Something from Antwerp

[ptychodus]

Hello,

I have found this fossil in Hoevenen Antwerp.
Can you help me to identify.

Greetings
Michel

It looks like some kind of limpet to me but i am not expert. So if anybody knows i am wrong please correct me.

From these pictures, it looks to me like dibunophyllum, it is a type of coral. But I'd love to see it from some more angles! 8)

The first picture looks like the inner structure of a shark vertebrate that has split in half. The second picture looks like something totally different. But I would say its a split shark vertebrate.

I am not quit sure, but you find these concretions a lot, in Antwerp, sometimes there is a little stick inside, i think a heard someone say that the concretion is formed around a rayspine, but i've not seen that, the concretions are like 8 cm long, and 5 cm wide. And inside there is this colouring you have. They also split easely horizontally.

Here a picture of what i believe it to be: a fossil limpet, althoug i have no idea what spieces this might be.

It is not easy to identify only by looking at pictures. Me thinks, a fish vertebra in a phosphorite concretion; the other side shows phosphorite with some inprints of shells.

I mean, seriously?
I fail to see how these guesses contribute anything to help the topicstarter to identify his fossil.
I'm not sure I'm even able to find things more different than a limpet, a rugose coral, a split shark vertebra and a fosforite concretion. Hold on, a paleozoïc coral. In Antwerp? The front resembles a vertebra and the back does not, so let's forget about the back and call it a vertebra, ok?

Come on.
Sorry for this rant, but I'm laughing my ass of here.

But it is not funny. Ptychodus is asking a honest question and it is turned into a guessing game. But: either you know what this object is (or you have a good hypothesis), or you don't. Ptychodus asks for help. A guess based on superficial resemblance does not count as "help", in fact, it is the opposite of help. At least, that is my humble opinion.

Anyway, I think it's the petrified eyeball of a sea cow:

Sure looks like it

Ptychodus,
Doubt if it is a vertebrae.

Haven't read an answer, it's in Dutch, it comes to regular finds, with some theories.

Hello,

thank you for your answers. I have one more picture. May be that this can give some new information for identification. Its very interesting to hear some different ideas.

I think it is a part of a vertebra, may be shark. It seams to be the best declaration.
I don't think that it is a coral or a limped because there is no coral or limped structure.
