A "replica" of a rare Moroccan trilobite. Very good completeness. Incredible how they can reproduce
these intricate trilobites with a good likeness to the real ones. Yes, these masterpieces are fakes, but it
is a very well done replica of a rare trilobite species. This is a very affordable specimen of a rare
Moroccan trilobite species

Dicranurus monstrosus - a horned trilobite (Morocco)
Dicranurus (Order Lichida, Family Odontopleuridae) has one of the most bizarre morphologies of the
trilobites coming from the Lower Devonian of Morocco. Most notable are the pair of swirling spines
resembling horns that are attached to the occipital ring. The trilobite is both rare and quite difficult to
prepare, at least with crude tools. Both are reasons that authentic specimens are expensive and
frequently found as manmade specimens. The Moroccan manmade pieces are really quite a work of art
and are often mis-represented as genuine trilobites. There are many manmade specimens used in
educational and private displays that have too much activity for genuine museum pieces.
When the matrix (or resin in the case of manmade) inside the horns has not been removed and when
the matrix is a light brown color and the exoskeleton a is brown (rather than normal black being), then
suspicion should be heightened that the trilobite is manmade. Dicranurus trilobites, like other trilobites,
are most often made by casting in resin or plaster both the trilobite and the underneath matrix layer, with
both ultimately placed in a hollowed out, piece of real matrix limestone. This is often referred to as the
typical "imitated-matrix-fake". Genuine Dicranurus trilobites are normally prepared with free-standing
horns, because the extra effort is warranted by the trilobites rarity.
To what purpose could this spiny exoskeleton have been evolved? The answer is simple …Self
Defense! Fish had recently evolved jaws, and in the never ending evolutionary race between predator
and prey, Dicranurus' answer was a spectacular defensive array of spines.

Odontochile spinifera

This Moroccan Trilobite is also an amazing reproduction done much the same way as listed above.See
our listings below! Beautiful workmanship! If these were real they would sell for mid hundreds to
thousands of dollars each! We decided to bring you some affordable representations instead of
genuine "way too costly" specimens...Enjoy...
