Michigan's Fossil Whales The discovery of fossil whale bones in Michigan has been a source of some embarrassment for the conventional geologic story of the history of the Great Lakes region, and the notion that the area has remained above sea level for 290 million years since the end of the Pennsylvanian period, as whale fossils are obviously evidence that the land was submerged beneath … Can you keep a protected species part found on the beach?

Most of the whales in the North Pacific Ocean have black pectoral flippers, though there ar對e some whales which have white flippers. You may not collect parts from a carcass or parts with soft tissues attached. These flippers can grow to lengths of about 15 feet, which is abo\൵t 1/3 of the whale’s total length. Killer whale teeth are smaller. Large toothed whales like the Sperm whale were prime victims of the Megalodon shark. In most cases, when bones are found in groups, they are often accompanied by Megalodon teeth indicating they were an important food source for the massive Megalodon shark. Also known as baleen, whalebone is not a bone at all, but the keratinous material found around the upper jaws of baleen whales, used to filter plankton and krill. I currently get about 750 emails a year and try to reply to every one. The rest of the tooth is covered by cementum. One surprise, though, was the volume of bone belonging to fin whale species in the assemblage.
