[Rockhounds] fossil corals

[Rik Hill]

Hi Alan,

These are Devonian, though the dealer did not tell me I could tell with 
a quick look. They are very like the corals I have collected in the 
Silica Shale, Ohio/Michigan and Widder and Hungry Hollow formations in 
Canada.  I know I could get to genera, but I wondered if anyone posted 
any work done on these.
