More pictures from different angles might help. click on you post and edit specimen, then you can add more. My first thought is ammonite, but the section at the bottom of the picture looks like it goes in a different direction from the rest, which I don’t know of any ammonite like that.

second picture is bryozoan, first picture might be chain coral

right side might be internal cast of a crinoid. there’s a technical name for it but I can’t remember. top might be a shell imprint, but it is pretty worn.

Use macrostrat.org, put in the place names, and enable fossils. you’ll get blue dots telling what has been recorded.

Use macrostrat.org and put where you found it in. it will tell you the age of the area, so you can see if dino is a possibility. @mason-hintermeister might be able to help. great find though eleven if not dino, the preservation is fantastic.

The fossil is out of focus but it looks like a “plant” orthoceras usually from Morocco. There are folks who toss fun rocks/fossils in rockhounding areas to either brighten someone’s day or confound the locals, depending on your pov.

I know admin would rather you did not, each entry gets logged as a fossil specimen for possible research and it’s a lot of time to clean up. There are a lot of rock id groups around, many of them location-specific so you are more likely to get a more accurate answer.

Septarian nodule.

Fish makes sense. I mostly picked stuff up and handed it to the grad students to interpret.

Again I’m inclined to say champsosaur, but I’m out of town and my reference guide is at home.

I don’t know the area but the cretaceous I worked had a lot of champsasaur, their vertebrae had similar hourglass shapes. But I’m not very confident that is what these are. The black one looks like something else entirely

looks like the dental plate from a ray.

Looks like a trilobite pygidium, some shells, and possibly smaller trilos. I can’t get detail on the small black spots, but they look like they might be something.

I agree it’s a coral.

@mason-hintermeister thank you. I was leaning whale, but not much experience with macro fossils. Unfortunately I have no location data, it’s from a poorly managed estate collection.

Macrostrat shows the area as Pliocene to pleistocene. You might be able to Google Pliocene shark teeth Florida and start identifying some on your own. Fossilguy.com has good guides for peace river and Venice beach, both of which can have fossils of the same age. Fossilguy also suggests a book: Florida Fossil Shark Teeth Identification Guide.

@aiden-gore-3 rare depends on where you are. Shark teeth are rare where I am, but plentiful where you are. Different countries also have different laws around fossil ownership and Sales. Generally in the USA vertebrate fossils found on state or federal land belong to the state itself, which is why they go to museums. Other countries don’t have or…[Read more]
