I've included three links, as I found your question very interesting. To be a fossil or ancient remnant, it helps to be in abundance. Sharks lose their teeth and grow new ones. It is important that the remains are not subject to decomposition. The sharks teeth are very hard and covered with enamel. The shark's body is made of cartilage and easily decomposes, so in time all that remains is his scales and teeth. Being buried in sediments or underwater, can protect the teeth from air and bacteria that can cause decomposition. Please see links for more information, including the awesome Stechacanthus shark. Also, one link states that shark's teeth come mostly from the Miocene period. It is probably true that most of the teeth found come from this period. However, sharks were around during the Paleozoic era, Devonian period, and survived the Permian-Triassic time period of massive extinctions. Really quite fascinating
