Does  anyone know where I can get a copy of "Cenozoic giant pectinids  from
California and the Tertiary Caribbean Province: Lyropecten,  "Macrochlamis",
Vertipecten, and Nodipecten species,"  a U.S.  Geological Survey publication
(or
how I contact them for a  copy)?   I am trying to determine whether Nodipecten
nodosus is  an extant species.   I have been calling our non-fossil Lion's
Paws
"Nodipecten fragosus."   But apparently nodosus was at least  a fossil
species.
Maybe Bret Raines or Carole Marshall can at least  straighten me out as to
whether both fragosus and nodusus exist today and  the differences between
them.

Thanks!



Dear Linda,
 There are both species, fragosus and nodosus living today. According  to
Smith, the normal habitat of fragosus is the W. coast of FLorida and the
panhandle to at least the Dry Tortugas. nodosus is the species living on the  east
side of the Yucatan Peninsula and along the coast of South America. (See my
American Conchologist articles of March and September 1995. There is a good
explanation of the two species in that). I don't want to confuse the issue  too
much, but I feel there is another subspecies on the east coast of FLorida  named
by Kuster and Kobelt, but we won't go there right now.
  There is evidence that the two species are found in fossil form, but  there
are also other fossil species of Nodipectens that have other names.
