Ammonites are extinct members of the cephalopod group of mollusks. Only a limited number of species have survived to the present day which includes the squid and the chambered nautilus. Ammonites had a multi-chambered shell, and added more chambers as it grew, always living in the outer chamber.  They lived in the Cretaceous period some 63 to 130 million years ago.

These Moroccan fossils are among the oldest cephalopods.  They were abundant during the Paleozoic era some 350 MM years ago and now make up the Atlas Mountain range of central Morocco. There were two Nautiloid forms present in the Moroccan Devonian sea.  The Goniatites is an extinct relative of the Ammonites,  it possessed an external shell, which is has a spiral form with internal chambers. The Orthoceras was straight shelled cephalopod with the internal chambers. They were related to the modern day chambered nautilus and the squid.

Trilobites are hard-shelled, segmented members of Arthropoda and the class Trilobita that existed throughout almost all of the Paleozoic era, flourishing in the earlier part of it and slowly declining in the later part. The most common trilobites were about 2-7 cm (1-3.5 in) in length, but over their long history they ranged in size from 1 mm-72 cm (.04 in-28 in) and exhibited so much variation that they are classified into nine (or possibly ten) orders with more than 15,000 species. The smallest species are presumed to have been part of the free floating plankton, while the more common, mid-sized species probably walked along the sea floor filtering mud to obtain food, and the larger varieties may have been swimming predators.

$40.00 FO511c    Here is a very nice specimen of South Dakota Baculite.  The Baculite fossil measures approximately 7" x 2" x 1 3/4"  in a matrix that measures 6 1/4" x 4" x 2"and has not been polished.  This fossil has a nice "fish scale like" color with good detail and gorgeous "rainbow" iridescent colors (which was difficult to capture in the photos, the colors are so much more brilliant than shown). There are a few fractures but this is common and does not affect the stability of this terrific fossil. A great way to begin your fossil collection.

Sand Shark or Otodus obliquus – (the Great Grandfather of the Megalodon) is one of the earliest mackerel sharks. These teeth are noted for their wide triangular crown and large side cusps (occasionally multiple side cusps). The Otodus obliquus was the king of the early Eocene, approximately 50-55 million years ago. These large teeth are very showy, making them a must have for every fossil shark teeth collection. Large Otodus obliquus teeth are not easily located in the phosphate pits in Atlas Mountains of Morocco, but can still be affordable.

This tooth is from the largest shark ever known to live.  The Carcharocles Megalodon sometimes ranged in size up to 60' in length and weighed over 52 tons.  This huge monster is the largest predatory fish that ever lived, second only in size to the sperm whale.  Fossil teeth have been found that exceed 7 inches in length.  These sharks lived in the Miocene period some 23 million years ago to the Mid Pliocene times, 3.6 million years ago.  This specimen is from South Carolina.
