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.
Selenogyrus africanus Andrew Smith claimed that "Selenogyrus africanus" "is in urgent need of redescription". Selenogyrus africanus Selenogyrus africanus is a species of tarantula, which is native to the Ivory Coast and is a member of the Selenogyrinae subfamily. Female "Selenogyrus africanus" have procurved foveae, and many spines on the labium. The cephalothorax is 12mm long and 9.4mm wide. It has some long, thick greyish-yellow hairs. The abdomen is 15mm long and 10mm wide. It is black, with long grey hairs. "Selenogyrus africanus" was originally described as "Hapalopus africanus" by Eugène Simon in 1889, but Reginald Innes Pocock, in 1897, recognized that it
