Fossils
Fossils are present in high numbers and often show excellent quality of preservation. The most conspicuous fossils are the skeletons and bones of whales and sea cows, and over several hundred fossils of these have been documented. The fossils of whales vary from single bones to entire skeletons, and a number of partial skeletons are currently on display in the public part of the park. The two common whales are the large Basilosaurus, and the smaller (3 to 5 metre) Dorudon. At least two other species are known from rarer remains. The whales possess small hind limbs, that are not seen in modern whales, and a powerful skull with teeth similar to those of carnivorous land mammals. Other mammals are represented by the skeletons of three species of sirenia or sea cows. These were fully marine like the whales, and likewise show primitive features not seen in modern species and possess teeth that suggest that they grazed on seagrasses and other marine plants. Bones of the primitive elephant Moeritherium have also been recorded. Fossil reptiles are represented by fossils of crocodiles and sea turtles, and bones of sea snakes have also been recorded. There are many species of bony fish, sharks and rays represented, but most of the fossils are isolated small teeth and these are not often conspicuous. Larger fish fossils include the rostra and pegs of sawfish; a sawfish rostrum of 1.8 metres long is laid out in the park. Fossil shells are not common in the main whale-bearing rocks, but are very common in other rocks; many fallen rocks can be seen to be full of a wide variety of fossil shells. Disc-shaped nummulite fossils are common in places, and often coat the desert floor. A large log is present in the park, and this is full of tubular shipworm fossils. Some fossil seagrasses are also known.

Famous quotes containing the word fossils:
“You can hardly convince a man of an error in a life-time, but must content yourself with the reflection that the progress of science is slow. If he is not convinced, his grandchildren may be. The geologists tell us that it took one hundred years to prove that fossils are organic, and one hundred and fifty more to prove that they are not to be referred to the Noachian deluge.”
—Henry David Thoreau (1817–1862)
“In early times, before the floods swept across the world, there was life, albeit odd, as one can see from the fossils of mammoth bones, and there was the regime of Prince Metternich.”
—Franz Grillparzer (1791–1872)
