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.
Molarity (in units of mol/L, molar, or M) or molar concentration denotes the number of moles of a given substance per liter of solution. A capital letter M is used to abbreviate units of mol/L .
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.
