I think you need a good bryozoan book instead! :D
There's something similar to the first one called Reteporellina/Reteporella sp in Gosliner, Behrens, & Williams. The other I can't really match. There's a great assortment of identified bryozoan images by Karen Gowlett-Holmes at http://www.civgeo.rm...es/default.html

Thanks Leslie I think you are right about the first being a bryozoan

I found the second one. That one is a hydroid Aglaophenia cupressina

It is similar to an Australian species Canda arachnoides ... a key feature is the branches of the bryzoa are connected by cross tubes
