Fossils of organisms' bodies are usually the most informative type of evidence. The most common types are wood, bones, and shells. [57] Fossilisation is a rare event, and most fossils are destroyed by erosion or metamorphism before they can be observed. Hence the fossil record is very incomplete, increasingly so further back in time.
The new fossil was 10% larger than other specimens and estimated to weigh 10–13 tons in life. [3] The Museum of the Rockies, as the result of continuing fieldwork, now exhibits the largest Tyrannosaurus rex collection in the world. Currently, Horner is working on the developmental biology of dinosaurs. [16]
The history of paleontology traces the history of the effort to understand the history of life on Earth by studying the fossil record left behind by living organisms. Since it is concerned with understanding living organisms of the past, paleontology can be considered to be a field of biology, but its historical development has been closely tied to geology and the effort to understand the ...
Fossil collecting (sometimes, in a non-scientific sense, fossil hunting) is the collection of fossils for scientific study, hobby, or profit. Fossil collecting, as practiced by amateurs, is the predecessor of modern paleontology and many still collect fossils and study fossils as amateurs.
The fossil filled a 70-million-year gap in the understanding of how the brains of birds evolved: between the 150-million-year-old Archaeopteryx, the earliest known bird-like dinosaur, and birds ...
This is a list of archaeologists – people who study or practise archaeology, the study of the human past through material remains. This is a dynamic list and may never be able to satisfy particular standards for completeness.
A rare fossil of an adolescent Tyrannosaurus rex has been excavated in North Dakota's badlands - a find noteworthy for the scientific insight it may offer into the life history of this famous ...
A new analysis of fossil faeces has revealed what the environmental conditions were like at the time dinosaurs started to take over the Earth.. Researchers found undigested remains of food, plants ...
