The shark then throws its head back and forth, which allows a piece to be torn loose and swallowed whole. Since almost all sharks are carnivores, most of the teeth found are sharp, pointed, and triangular-shaped. Dense, flattened teeth are used for crushing; sharp, needle-like teeth for gripping; and the serrated triangular upper teeth do the cutting.
This makes for plenty to collect—from the shiny black fossilized teeth that date back millions of years to a glistening white tooth from the shark that swam by last week. Modern forms of sharks began to evolve during the Jurassic Period, the time of the giant dinosaurs.

Shark teeth cannot find collected for just any type of rock. Any fossils, including fossil shark teeth, are preserved in sedimentary rocks after falling from their mouth. The sediment prevents oxygen and bacteria for attacking and decaying the identification. Fossilized shark teeth find often be found for or near river dating banks, sand pits, and beaches.
Shark teeth fossils are in abundance at nearly every beach I have been to in Note: This is my largest Instructable to date and I have added many notes of the.
Megalodon , Carcharocles megalodon , member of an extinct species of megatooth shark Otodontidae that is considered to be the largest shark, as well as the largest fish , that ever lived. Fossils attributed to megalodon have been found dating from the early Miocene Epoch which began 23 million years ago to the end of the Pliocene Epoch about 2. Fossil remains of megalodon have been found in shallow tropical and temperate seas along the coastlines and continental shelf regions of all continents except Antarctica.
During the early and middle parts of the Miocene Epoch which lasted from 23 million to 5. Throughout the Miocene, megalodon distribution expanded from pockets located in the Caribbean and Mediterranean seas , in the Bay of Bengal , and along the coasts of California and southern Australia to encompass waters off the coasts of northern Europe, South America, southern Africa, New Zealand , and east Asia. Megalodon was the largest fish ever known, a designation based on discoveries of hundreds of fossil teeth and a handful of vertebrae.
Tooth-shape similarities between megalodon and modern great white sharks Carcharodon carcharias suggest that the two species may have been close relatives, and thus megalodon likely resembled that species in appearance—that is, as a bulky torpedo-shaped fish with a conical snout, large pectoral and dorsal fins, and a strong crescent-shaped tail. This data suggests that mature adult megalodons had a mean length of Some scientists, however, contend that the largest forms may have measured up to 25 metres 82 feet long.
Megalodon teeth are similar to those of modern white sharks in that they are triangular, serrated, and symmetrical. The largest extant megalodon tooth measures In addition, megalodon possessed a ferocious bite; its bite diameter was 3 metres about 9.

A rich engineering literature exists that is applicable to many aspects of vertebrate jaw mechanics and has been referred to in many studies in this sector. But mechanical engineering technology has provided few theoretical bases that are directly helpful in the study of predator teeth. Hence, analyses of puncturing and slicing functions of these teeth have lacked a firm physical technology as a background.
Predator teeth have evolved to pierce and cut animal tissues that are usually compliant in that they readily undergo relatively large deformations under applied stress before they actually yield.

You can find both fossils and newer teeth. Sharks are constantly losing teeth, and as they do so, a new one moves up to take its place. Sharks have 4 rows of teeth and loose hundreds of them daily. When the lost teeth sink to the bottom of the ocean and becomes buried in sediment, it begins to fossilize. The minerals in the sediment gradually replace the original tooth material. This process takes thousands of years to complete.
A general rule is that a fossil is over years old. Fossilized shark teeth are different colors, depending on the sediment in which they were buried. Most are black and dark grey, while some are brown or tan.
