Fossilized shark teeth guide. Any idea what kind of shark this one is from? Nice Post Alyson! Myrtle beach is one of our favorite family destination in South Carolina. We've been there a couple of times and we never get tired of going back! The beaches on the grand stand are marvelous and the shows on Medieval Times is entertaining. Hi Alyson! Your posts are really great to read, like listening to you talk, I guess? Love the honesty and so much to see and read, I started reading but will have to work my way through the whole blog bit by bit.
Nice to see some places we have been and many we haven't but are on the to go list. Like Australia, never been yet, so looking forward to see it.
Anyway, thanks for sharing! Who knew!? I sure didn't. I grew up going to Myrtle Beach every summer and never knew it was a great place for sharks teeth. All I ever found was jellyfish! Enjoy your time in my home state. That is an extremely well written article. Thank you for the post.
Do you have a place I can send a pic of a tooth I found they all look the same kinda? Maybe you could identify it for me? Is it rare to find them anymore along the shoreline or on the sand bars during low tides? Thanks for all the information! I am an avid collector! I just came back from gulf shores Alabama. I found 3 teeth. One is an obvious shark tooth. One looks like a prehistoric tooth or even maybe a claw. Where can I get these identified? How can I send you a picture. I showed them to the guy working on the beach, and he had no idea.
He wanted to know himself. Thanks so much! Send a pic to my email gypsyrosewraps gmail. Hey guys , I dove that area this weekend and found a nice tooth , My name is J Jose and looking for a boat ride. About inch two inches.

Cartilage does not mineralize to the extent that bone does, and as a result breaks down much quicker and easier than bony elements.
Teeth are the most common part of the shark that is fossilized, but it is not uncommon to also find individual vertebral centra in the same sediments.
In very rare instances when an individual is buried very quickly under the right circumstances, portions of the cartilage can be preserved. This is seen in environments that are low energy with high sedimentation rates. These specimens can preserve the neurocranium, teeth, and articulated vertebral centra. Why are fossil shark teeth different colors? 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. Different minerals turn different colors as they form and react with trace amounts of oxygen. For example, as iron oxidizes it begins to rust and typically turns a reddish brown. The same can happen to fossils. Where can you find fossil shark teeth?
In general, fossils are found in sedimentary rocks or unconsolidated sediments. These are rocks that formed through the compression of loose sediments, like sands, muds, silts, and clays over thousands or millions of years. In Florida, many of these sediments have not been around long enough to compress into rock yet, and are still unconsolidated.
Fossil shark teeth are found in sedimentary rocks that are specifically marine-derived, meaning that the sediments were originally laid down underwater in the ocean. This means that sediments originally deposited underwater 10, years ago, may be on dry land today. To find fossil shark teeth today, you must find exposed sediments or sedimentary rocks that are marine-derived.
In Florida, that is relatively easy because the state is surrounded by water and has been periodically submerged during high stands of the oceans in the past.
