Fossils for kids

Now: Whale Tooth
Then: Prehistoric Sperm Whale
Whales have changed little over the past 20,000,000 years.  They have increased in size but their
eating habits and social activity has basically remained the same all this time.  Sperm whales were
an important part of the giant shark, Megalodon's, diet.  Teeth, vertebrae, and rib bones are
common fossils found in Miocene marine fauna.
