What are they?
Dinosaur bones are the fossilised remains of ancient reptiles that roamed the Earth during the Mesozoic Era, a time span that lasted from approximately 245 to 66 million years ago. These bones, which were once part of living creatures, have undergone a fascinating transformation into rock over millions of years. This process, known as permineralisation, occurs when minerals carried by groundwater seep into the porous bone structure, gradually replacing the original biological material with solid mineral deposits. As a result, what we see today in museums and research sites are enduring remains of a world long gone, offering us invaluable insights into the lives of these prehistoric giants.
