Carcharodontosaurus Teeth Fossils

These teeth are from Carcharodontosaurus (pronounced /karkərədontəsarəs/) saharicus was a gigantic carnivorous dinosaur that lived around 98 to 93 million years ago, during the Cretaceous Period.  It was as long, or longer, than Tyrannosaurus Rex, growing to an estimated 36-44 feet and weighing up to 8 tons. The name Carcharodontosaurus means 'shark tooth lizard', after the shark genus Carcharodon. Carcharodontosaurus is often referred to as the "African T-rex."  It is similar to North America ’s T-Rex, but, a bit larger - See Chart.

Carcharodontosaurus had enormous jaws and long, serrated teeth up to eight inches long (three times the length of this specimen). Paleontologists once thought that Carcharodontosaurus had the longest skull of any of the theropod dinosaurs.  However, the premaxilla and quadrate bones were missing from the original African skull, which led to misinterpretation of its actual size by researchers. A more modest length of 1.6 meters (5.2 ft) has now been proposed for the skull.

Spinosaurus Teeth Fossils

These teeth are from Spinosaurus aegyptiaecus, an enormous sail-fin dinosaur from the Cretaceous Period (about 98 to 95 million years ago).  This is the dinosaur featured in the recent movie, Jurassic Park III.  Spinosaurus was about the size of T-Rex and every bit as fierce.  

Spinosaurus was a huge meat-eating dinosaur.  It was about 40-50 feet long (12-15 m) and weighed up to 8 tons; it is the largest known spinosaurid (a type of large, meat-eating dinosaur).  Spinosaurus is called "spiny lizard" because it had a series of large neural spines up to 6 feet (1.8 m) long coming out of its back vertebrae, probably forming a sail-like fin that may have helped in  thermoregulation, mating rituals and/or intraspecies rivalry.  Spinosaurus was bipedal (it walked on two legs).  It had a large head with sharp, straight, non-serrated teeth in powerful, crocodile-like jaws. Its arms were smaller than its legs but were larger than the arms of most other theropods.  It may have gone on all fours at times.

Spinosaurus was a carnivore, a meat eater with huge teeth and powerful jaws. It ate dinosaurs and large fish. The teeth were long and sharp but had little or no serrations. It was a large, fierce predator that could perhaps even kill large sauropods.

These teeth are found near Taquiz, Ksar-es-souk region of Morocco, North Africa.

Trilobites are the most diverse group of extinct animals preserved in the fossil record. Nine orders of trilobites are recognized, into which 15,000+ species are placed.  Trilobites appeared some 600 million years ago during the Cambrian period, long before the fish inhabited the seas and the Dinosaurs roamed the land.  They belonged the phylum Anthropodal (joint-footed), a phylum which to this day represents the most successful (78%) of all animal life forms, including crabs, centipedes, spiders, shrimps and insects.  The Trilobites, living in shallow seas, flourished as swimmers, crawlers and burrowers for some 350 million years.

Whatever their size, all trilobite fossils have a similar body plan, being made up of three main body parts: a cephalon (head), a segmented thorax, and a pygidium (tail piece) as shown at left. However, the name "trilobite," which means "three lobed," is not in reference to those three body parts mentioned above, but to the fact that all trilobites bear a long central, or axial lobe, flanked on each side by right and left pleural lobes.

Trilobites first capturing man's eye some 25,000 years ago in France where two specimens were found is association with a Cro-magnon settlement, at a site called "La Grotte du Trilobite", one was found with a hole drilled into it and worn as an adornment. Others have been found in the tombs of Egypt, Greece and Rome.  They were also sold on the street of 15th Century Europe and collected by Thomas Jefferson and Benjamin Franklin.

Ammonites, as they pertain specifically to the order Ammonitida, are an extinct group of marine animals belonging to the cephalopod subclass Ammonoidea. They are excellent index fossils, being found in sediments from 200 to 66 million year ago.  It is often possible to link the rock layer in which they are found to specific geological time periods.

The closest living relative of the Ammonitida, is not the modern Nautilus which they somewhat outwardly resemble, but rather the subclass Coleoidea (octopus, squid, and cuttlefish).

Their fossil shells usually take the form of planispirals, although there were some helically-spiraled and non-spiraled forms (known as "heteromorphs"). Their name came from their spiral shape as their fossilized shells somewhat resemble tightly-coiled rams' horns. Pliny the Elder (d. 79 A.D. near Pompeii) called fossils of these animals ammonis cornua ("horns of Ammon") because the Egyptian god Ammon (Amun) was typically depicted wearing ram's horns. Often the name of an ammonite genus ends in -ceras, which is Greek (κέρας) for "horn" (for instance, Pleuroceras).
