I'm stuck in a library; what book should I read?

Examples of Weird Paleozoic creatures

Pulled from sections of saved files, papers, or archived websites in my file cache if I have a working current link I'll put it up.

An extinct echinoderm with a body
composed of many plates, and thin, ambulacra-bearing "arms" for food
collection. Most common in the Early Cambrian. Genus _Gogia_.
This morphology is intermediate between the "bag-like" morphology
of some early free-living echinoderms (the helicoplacoids), and later
crinoids. However, they probably represent an independent group that diverged from the crinoid lineage, rather than an ancestor. 1.7X. [(3), p.587]

Silurian to Devonarian period a giant fungus "tree"

If more is necessary I'll post later when I have access the the full collection rather than just what was on my jumpdrive.
