Oldest sea reptile from Age of Dinosaurs found on Arctic island

For nearly 190 years, scientists have searched for the origins of ancient sea-going reptiles from the Age of Dinosaurs. Now a team of Swedish and Norwegian paleontologists has discovered remains of the earliest known ichthyosaur("fish-lizard") ...

Melting

Melting, or fusion, is a physical process that results in the phase change of a substance from a solid to a liquid. The internal energy of a substance is increased, typically by the application of heat or pressure, resulting in a rise of its temperature to the melting point, at which the rigid ordering of molecular entities in the solid breaks down to a less-ordered state and the solid liquefies. An object that has melted completely is molten. Substances in the molten state generally have reduced viscosity with elevated temperature; an exception to this maxim is the element sulfur, whose viscosity increases with higher temperatures in its molten state.

Some organic compounds melt through mesophases, states of partial order between solid and liquid.
