Equus (genus) 54 million years ago (Mya). These animals had three toes on the hind feet and four on the front feet with small hooves in place of claws, but also had soft pads.<ref name="doi10.1126/science.1105458"></ref> Equids developed into larger, three-toed animals (e.g. "Mesohippus") during the Oligocene and Miocene. From there, the side toes became progressively smaller through the Pleistocene until the emergence of the single-toed "Equus". The genus "Equus", which includes all extant equines, is believed to have evolved from "Dinohippus", via the intermediate form "Plesippus". One of the oldest species is "Equus simplicidens", described as zebra-like with a donkey-like head shape.
Vauxhall Equus Vauxhall Equus The Vauxhall Equus was a two-door concept car first presented by Vauxhall in 1978. The name "Equus" is Latin for "Horse". It was the last concept car from Vauxhall until 2003. The Equus was based on a Panther Lima chassis, which itself was based on Vauxhall Magnum mechanicals. Panther built the prototype. The Equus was styled by a small team led by Wayne Cherry along with his chief designer John Taylor. Work started in October 1977 and the car was unveiled at the Birmingham NEC Motor Show in 1978. The design brief emphasized the use of Vauxhall parts
