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.
Titus Sextius Africanus Titus Sextius Africanus Titus Sextius Africanus was a Roman senator who was deterred by Agrippina the Younger from marrying Junia Silana. He served as a suffect consul in 59 AD. In 62 AD, he took the census in the provinces of Gaul, together with Quintus Volusius Saturninus and Marcus Trebellius Maximus. Saturninus and Africanus were rivals, and both hated Trebellius, who took advantage of their rivalry to get the better of them. His name occurs in a fragment of the Fratres Arvales. Titus Sextius Cornelius Africanus, who served as a consul with Trajan in 112 AD, was related to Africanus.
