] Outside strict biological classification, the related term pachyderm is commonly used to describe elephants, rhinoceroses, hippopotamuses and tapirs. Cuvier himself defined Pachydermata as "animals with hoofs, non ruminants", whereas Storr had described it as "mammals with hoofs with more than two toes".
Rhinos and tapirs are more closely related to each other than to horses. The separation of horses from other perissodactyls took place according to molecular genetic analysis in the Paleocene some 56 million years ago, while the rhinos and tapirs split off in the lower-middle Eocene, about 47 million years ago.
Tapiroidea is a superfamily of perissodactyls which includes the modern tapirs and their extinct relatives. Taxonomically, they are placed in suborder Ceratomorpha along with the rhino superfamily, Rhinocerotoidea.The first members of Tapiroidea appeared during the Early Eocene, 55 million years ago, and were present in North America and Asia during the Eocene.
Brontotheriidae is a family of extinct mammals belonging to the order Perissodactyla, the order that includes horses, rhinoceroses, and tapirs.Superficially, they looked rather like rhinos with some developing bony nose horns, and were some of the earliest mammals to have evolved large body sizes of several tonnes.
A world first in rhinoceros reproductive health could save northern white rhinos from extinction, scientists said Wednesday. The team at the BioRescue project successfully impregnated a southern ...
Equidae (commonly known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, asses, and zebras, and many other species known only from fossils. The family evolved more than 50 million years ago, in the Eocene epoch, from a small, multi-toed ungulate into larger, single-toed animals.
The samples were collected from two rhinos that were less than 2 years old, two that were between 3 and 7 years old, two adult rhinos that had given birth at the zoo, and two that had been unable to.
The movie "Gladiator II" features scenes involving rhinos, baboons and sharks. A professor explains whether these animals were actually featured in the Roman Colosseum.
