There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangular upper, and non-functional. The type of tooth that a shark has depends on its diet and feeding habits. Sharks are a great model organism to study because they continually produce highly mineralized tissues. [2]
In this model, the great white shark is more closely related to the extinct broad-toothed mako (Isurus hastalis) than to megalodon, as evidenced by more similar dentition in those two sharks; megalodon teeth have much finer serrations than great white shark teeth. The great white shark is more closely related to the mako sharks (Isurus spp ...
A great white shark was captured near Kangaroo Island in Australia on 1 April 1987. This shark was estimated to be more than 6.9 m (23 ft) long by Peter Resiley, [67] [73] and has been designated as KANGA. [72] Another great white shark was caught in Malta by Alfredo Cutajar on 16 April 1987. This shark was also estimated to be around 7.13 m ...

A massive shark tooth scooped from the central Pacific Ocean floor is likely millions of years old, researchers said. The tooth was found a little more than 10,000 feet deep “on an unnamed ...
Shark teeth are strong and made of enamel. Many sharks have 3 rows of teeth. These teeth are embedded in the gums, not the jaw. [10] Sharks are born with teeth that are constantly being replaced. Teeth are replaced every two weeks, approximately. [10] The shape of the teeth determine the diet of the shark.
Like the extant great white shark, it is likely that males could have reached sexual maturity earlier than females. [12] [13] O. angustidens also had a faster growth rate than the extant great white shark, while O. auriculatus and the extant great white shark had a similar growth rate.
Its jaws were lined with sharp, recurved, serrated teeth that bear striking resemblances to those of the great white shark (genus Carcharodon), the inspiration for the name. Though giant, its cranium was made lighter by greatly expanded fossae and fenestra, but also making it more fragile than tyrannosaurids'.
