From an extremely rare locale, we offer this set of 5 Bull Shark, Carcharhinus sp. fossils found in the Sahara Desert in Niger. All were found together and likely from the same shark. The fossils come from the Middle to Late Eocene Period which is an additional rarity. This is a VERY HIGHLY RECOMMENDED collection for advanced shark fossil collectors. There are 4 teeth and a single vertebra. This is only one of two sets that were collected and all we have to offer is this set and the other being simultaneously listed. We don't know of any other source on the public market that is offering shark fossils from Niger and of this period and genus.
The Bull Shark is recognized by a combination of characters including a stout body, short blunt snout, triangular serrated teeth in the upper jaw and no fin markings as an adult. This species has a second dorsal fin about one third the height of the first, a small eye, and no skin ridge between the two dorsal fins. It is gray to light brown above and pale below, sometimes with a pale stripe on the flank. Similar to the Sandbar Shark but has a shorter, wider snout. The large first dorsal fin starts above the middle of the pectoral fin, whereas in the Sandbar it starts above the front portion of the pectoral. Female bull sharks are usually larger than the males and can grow up to 11 feet.
The Bull Shark is considered to be the most dangerous shark in the world, even surpassing the Great White Shark. It has broad, serrated triangular upper teeth and very powerful jaws. It has a broad diet and will eat almost anything. Studies believe it lives for about 14 years and prefers to breed in the mouth of rivers.
