Fossil age dating
When miners were sinking a ventilation shaft for the new Crinum Coal Mine in Central Queensland in 1993 (see map below) they unearthed a rare find.After digging through the thin surface sands and clays, followed by basalt, 21 metres (almost 69 feet) down they found pieces of wood entombed in the bottom basalt flow.
PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.Both the botanical and animal inclusions not only add beauty, but also are of potential scientific value in the study of taxonomy and evolution.Animal inclusions are usually invertebrates, specifically arthropods, and only extremely rarely a vertebrate such as a tiny lizard.For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.
By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.
A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.
However, by itself a fossil has little meaning unless it is placed within some context.
Amber is also valued for its botanical and animal inclusions that are trapped by the sticky resin as it flows as sap, which is also organic.
Of course, other life is captured including microscopic bacteria that often produce gas bubbles, and various fungi.
