   Some of the biggest shark teeth to be found are heavy and therefore do not easily get washed back into the ocean. However, to find these large fossilized teeth, you’ve got to look under the surface, or at least where sand is being moved, such as the edges of sand banks.

   Sep 04,  · The color of fossil shark teeth is a result of the minerals that are present in the surrounding sediments. Teeth fossilize through a process called permineralization. As water seeps through sediments over the teeth, it transports the minerals that are found in the sediment. These minerals fill in pore spaces in the tooth causing them to fossilize.

   Shark species including bull sharks and blue sharks have needle-like teeth. These teeth are often used to feed on fish or other small sharks and are very effective for grasping slippery meals. Sharks with needle-like teeth will also feed on prey such as stingrays, squid, flounder, and even other sharks such as smaller hammerheads.

   Nov 18,  · Shark teeth that are found in areas that contain iron oxide, such as parts of New Jersey, tend to have an orange or red coloring. Shark teeth found in areas that contain a lot of phosphate, such as Venice Beach, Florida, tend to be black, as phosphate is a dense, black mineral%().

   Jun 24,  · Know what shark’s teeth look like. Shark teeth vary among the different species, but they tend to be the shape of a triangle and are commonly ⅛ to ¾ inches long. Some teeth are larger, especially the teeth found in deeper waters. Shark teeth are also almost always black, so look for both white and black shapes.

   Oct 23,  · Although shark teeth can be found all along the shores of Jacksonville, there are a few places where the searching is better than others. Mickler’s Beach in Ponte Vedra is known for having great shark teeth hunting, but really any beach with patches of shell debris are good for searching.. Go at the Right Time to Hunt for Shark Teeth.

   Shark teeth are relics of shark evolution and biology. Shark skeletons are composed entirely of cartilage. Often the only parts of the shark to survive as are teeth. Fossil shark teeth have been dated back hundreds of millions of years. The most ancient types of sharks date back to million years ago, and they are mostly known from their fossilized teeth. The earliest known fossil shark.
