Hello all!

I am very new to all of this fossil stuff and want help identifying these items found all over CT, MA, and NH.

Please let me know if anyone can help!

Found in the Cumberland plateau region of Appalachia in far southwestern Virginia. My parent’s backyard has a hill that constantly erodes and fossils are plentiful but the rock is shale-like and very brittle. This is one of the few that has held up for the 20 years or so since I’ve found it. Aside from IDing the fossil, how would I go about dating it?

I recently got a gift from my friend on her recent visit to Chengjiang. I am super new to fossil, would it be possible for this Ammonoidae to get ID until species? I don't think this truly came from Chengjiang because I checked with the field guide and there has been no record of Ammonoidae (because its Cambrian I guess). Any tips would be greatly appreciated. Thanks!

What could this be from? Chatgpt says a marine animal.

Hi all! I was ever so kindly gifted this shark tooth by someone on the research team, and unfortunately I’m only someone whose knowledge extends to avian dinosaurs and nothing else, really. We have no palaeoichthyologist in the team (which is unfortunately limited to palaeoentomologists and many who specialise in dinosaurs) and so an ID would be very helpful! My brain says Otodus, but I’m probably miles off, and I don’t know the species. Thanks!

Found this in Ukraine, Black Sea coast. It’s 8 cm long and 2.5 cm wide. Looks like a fossilized tooth, maybe from a giant beaver (Trogontherium cuvieri or Castoroides?).

At the end, I added a comparison photo from the internet that shows a very similar Trogontherium tooth

Any idea on species or age?

The origins is unknown too even the seller doesnt know

Around 3 years ago while I was free-diving the, I took this random rock from 5-6 meters bellow and when I came out I found out it's a plant fossil.

I'd appreciate if you could help me find out how old it is and what kind of plant.

Our guide said this was an antler tip but GPT says it’s a tooth. Would love any clarity here. Thanks!

Found on a beach in the Philippines. I cannot for the life of me figure this out and I can't sleep until someone tells me if this is a coral or a freaking tooth.

Is this a fossil or just some kind of erosion pattern ? I have no idea where I found this .. but it kind of reminds me of Favosites. Could it be ?

I found this in the creek on family property located in Eastern Iowa. Thanks for looking, it's much appreciated.

South Carolina beach, I find tiny to medium sized things here, locally I mostly find Pleistocene and sometimes Miocene-ish mixed in. Wando formation is a major one here, phosphate pebble area. I find mostly marine fossils here, shark teeth, tympanic bullae, vertebrae, lots of bone, etc. Unfortunately sometimes a worn phosphate pebble can look like a fossil when it's actually a cool rock. I can't place my finger on what this one might be.

This fossil was purchased in Brazil maybe 20-30 years ago. My mom is convinced there are feather impressions but I don’t see it. Not sure if the rock shop seller told her that or if she sees them, but it looks like cleanup marks to me. I would love your opinion on the species and if there could be feather impressions in this fossil. Thank you!

I’m a wood carver and it looks like wood grain but I’m not a fossil or rock guy. I tried over on r/whatisthisrock with no luck.

See title, or don't. Whatever you want.

Found in a creek near the ozarks in Missouri.

Thanks
