Hi, I'm new here and just wondered if anyone has an idea of what this is? I have no knowledge in this field as this is not my area of science. I just thought it would be interesting to find out what I have stumbled upon. Thank you in advance.

After walking 2+ years by the same spot, just noticed this, yesterday. It sparked an interest, but I know absolutely nothing about fossils. Is this a normal size for what I think is an ammonite? Found in Northwest Austin, Texas near the bank of Walnut Creek. I am assuming it’s limestone. Grandfather’s hammer is 37 cm.

Found this on a Lake Champlain beach, looks like a fern but any info would be great!

My son found this in a load of river rock from the Arkansas River in the Fort Smith area of Arkansas. Any help with ID would be greatly appreciated.

You guys sick of my threads yet? Sorry, there’s a lot more to come. Here is an interesting surface which features may be purely natural erosion or a fossil imprint. Coral maybe? Almost looks like fossil rain drops, eh? Any clue if it’s organic in origin? From northern Illinois.

I am new to this so excuse my lack of terminology. I am looking for help identifying what this is. I picked it up next to a excavation sight that I have pulled hundreds of bones from. I have also found many primitive stone tools in the same location. I found what appeared to be a primitive tool. Upon closer examination I have discovered the top half covered in a leather like impression. I am not certain that this is a tool, or a bone but I am under the assumption that this is a impression of skin on this object. Any information will be helpful. I will be posting pictures of the amazing bones I have collected in hopes of identifying what dinosaur I have. This was collected in the north Saskatchewan river, just off of the shore.

Howdy. Found this in Central NJ. Is this a real fossil? Anyone know the type? Thanks

Could this be a tree imprint? Or incect? Or just nothing ?

Hi I was wondering if this footprint looks legit to everyone. It's allegedly a imprint and outprint of a Anchisauripus. I won it in a auction but I don't have it in hand yet so these are the best photos I have at the moment. Does it look like the real deal or should I be concerned? Thanks for any help

My daughter found this in a stream on a mountain in the North Cascades (Skagit county). Is it an imprint of a leaf?

I found this while floating the James today beneath the sand in the shallows, the rock is smooth for the most part except for this side. Definite rows of "legs", could it be a coincidence? I'm on the fence about this one, would love insight

Cretaceous, Eagle Ford. I'm curious because to me, it's very similar to the imprint on the crab carapace found in the same area on the same day:

I live in Utah, which I have heard is a hot bed for Fossils. I love to collect rocks, but I don't really know anything about fossils. I was at a cabin a while ago and found this rock on the ground. The cabin was in Weber canyon (Trying to be specific for forum rules) and it was found relatively near a river. The rock has a perfectly shaped oval, egg shaped imprint on it. I don't know if its an egg but I't going to refer to it as the "egg imprint". As you can see the outline of the egg is dark, and then the inside is a lighter brown. The rock is really hard but the place where the actual egg imprint The rock is a different material that isn't as hard and has a more grainy feel to it. The rock itself is very interesting besides the egg imprint. It was very unique patters in it all around that I've never seen before in a rock. It looks like something that would have a fossil in it, something really old (but lets be honest I have no idea). In terms of weight, the rock is lighter than it looks. It's not exactly light by any means, but actually feels lighter that you would think it would be. Also if your looking at if from the side it is different colored at the top where the imprint is. Its almost as if someone painted the top. It appears to me that maybe that was a layer of mud or something? Due to the VERY annoying image size constraint on the forum I could barely show any of the rock but i did my best to show you what i was talking about. this is the imprint itself. The egg is about a inch and a half by an inch (not very big) this is another view of the imprint with the side showing where it starts to get lighter (so frustrated i couldn't show more) this is what the backside looks like (cool rock patterns all over) and this is just a closer view at part of the imprint itself My guess is that this is some type of bird egg that fell into the mud and then fossilized. But maybe it isn't anything at all, but I've been obsessively perplexed with it and I would love for someone to share their knowledge and opinion with me. thanks!!
