The bone in these fake jaws are typically crudely constructed out of plaster, animal bone, fossil fragments or a combination of the three and mounted in fake matrix. In the matrix calcium is in the form of hydroxyapatite crystals [Ca 10 (PO 4) 6 (OH) 2] which are deposited between the fibrous elements. With direct evidence, ancient organisms are preserved without any alteration. Either conditions were not right for fossilization or not enough time has passed for it to be fossilized (ie, replaced by minerals or by some other means turne A fossil forms when a skeleton is preserved in rock over millions of years. The fossil may have lost water, or color, or the proteins of the soft tissue may have degraded.

Dire wolf remains have been radiocarbon dated to 8,200 YBP from Whitewater Draw in Arizona, However, one author has stated that radiocarbon dating of bone carbonate is known to be unreliable, and that while many dire wolf remains are found in fossil assemblages dated to the terminal Pleistocene, there are no confirmed Holocene finds. As an example of modern, recent bone, the Indian elephant (Elephas indicus) was used. But a buried bone isn't the same thing as a fossil -- to become a fossil, the bone has to become rock. From there you will be sent to the Glittering Cave to find the research assistant and he will give you the option between two fossils.
