There are lots of types of rock and each type has different properties and uses. For example, some are strong and hard but others are soft and sandy. Some rocks are harder than others. For example ...

Numerical ages estimate the date of a geological event and can sometimes reveal quite precisely when a fossil species existed in time. Third, magnetism in rocks can be used to estimate the age of ...

There are over 5,000 known types of minerals. Just a few minerals make up most of the rocks we see, though: feldspars, amphiboles, quartz, olivine, garnet, micas, calcite, and pyroxenes.

The characteristics of the rocks that hold fossils can be as informative as the fossils themselves. There are three main types of rock: igneous rock, metamorphic rock, and sedimentary rock. Almost all ...

Researchers could identify it contained two distinct cell types thanks to the ... taken from the Torridon area's ancient rocks and find more fossils that could provide further insights into ...

The music-related monikers were originally pet names, says Sutton, because the spike-laden fossils were reminiscent of hairstyles from the punk rock movement, but the names stuck, leading to the ...
