It was just a handy picture of a similar looking coral - but if you were to look at the sides of it you could see it extends downwards where a surface encrusting bryozoan wouldn't.

Favosites sp. - coral.
 

Edit. at 20x Magnification.

 

The way to tell would be to check the sides - if its a coral i would expect the clusters to extend downwards so you'd see lines going down.
