Vlei Rat
African vlei rats (''Otomys''), also known as groove-toothed rats, live in many areas of sub-Saharan Africa. Most species live in marshlands, grasslands, and similar habitats and feed on the vegetation of such areas, occasionally supplementing it with roots and seeds. The name "vlei" refers to the South African term for intermittent, seasonal, or perennial bodies of standing water. ''Otomys'' are compact rodents with a tendency to shorter faces and legs than other types of rats. The tails also are shorter than most Muridae, typically between one third and two thirds of the body length. The coat colour varies according to species,The Kingdon Pocket Guide to African Mammals, Jonathan Kingdon (2004) Russel Friedman Books but generally they have the brown-to-grey agouti coats typical of mice and other small wild rodents. Species living in warm or temperate regions tend to have unusually large ears for murids (e.g. ''Otomys irroratus''), whereas some of the alpine species, such as ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Thomas's Vlei Rat
Thomas's vlei rat (''Otomys thomasi'') is a species of rodent in the family Muridae. It is endemic to Kenya's high plateau mountains of the Rift Valley. Taxonomy Osgood (1910) initially described this species as ''Otomys thomasi''. In 2006, it would be included under ''Otomys orestes'' ( afroalpine vlei rat) by Carleton & Byrne. Taylor et al. (2011) reviewed the genus ''Otomys'' and moved ''Otomys thomasi'' back to species status. Conservation It is known from less than 10 locations in Kenya and isn't recorded in protected areas, hence the assessment of the species as " Vulnerable" by the IUCN The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources.
