Is this a vertebra?

[tomas]

Hi there. Im new here and im from Greece.

So once again two days ago i went for hiking in the mountain. Almost everytime i find sea urchin fossils there. (Never found anything else like a shell fossil) . However more than 4 years ago i also found a strange "rock" and luckily the last time i found an exactly same "rock" again. I really have no idea what this is. It seems like a vertebra - spondyl to me. I hope you guys can help me because im really really curious. I hope these pictures are good enough for you to find out

Looks to be Rudist bivalve fragments. Possibly Durania austinensis.

You guys are amazing Pretty quick and accurate answer. I hoped this was something of dinosaur

Im trying to find the greek word for "Rudist" with no luck yet. This species dont exists these days, am i correct?

Im sending you some pictures of the sea urchins. These are two of the best i have found. Most of them are broken or not formed well.

What else could i possibly find in this area full of urchins ?

That looks to be Echinocorys echinoid. https://www.google.com/search?q=echinolampas&biw=1360&bih=612&tbm=isch&tbo=u&source=univ&sa=X&sqi=2&ved=0ahUKEwicvrSKnKzMAhXK1xQKHVkGDBQQsAQIGw#tbm=isch&q=echinocorys+of+greece&imgrc=_

Nice finds! They are Late Cretaceous marine fossils.
