On September 24th I attended the official re-opening and rededication of the park, which in the past year has undergone a transformation, including the movement of the specimens, the construction of a short walking trail, the building of concrete slabs on which to display the specimens, and the addition of signage ref.: Fantastic Fossils download online How could a creature be preserved/fossilized over and over again during the course of 300+ million years and then vanish for some 80 million years only to reappear, alive and well, in modern oceans? Well, there are several explanations commonly given to explain such a phenomenon. Perhaps one of the more popular explanations is that the modern coelacanth is not the same creature as those coelacanths found in the fossil record ref.: Prehistoric Worlds: An download pdf Prehistoric Worlds: An Interactive Book.

As the bone slowly decayed, water infused with minerals seeped into the bone and replaced the chemicals in the bone with rock-like minerals. The process of fossilization involves the dissolving and replacement of the original minerals in the object with other minerals (and or permineralization - the filling up of spaces in fossils with minerals, and /or recrystallization in which a mineral changes its form) , source: Find, Collect, Discover and Learn: Famous Dinosaur Archaeology Dig Sites - Children's Biological Science of Fossils Books It concerns injuries seen in the remains of the fossil individual known as Skhul 9, dated at 91 ka.
