Strange fossils

[madagascar]

From Madagascar 
Probably Mesozoic 
Why is this fossil lying on its back .looks like a parrot's beak.

----------------------------------

These are some of the details that prove it's a fossil 
It's a very damaged fossil 
It preserved conical foramina, and preserved neural crest vertebrae fossils are rare in Madagascar 
So what kind of animal is this? 
Detail the rupture above the neural crest is seen to form a square inconsistency 
The fractures on the spine have detailed bone patterns 

Thank you for your answer.

---------------------------------

Thank you for your insights. 
I've seen many kinds of vertebrae from Madagascar, but this one is very special, very strange. 
But I also want to ask: why is it in this form? Like a lie? 
As I've drawn it: the red is a separate spine, the yellow is another spine; The blue one is the nerve, why is it so combined,？ what range of animals is it?

Sorry, but I wouldn't trust any seller who only shows something wrapped in plastic no matter what his claims.

Thanks for reminding me.

I'll change the picture.

This looks like limestone to me, not bone.

There is actual skeletal structure, and you can see the damage. 
And because it looks like a rock I was lucky to get it. 
But his shape is different from the common vertebrae ...

I am not an expert, but after 12 years of seeing fossil bone on the Forum, I am not seeing the texture one would expect to see of fossil bone.

Wait for other replies, but I am unconvinced that this is an actual fossil.

Looks like a badly worn vert to me based on pic 3 from the top.

I can't make up my mind. Whatever it is, it's EXTREMELY eroded. And damaged if it's a vertebra.

it bears a passing resemblence to,e.g.,an eroded Burnetia cranium

edit: resemblance
