The original page only had picture #1 seeking identification of this ammonoid.
Mark McKinzie replied: That
has all the makings of a Domatoceras nautiloid (NOT an ammonoid). However,
to be sure another picture needs to be taken of the keel (outer rim) as it
should be flat and possibly starting to develop a scalloped edge on both sides
towards the outer (aperatural) end if it is a mature specimen. Any shell ornamentation
should consist of very fine (faint) growth lines. Big ones are commonly flattened
from the Pennsylvanian Mid-continent region.

Later...Pictures 2 and 3 were added.
Mark's observations were correct and the specimen
is in fact the nautiloid: Domatoceras
sp.
