About this site and the author
This site
is
meant to be a reference to help provide information on the identity,
biostratigraphy and location of fossil cephalopods found in the state
of Utah. All fossils shown on this site were collected, or
photographed in the field, by the author. They were all found on
public land, administered by either the Bureau of Land Management
(BLM) or the United States Forest Service (USFS). Or land formerly
administered
by the BLM that is now property of the State of Utah.
Fossils shown on this site are NOT for sale or trade. I am not against the selling and trading of fossils, it's just that I choose not to participate, and abide the law. For rules pertaining to fossil collecting in Utah, see collecting rules at this UGS site.
There is no copyright on any of the pages or photographs, except for logos, photographs, or names, owned by other sites. It would be nice however, if you use some of my photographs, to mention where they come from, and link back to this site.

This site
is owned
and maintained by Kevin Bylund, shown below in the desert of
western
Utah collecting fossil cephalopods. I am an amateur
paleontologist with
an interest in cephalopods and cephalopod biostratigraphy, and
sometimes an avocational paleontologist helping local universities and
surveys in
some of their dinosaur quarries. A member of the Paleontological Society, the Palaeontological Association,
and
the Utah Friends of Paleontology.

This site was started in December 1999, and first published on the world wide web as Old Calamari with Xoom.com in February 2000. Later Xoom.com changed to NBCI.com, after a few years they stopped offering free web space so I moved the site to Topcities.com, only to have them shut down. On October 2, 2003, I registered the domain ammonoid.com, where the site is now.
