Fossils of Morocco North Africa

Though I never left the comforts of South Texas to shop around the world, specifically Morocco to found these awesome rocks for wire wrapping, supplied of Panther Creek Minerals of San Antonio Texas. These are natural Orthoceras a fossilized squid.

Orthoceras are a famous and very large fossil deposit of animals that can be found in Morocco, North Africa. Ancestors to ammonites, Orthoceras are extinct sea creatures, and depending on what source you refer to, they date from the lower Ordovician to Triassic ages (500 to 190 million years ago). As they died, their shells accumulated in great numbers on the sea floor where they were aligned by currents, buried by sediments, and transformed over the ages preserved in black limestone. Today, this prehistoric sea floor is ironically, found in the dramatic Atlas Mountain Range in southern Morocco at the northern fringe of the Sahara Desert.

The term 'straight' cephalopods is used in this case to describe fossil examples of straight ammonoids called Baculites, straight nautiloids called Orthoceras and Belemnites. Their bodies were predominantly elongate with conical shells. Some of these creatures evolved into semi-coiled forms eventually giving rise to coiled cephalopods like ammonites and nautili. Another branch of straight-shelled cephalopods continued to coexist with the coiled forms on into the Pennsylvanian Period. These straight forms were much less diverse and abundant than the coiled cephalopods, as a whole.

Straight cephalopods were among the most advanced invertebrates of their time having eyes, jaws, and a sophisticated nervous system. These creatures were predators that swam freely using a jet propulsion system by squirting water from their bodies. They had tentacles and ink sacs also much like the present-day squid.

Except for belemnites, cephalopods had external shells with hollow internal chambers separated by walls called septa. A tube called the siphuncle, connected the body with the chambers allowing the animal to fill them with water or air, changing its buoyancy in order to rise or drop in the ocean. Only the last and largest chamber was occupied by the living animal. Belemnites were different in that they had internal shells called 'guards' which were covered with the soft, muscular tissues of their bodies. These shells were also chambered but much less complex than the straight varieties of nautiloids and ammonoids.

Straight cephalopods probably lived for one to six years, with the majority living two to four years. They fed on plankton (tiny free-floating organisms), sea lilies, and smaller orthoceras. Although many fed off the ocean floor, others may have caught plankton while floating or swimming via jet propulsion, expelling water through a funnel-like opening to propel them in the opposite direction. Because straight cephalopods lived exclusively in marine environments, their presence also indicates the location of prehistoric seas.

Healing Stones
As a healing stone, fossils are believed to increase life span, reduce toxins, anxiety, stress, balance the emotions, and make one more confident. Containing supernatural and physical healing powers, they promote a sense of pride and successes in business, leading on to be open to change and new ideas. Healers use fossils to enhance telepathy and stimulate the mind. Traditionally, fossils have been used to aid in reducing tiredness, fatigues, digestive disorders, and rheumatism.
