Not a seed - these are sea urchin spines. This is a sea urchin with attached spines from the Cretaceous,

Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC).

I agree. Those are cidaroid spines, like the ones from here .

" In most Portuguese Late Jurassic localities yielding coloured echinid spines, only a few coloured specimens occur among hundreds of colourless spines. "

 

" In the regular echinids Pseudocidaris lusitanica and P. spinosa, coloured blotches occur all over the clubshaped spines. In these organisms, colouration may have been effective as camouflage. "

Yes, cidaroid spines, they sometimes call these ones 'clubs'. 

I have some Moroccan ones, similar.
