Copper is a chemical element with the symbol Cu (Latin: cuprum) and atomic number 29. It is a ductile metal, with very high thermal and electrical conductivity. Pure copper is rather soft and malleable, and a freshly exposed surface has a reddish-orange color. It is used as a thermal conductor, an electrical conductor, a building material, and a constituent of various metal alloys.
Plesippus is often considered an intermediary stage between Dinohippus and the present day genus, Equus. The famous fossils found near Hagerman, Idaho were originally thought to be a part of the genus Plesippus Hagerman Fossil Beds (in Idaho), a Pliocene site, dating about 3.5 Mya ago.
Scolecite is a tectosilicate mineral belonging to the zeolite group; it is a hydrated calcium silicate. Scolecite, like natrolite and mesolite, usually occurs as acicular (needle-like) and fibrous aggregations. It has nearly the same angles between the crystal faces as does natrolite, but natrolite is orthorhombic and scolecite is monoclinic.
