Does anyone have information about this?

To make a good identification we need a minimum of information : location of find -> state, county, nearby large city; size but only in cm or inches, age of the sediment where it was found or formation, and photos from all sides. Here it would be nice to see the bottom. I have an idea but I ask to see more.

 

And above all, according to the rules established on this forum and you could read during your registration, we are not talking about monetary value !

Not a starfish but a sea urchin, perhaps Clypeaster.

A look at the other side would be helpful. I suspect this may be the arms of one of the more unusual crinoids.

@AhmetAtes01 I moved these over from your message. Hope you don't mind. I need help with the ID.

Hi,

 

Too bad the bottom is not clear, but as Roger says, I think it’s a Clypeaster sea urchin, it’s the outer layer just under the shell we see.

Not sure the genus, bit it's definitely a sea urchin.

C. rosaceus? its the only one i could find that looks like a possible match. most Clypeaster sea urchins are usually very flat, thus the nickname Sand dollar

I do not know enough about the Clypeaster to specify the species, and especially coming from Turkey. I think if we had an age, it would be easier to determine. But I remember that it is for me an internal mold, so it lacks some features.

 

It is not what Americans call a "sand dollars" because they are very flat. Rather, it is what you call "sea biscuit".
