After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
The fossil provides a rare glimpse into a time of global environmental changes and faunal turnover, when some species go extinct while new ones are introduced due to varying changes in the habitat ...
Unlike body fossils, which can be transported far away from where an individual organism lived, trace fossils record the type of environment an animal actually inhabited and thus can provide a more accurate palaeoecological sample than body fossils.
There have been some discoveries of unusually well-preserved fossil dinosaur specimens which bear remnants of tissues and bodily structures.Organic tissue was previously thought to decay too quickly to enter the fossil record, unlike more mineralised bones and teeth, however, research now suggests the potential for the long-term preservation of original soft tissues over geological time, [1 ...
For example, typical dinosaur fossils are bones turned to stone and preserved from the passage of time located, if we’re particularly lucky, in large collections that can be reassembled to ...
The fossils were unearthe. About 280 million years ago, a large creature built somewhat like a salamander but with frightful fangs prowled the swamps and lakes of what is now Namibia, ambushing ...
Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the fossil record. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good ...
These three-dimensional fossils create permanent molds of internal structures. The mineralization process helps prevent tissue compaction, distorting organs' actual size. A permineralized fossil will also reveal much about an organism's environment and the substances found in it since it preserves soft body parts.
