- Lot Description
Ancient Seas, Morocco, Tindouf Basin, Devonian Period, ca. 419.2 to 358.9 million years ago. A stone matrix filled with wonderful Orthoceras fossils of the Geisenoceras genus that were once part of the prehistoric ocean floor over 400 million years ago! As these forms of prehistoric squid were covered in ocean sediments prior to fossilization, most of these creatures faced the same relative position, having been lined up by currents on the sea floor prior to being buried. The Orthoceras bodies were elongated with conical shells that protected their soft tentacles and a beak; their fleshy bodies decayed long before the fossilization process could occur. These fossilized shells are exposed and prepared with their pointed forms rising from the matrix and given a high polish to better view the creatures and give contrast against the rest of the stone. Each polished spire contains at least one full shell, and some have partial pieces as well. The high relief as well as dramatic texture and details make this almost an abstract modernist sculpture! The bottom has been cut to form a flat, stable base and these fossils could make an interesting centerpiece on a table or mantle. Size: 10.5" L x 5" W x 11.125" H (26.7 cm x 12.7 cm x 28.3 cm)
Prehistoric 'straight' cephalopods include straight ammonoids called orthoceras. Cephalopod evolution began during the Late Cambrian Period. Some of these creatures evolved into semi-coiled forms, eventually giving rise to coiled cephalopods like ammonites and nautili. Straight cephalopods were among the most advanced invertebrates of their time, with 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, much like 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.
