[Rockhounds] Civil War Tombstone

[betdav97 at aol.com]

  The tombstone was limestone, not granite, and yes,
crinoids still exist today. The common name is sea lillies.
Crinoids have been in the fossil record since Devonian
times. Alan, it was on the Paleolist forum.

Hi. As I was reading this article I wondered about the ages given for 
the
crinoids.
?Did the 220 million years mean that that species lived  that long and 
were now
extinct?
I  thought that crinoids were still around?  Anyone know what fossils 
were
identified in  "granite".smkell
