In the 1940s, American paleontologist George Gaylord Simpson coined the term sweepstakes hypothesis for such random events.

Road works excavations

And there'd also be an extinction event like fossils would suddenly disappear.

Many other fossils are also known.

A zone includes strata characterised by the overlapping range of fossils.

From 1877 to 1892, both paleontologists used their wealth and influence to finance their own expeditions and to procure services and dinosaur bones from fossil hunters.

There have been many other notable fossil findings in the country.

Featherstonhaugh liked climbing cliffs, collecting fossils, and gathering wild bird eggs to sell.

Index fossils are one of the species from the assemblage of species that characterise the zone.

Excavations in its lower layers produced a series of radiocarbon dates as of 6000 BC.

Often a fossil would be found by a quarryman, construction worker, or road worker who would sell it to a wealthy collector, and it was the latter who was credited if the find was of scientific interest.

Fossils from there contain DNA related to, but distinct from, that of the Neanderthals.

Also common in the upper parts of the member are thin interbeds of carbonate rock with some fossils.

The regular order of occurrence of fossils in rock layers was discovered around 1800 by William Smith.

Archaeological excavations show that, at the lowest level, the Roman engineers had placed a loose layer of stones.

So there were Well, you know, the the fossil record is truly amazing because it really forces you to look at living animals in a new way.

Rare earth elements change through time in small quantities (ppm, parts per million), so their proportion can be used for geochronology and dating fossils.

While digging the Somerset Coal Canal in southwest England, he found that fossils were always in the same order in the rock layers.

And many, many hundreds of skulls like this have been found in archaeological sites all over the world, dating back five to 10 thousand years.

During the middle of the 20th century, anthropologists discovered many fossils and evidence of human occupation perhaps as early as 7 million years ago.

The order has 33 extant families, 413 genera, and over 13000 described species, along with five extinct genera known only from the fossil record.

The walls of the causeway were covered with painted reliefs throughout, some of which were discovered during the excavations started in the mid 1990s of the upper part of the causeway.

And the worlds of royalty and popular fame often overlap.

Young people represent not only the world of tomorrow, but also that of today.

A World of Vulnerability

Petroleum and other fossil fuels (coal and natural gas) are causing long term changes in the global climate, but few people appreciate the risks.

Their historical importance is, however, mostly due to their legacy of carved rocks, c. 300,000 in number, which date from the Palaeolithic to the Middle Ages.

Marcus Ward Lyon, Jr. (February 5, 1875 May 19, 1942) was an American mammalogist, bacteriologist, and pathologist.

A shaman organizes this important journey, where the elephant leaves the forest world for the human world.

Carbon Capture and Sequestration that's what CCS stands for is likely to become the killer app that will enable us to continue to use fossil fuels in a way that is safe.

So this whole world, the nano world, this area in here is called the nano world, and the nano world, the whole micro world that we see, there's a nano world that is wrapped up within that, and the whole and that is the world of molecules and atoms.
