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.
Adult beetles are fast runners and fliers. When they fly, they usually stay within three feet of the ground. Tiger beetles catch prey on the ground and in the air. Six-spotted Tiger Beetles eat small insects, spiders, and other arthropods. Favorite foods include other beetles, springtails, sawflies, caterpillars, flies, ants, and grasshoppers.
