Orthoceras

40 lb. Moroccan Plate
110 lb. Moroccan Plate

Orthoceras
Sculpture
The Orthoceras is very similar to the
ammonite,
only it has a straight
shell. The word Orthoceras
means “straight horn” and refers
to
its shape. They are also referred to as
the
original
squid. They are some of the oldest
known fossils to man from
300to 500 million
years
old. The group of cephalopods called
Orthoceratoids had straight to
slightly curved
external shells, which are common
fossils in
Paleozoic rock. The Orthoceras from Morocco
occur as white fossil in a dark gray or black
marble matrix and also in a brown marble matrix.
The result is a fossil with very good contrast. |
