the Oquirrh Mountains in Utah? It has a unique convex and concave surface pattern in some areas. The red and white parts of the rock have different textures; the white is very rigid and rough. All the pictures are of the same rock at differing angles. Please share your ideas, thanks!

Does anyone know what this is ?

Hi, I have no clue on this one. I was out on private land near Jordan MT. I found this rock which is unlike any other in the area. I spent two days on the property and found nothing else even remotely close to this. The land owner has had several Triceratops and Tyrannosaurus taken from his land. He didn't know what this was either. I thought it might be coprolite but I don't see any chunks of material. It looks like the core is darker with this lighter brown outside. It's relatively dense compared to most of the rocks I was picking up. It's about 7" long and 3.75" wide at base. I am thinking about cutting it. I'd be most appreciative if someone could help. Thanks!! Frank

Good afternoon to everyone. I present here one of the many strange minerals of the Brazil that I have no idea what it can be. In March of this year, I was in Brazil. I saw a great ravine of red earth, and it was in this ravine that I encountered this strange rock. This rock has a velvety appearance and crumbled easily when washed. All I know is that this ravine of red earth is quite rich in quartz, so much so that it was precisely in this ravine of red earth that I also found this strange amethyst: I thank you for all the help in identification. Thank you!

Hello, I'm new to this site and I don't know much about fossils. I have searched some trying to figure out what this rock is but have found nothing quite like it. If anyone can help me identify this I would greatly appreciate it.

Hello! I'm from Brazil, South America, and live by a beach. I like to walk around the rocks since there are lots of different rocks, and if i start to climb, the "grassy" area is full of sedimentary rocks. I've found this stone, dropped it, it didn't broke in half like other stones do, it released some type of shell (there are 3 pieces on the photos) and showed something like a "inner stone". I know that it's probably nothing since i don't know much about rocks and fossils, but who knows. I never found other rock with this "double layer" here. Thanks for your time!

Is this a fossil or just a rock it just looks odd to me but I have no experience with fossils so I'm not sure it's probably just a rock

Hello, I’m hoping someone will let me know if this rock has some type of fossil in it? I found it in a creek in middle Tennessee. After cleaning it with vinegar and water, several little black spots became visible. Are those fossil imprints of some sort?

Hello, I’m hoping someone can let me know what caused the three indentations in this rock? Weathering? Some type of track? Something previously embedded in the rock?

A place in the world where you can find the weirdest rocks on the planet? I would say it's Brazil! Here is an example of this, and I have no idea what this might be, but I assure you, it is very heavy. Anyone know what this might be? I appreciate all the opinions and helps. Thank you!

Hi I was recently doing some planting when I came across this thing. Does anyone know what it could be? Our house was built in 1800 and this was located close to the stonewall that borders our property.

Good evening to all! I have already said that the most bizarre minerals from around the planet can be found in Brazil? This is another bizarre rock that was discovered in Brazil. I do not know what it is, but this black rock, I suspect it's basalt. Could it be basalt? But what struck me was this strange, very bright incrustation that looks like molten quartz ... Sorry for that expression, but as I said on previous topics, I do not understand anything about minerals, and I'm starting my collection now. Thanks for the help and opinions.

Hello my friends. Good evening! This strange rock came from Brazil. I had to wet it, otherwise the smaller details could not be visible. But it's a very beautiful rock. Any idea what that might be? Green quartz? As always, I thank you for all your help! Please my friends; @ynot and @DPS Ammonite

Hey guys! I hardly know a thing about fossils and it would be great if someone could help me out. My family and I visited Chippoke State Park and found what appears to be either a fossil or just a shell trapped in sand. It’s about 3 and a half inches wide and long. Anything helps. Thanks!

Hello, I have a rather large rock in my yard (middle Tennessee) which I have always thought was interesting. I’m hoping somebody will let me know which type(s) of rock it is? It has gray and white crystals(?) of some sort on top, along with white streaks running through it. It also has several knobby areas. Are these chert nodules? Any information is appreciated. Thanks!
-
I’m hoping someone can tell me if this is a paw track of some sort? There are three indentations on this rock of very similar shape and size. (four inches wide) Or would it have been impossible for this type of rock to have had any tyoe of tracks? The rock was in my barn in middle Tennessee. Thanks.

I was walking on the beach in Cape Charles, VA and both of these ‘rocks’ turned up in the surf together. I feel like they may be fossils but I am not sure so I am turning to you experts ;-) If they are not fossils then are they bone or just very strange rocks?!? Thank you!!
-
I’m hoping someone will let me know if this is “just” a rock, or possibly a coprolite of some sort? It seems to have different textures and layers. Thanks!
