In 1939, a semi-official emblem for the League of Nations emerged: two five-pointed stars within a blue pentagon. They symbolised the Earth's five continents and five races. A bow at the top displayed the English name (League of Nations), while another at the bottom showed the French (SociÃ©tÃ© des Nations).
Large Cretaceous Fossil Crocodile Tooth - Morocco. This is a large Cretaceous aged fossil crocodile tooth from the Kem Kem Beds of Morocco. Many dealers labeling similar teeth as coming from sarcosuchus (The Super Croc) to make them easier to sell. There were several crocodile species living alongside each other in the Kem Kem Basin.
Shark teeth are the most common type of fossil for a number of reasons. First, shark teeth, like most teeth, are made of dentin, a hard calcified tissue that does not easily decompose. Dentin is harder and denser than bone.he skin of a shark is made of tiny denticles, which are made of the same enamel that teeth have, meaning they too can fossilize. Some more primitive sharks have spines in their fins that will fossilize. Finally, shark feces, or coprolites, are sometimes found preserved.
