Can someone explain to me what a blastoid is? Britannica was absolutely useless and so I turned to here for a better explanation. Are they related to crinoids in any way?

Love the 1st one.  Is it a Deltablastus?

They are lovely specimens. :wub:

You can clearly see the petaloid food-grooves. 

These are called ambulacrum and had tiny filaments that brought microscopic food up to the mouth which is the sort of star shaped bit in the centre of the top. The five holes around it are, in four cases, hydrospires, for respiration, and the biggest one is the anus.
